"Clothing tags, travel cards, hotel room key cards, parcel labels … a whole host of components in supply chains of everything from cars to clothes. What do they have in common? RFID tags.  

Every RFID (Radio Frequency Identification) tag contains a microchip and a tiny metal strip of an antenna. A cool 18bn of these are made – and disposed of – each year. And with demands for product traceability increasing, ironically in part because of concerns for the social and environmental health of the supply chain, that’s set to soar. 

And guess where most of these tags end up? Yup, landfill – adding to the burgeoning volumes of e-waste polluting our soils, rivers and skies. It’s a sorry tale, but it’s one in which two young graduates of Imperial College London and Royal College of Art are putting a great big green twist. Under the name of PulpaTronics, Chloe So and Barna Soma Biro reckon they’ve hit on a beguilingly simple sounding solution: make the tags out of paper. No plastic, no chips, no metal strips. Just paper, pure and … simple … ? Well, not quite, as we shall see. 

The apparent simplicity is achieved by some pretty cutting-edge technical innovation, aimed at stripping away both the metal antennae and the chips. If you can get rid of those, as Biro explains, you solve the e-waste problem at a stroke. But getting rid of things isn’t the typical approach to technical solutions, he adds. “I read a paper in Nature that set out how humans have a bias for solving problems through addition – by adding something new, rather than removing complexity, even if that’s the best approach.”   

And adding stuff to a world already stuffed, as it were, can create more problems than it solves. “So that became one of the guiding principles of PulpaTronics”, he says: stripping things down “to the bare minimum, where they are still functional, but have as low an environmental impact as possible”.  

...how did they achieve this magical simplification? The answer lies in lasers: these turn the paper into a conductive material, Biro explains, printing a pattern on the surface that can be ‘read’ by a scanner, rather like a QR code. It sounds like frontier technology, but it works, and PulpaTronics have patents pending to protect it. 

The resulting tag comes in two forms: in one, there is still a microchip, so that it can be read by existing scanners of the sort common within retailers, for example. The more advanced version does away with the chip altogether. This will need a different kind of scanner, currently in development, which PulpaTronics envisages issuing licences for others to manufacture. 

Crucially, the cost of both versions is significantly cheaper than existing RFID kit – making this a highly viable proposition. Then there are the carbon savings: up to 70% for the chipless version – so a no-brainer from a sustainability viewpoint too. All the same, industry interest was slow to start with but when PulpaTronics won a coveted Dezeen magazine award in late 2023, it snowballed, says So. Big brands such as UPS, DHL, Marks & Spencer and Decathlon came calling. “We were just bombarded.” Brands were fascinated by the innovation, she says, but even more by the price point, “because, like any business, they knew that green products can’t come with a premium”."

Note: I know it's still in the very early stages, but this is such a relief to see in the context of the environmental and human rights catastrophes associated with lithium mining and mining for rare earth metals, and the way that EVs and other green infrastructure are massively increasing the demand for those materials.

I'll take a future with paper-based, more humane alternatives for sure! Fingers crossed this keeps developing and develops well (and quickly).

Radio Frequency Identification (RFID) technology has emerged as a game-changer in industries where tracking, identification, and real-time data play pivotal roles. RFID tags have simplified and optimized processes from retail stores to hospitals by enhancing accuracy and efficiency. Today, we will discuss the world of RFID tags, their functioning, various types, and how industries across sectors leverage this technology to streamline operations.

What is RFID Technology?

RFID is Radio Frequency Identification, a wireless system for identifying and tracking objects. It works through electromagnetic fields to automatically identify and capture data from RFID tags attached to objects. These tags communicate with an RFID reader, which converts the data into usable information.

RFID technology eliminates the need for direct contact or line-of-sight scanning, which is vastly superior to traditional tracking methods like barcodes. RFID technology is most commonly used in supply chain management, inventory tracking, and identification. Whether for retail, asset management, or campus security, RFID technology is indispensable in modern business processes.

What are RFID Tags

RFID tags are small devices that contain a microchip and antenna, allowing them to communicate with an RFID reader via radio waves. The RFID reader sends out electromagnetic signals that activate the tag. Once activated, the tag transmits the stored data, which the reader captures and processes. Depending on the application, this data can include product information, location, or even security details.

How Do They Work?

There exist two primary categories of RFID tags: passive and active. Passive RFID tags do not have an internal power source and depend on the reader's electromagnetic energy to power them. They are often used for low-cost, high-volume applications like retail inventory management. Active RFID tags, on the other hand, are powered by an internal battery, allowing them to transmit data over longer distances and store more information. These are commonly used in logistics and industrial settings where higher data capacities and longer ranges are essential.

Asset Management with UHF RFID Technology

UHF RFID technology offers effective passive tracking of assets, items, and personnel by establishing detection zones through networked antennas. These antennas transmit radio waves beyond 50 feet, enabling real-time movement and location tracking.

Scan the online brochures of companies who sell workplace monitoring tech and you’d think the average American worker was a renegade poised to take their employer down at the next opportunity. “Nearly half of US employees admit to time theft!” “Biometric readers for enhanced accuracy!” “Offer staff benefits in a controlled way with Vending Machine Access!”

A new wave of return-to-office mandates has arrived since the New Year, including at JP Morgan Chase, leading advertising agency WPP, and Amazon—not to mention President Trump’s late January directive to the heads of federal agencies to “terminate remote work arrangements and require employees to return to work in-person … on a full-time basis.” Five years on from the pandemic, when the world showed how effectively many roles could be performed remotely or flexibly, what’s caused the sudden change of heart?

“There’s two things happening,” says global industry analyst Josh Bersin, who is based in California. “The economy is actually slowing down, so companies are hiring less. So there is a trend toward productivity in general, and then AI has forced virtually every company to reallocate resources toward AI projects.

“The expectation amongst CEOs is that’s going to eliminate a lot of jobs. A lot of these back-to-work mandates are due to frustration that both of those initiatives are hard to measure or hard to do when we don’t know what people are doing at home.”

The question is, what exactly are we returning to?

Take any consumer tech buzzword of the 21st century and chances are it’s already being widely used across the US to monitor time, attendance and, in some cases, the productivity of workers, in sectors such as manufacturing, retail, and fast food chains: RFID badges, GPS time clock apps, NFC apps, QR code clocking-in, Apple Watch badges, and palm, face, eye, voice, and finger scanners. Biometric scanners have long been sold to companies as a way to avoid hourly workers “buddy punching” for each other at the start and end of shifts—so-called “time theft.” A return-to-office mandate and its enforcement opens the door for similar scenarios for salaried staff.

Track and Trace

The latest, deluxe end point of these time and attendance tchotchkes and apps is something like Austin-headquartered HID’s OmniKey platform. Designed for factories, hospitals, universities and offices, this is essentially an all-encompassing RFID log-in and security system for employees, via smart cards, smartphone wallets, and wearables. These will not only monitor turnstile entrances, exits, and floor access by way of elevators but also parking, the use of meeting rooms, the cafeteria, printers, lockers, and yes, vending machine access.

These technologies, and more sophisticated worker location- and behavior-tracking systems, are expanding from blue-collar jobs to pink-collar industries and even white-collar office settings. Depending on the survey, approximately 70 to 80 percent of large US employers now use some form of employee monitoring, and the likes of PwC have explicitly told workers that managers will be tracking their location to enforce a three-day office week policy.

“Several of these earlier technologies, like RFID sensors and low-tech barcode scanners, have been used in manufacturing, in warehouses, or in other settings for some time,” says Wolfie Christl, a researcher of workplace surveillance for Cracked Labs, a nonprofit based in Vienna, Austria. “We’re moving toward the use of all kinds of sensor data, and this kind of technology is certainly now moving into the offices. However, I think for many of these, it’s questionable whether they really make sense there.”

What’s new, at least to the recent pandemic age of hybrid working, is the extent to which workers can now be tracked inside office buildings. Cracked Labs published a frankly terrifying 25-page case study report in November 2024 showing how systems of wireless networking, motion sensors, and Bluetooth beacons, whether intentionally or as a byproduct of their capabilities, can provide “behavioral monitoring and profiling” in office settings.

The project breaks the tech down into two categories: The first is technology that tracks desk presence and room occupancy, and the second monitors the indoor location, movement, and behavior of the people working inside the building.

To start with desk and room occupancy, Spacewell offers a mix of motion sensors installed under desks, in ceilings, and at doorways in “office spaces” and heat sensors and low-resolution visual sensors to show which desks and rooms are being used. Both real-time and trend data are available to managers via its “live data floorplan,” and the sensors also capture temperature, environmental, light intensity, and humidity data.

The Swiss-headquartered Locatee, meanwhile, uses existing badge and device data via Wi-Fi and LAN to continuously monitor clocking in and clocking out, time spent by workers at desks and on specific floors, and the number of hours and days spent by employees at the office per week. While the software displays aggregate rather than individual personal employee data to company executives, the Cracked Labs report points out that Locatee offers a segmented team analytics report which “reveals data on small groups.”

As more companies return to the office, the interest in this idea of “optimized” working spaces is growing fast. According to S&S Insider’s early 2025 analysis, the connected office was worth $43 billion in 2023 and will grow to $122.5 billion by 2032. Alongside this, IndustryARC predicts there will be a $4.5 billion employee-monitoring-technology market, mostly in North America, by 2026—the only issue being that the crossover between the two is blurry at best.

At the end of January, Logitech showed off its millimeter-wave radar Spot sensors, which are designed to allow employers to monitor whether rooms are being used and which rooms in the building are used the most. A Logitech rep told The Verge that the peel-and-stick devices, which also monitor VOCs, temperature, and humidity, could theoretically estimate the general placement of people in a meeting room.

As Christl explains, because of the functionality that these types of sensor-based systems offer, there is the very real possibility of a creep from legitimate applications, such as managing energy use, worker health and safety, and ensuring sufficient office resources into more intrusive purposes.

“For me, the main issue is that if companies use highly sensitive data like tracking the location of employees’ devices and smartphones indoors or even use motion detectors indoors,” he says, “then there must be totally reliable safeguards that this data is not being used for any other purposes.”

Big Brother Is Watching

This warning becomes even more pressing where workers’ indoor location, movement, and behavior are concerned. Cisco’s Spaces cloud platform has digitized 11 billion square feet of enterprise locations, producing 24.7 trillion location data points. The Spaces system is used by more than 8,800 businesses worldwide and is deployed by the likes of InterContinental Hotels Group, WeWork, the NHS Foundation, and San Jose State University, according to Cisco’s website.

While it has applications for retailers, restaurants, hotels, and event venues, many of its features are designed to function in office environments, including meeting room management and occupancy monitoring. Spaces is designed as a comprehensive, all-seeing eye into how employees (and customers and visitors, depending on the setting) and their connected devices, equipment, or “assets” move through physical spaces.

Cisco has achieved this by using its existing wireless infrastructure and combining data from Wi-Fi access points with Bluetooth tracking. Spaces offers employers both real-time views and historical data dashboards. The use cases? Everything from meeting-room scheduling and optimizing cleaning schedules to more invasive dashboards on employees’ entry and exit times, the duration of staff workdays, visit durations by floor, and other “behavior metrics.” This includes those related to performance, a feature pitched at manufacturing sites.

Some of these analytics use aggregate data, but Cracked Labs details how Spaces goes beyond this into personal data, with device usernames and identifiers that make it possible to single out individuals. While the ability to protect privacy by using MAC randomization is there, Cisco emphasizes that this makes indoor movement analytics “unreliable” and other applications impossible—leaving companies to make that decision themselves.

Management even has the ability to send employees nudge-style alerts based on their location in the building. An IBM application, based on Cisco’s underlying technology, offers to spot anomalies in occupancy patterns and send notifications to workers or their managers based on what it finds. Cisco’s Spaces can also incorporate video footage from Cisco security cameras and WebEx video conferencing hardware into the overall system of indoor movement monitoring; another example of function creep from security to employee tracking in the workplace.

“Cisco is simply everywhere. As soon as employers start to repurpose data that is being collected from networking or IT infrastructure, this quickly becomes very dangerous, from my perspective.” says Christl. “With this kind of indoor location tracking technology based on its Wi-Fi networks, I think that a vendor as major as Cisco has a responsibility to ensure it doesn’t suggest or market solutions that are really irresponsible to employers.

“I would consider any productivity and performance tracking very problematic when based on this kind of intrusive behavioral data.” WIRED approached Cisco for comment but didn’t receive a response before publication.

Cisco isn't alone in this, though. Similar to Spaces, Juniper’s Mist offers an indoor tracking system that uses both Wi-Fi networks and Bluetooth beacons to locate people, connected devices, and Bluetooth tagged badges on a real-time map, with the option of up to 13 months of historical data on worker behavior.

Juniper’s offering, for workplaces including offices, hospitals, manufacturing sites, and retailers, is so precise that it is able to provide records of employees’ device names, together with the exact enter and exit times and duration of visits between “zones” in offices—including one labeled “break area/kitchen” in a demo. Yikes.

For each of these systems, a range of different applications is functionally possible, and some which raise labor-law concerns. “A worst-case scenario would be that management wants to fire someone and then starts looking into historical records trying to find some misconduct,” says Christl. "If it’s necessary to investigate employees, then there should be a procedure where, for example, a worker representative is looking into the fine-grained behavioral data together with management. This would be another safeguard to prevent misuse.”

Above and Beyond?

If warehouse-style tracking has the potential for management overkill in office settings, it makes even less sense in service and health care jobs, and American unions are now pushing for more access to data and quotas used in disciplinary action. Elizabeth Anderson, professor of public philosophy at the University of Michigan and the author of Private Government: How Employers Rule Our Lives, describes how black-box algorithm-driven management and monitoring affects not just the day-to-day of nursing staff but also their sense of work and value.

“Surveillance and this idea of time theft, it’s all connected to this idea of wasting time,” she explains. “Essentially all relational work is considered inefficient. In a memory care unit, for example, the system will say how long to give a patient breakfast, how many minutes to get them dressed, and so forth.

“Maybe an Alzheimer’s patient is frightened, so a nurse has to spend some time calming them down, or perhaps they have lost some ability overnight. That’s not one of the discrete physical tasks that can be measured. Most of the job is helping that person cope with declining faculties; it takes time for that, for people to read your emotions and respond appropriately. What you get is massive moral injury with this notion of efficiency.”

This kind of monitoring extends to service workers, including servers in restaurants and cleaning staff, according to a 2023 Cracked Labs’ report into retail and hospitality. Software developed by Oracle is used to, among other applications, rate and rank servers based on speed, sales, timekeeping around breaks, and how many tips they receive. Similar Oracle software that monitors mobile workers such as housekeepers and cleaners in hotels uses a timer for app-based micromanagement—for instance, “you have two minutes for this room, and there are four tasks.”

As Christl explains, this simply doesn’t work in practice. “People have to struggle to combine what they really do with this kind of rigid, digital system. And it’s not easy to standardize work like talking to patients and other kinds of affective work, like how friendly you are as a waiter. This is a major problem. These systems cannot represent the work that is being done accurately.”

But can knowledge work done in offices ever be effectively measured and assessed either? In an episode of his podcast in January, host Ezra Klein battled his own feelings about having many of his best creative ideas at a café down the street from where he lives rather than in The New York Times’ Manhattan offices. Anderson agrees that creativity often has to find its own path.

“Say there’s a webcam tracking your eyes to make sure you’re looking at the screen,” she says. “We know that daydreaming a little can actually help people come up with creative ideas. Just letting your mind wander is incredibly useful for productivity overall, but that requires some time looking around or out the window. The software connected to your camera is saying you’re off-duty—that you’re wasting time. Nobody’s mind can keep concentrated for the whole work day, but you don’t even want that from a productivity point of view.”

Even for roles where it might make more methodological sense to track discrete physical tasks, there can be negative consequences of nonstop monitoring. Anderson points to a scene in Erik Gandini’s 2023 documentary After Work that shows an Amazon delivery driver who is monitored, via camera, for their driving, delivery quotas, and even getting dinged for using Spotify in the van.

“It’s very tightly regulated and super, super intrusive, and it’s all based on distrust as the starting point,” she says. “What these tech bros don’t understand is that if you install surveillance technology, which is all about distrusting the workers, there is a deep feature of human psychology that is reciprocity. If you don’t trust me, I’m not going to trust you. You think an employee who doesn’t trust the boss is going to be working with the same enthusiasm? I don’t think so.”

Trust Issues

The fixes, then, might be in the leadership itself, not more data dashboards. “Our research shows that excessive monitoring in the workplace can damage trust, have a negative impact on morale, and cause stress and anxiety,” says Hayfa Mohdzaini, senior policy and practice adviser for technology at the CIPD, the UK’s professional body for HR, learning, and development. “Employers might achieve better productivity by investing in line manager training and ensuring employees feel supported with reasonable expectations around office attendance and manageable workloads.”

A 2023 Pew Research study found that 56 percent of US workers were opposed to the use of AI to keep track of when employees were at their desks, and 61 percent were against tracking employees’ movements while they work.

This dropped to just 51 percent of workers who were opposed to recording work done on company computers, through the use of a kind of corporate “spyware” often accepted by staff in the private sector. As Josh Bersin puts it, “Yes, the company can read your emails” with platforms such as Teramind, even including “sentiment analysis” of employee messages.

Snooping on files, emails, and digital chats takes on new significance when it comes to government workers, though. New reporting from WIRED, based on conversations with employees at 13 federal agencies, reveals the extent to Elon Musk’s DOGE team’s surveillance: software including Google’s Gemini AI chatbot, a Dynatrace extension, and security tool Splunk have been added to government computers in recent weeks, and some people have felt they can’t speak freely on recorded and transcribed Microsoft Teams calls. Various agencies already use Everfox software and Dtex’s Intercept system, which generates individual risk scores for workers based on websites and files accessed.

Alongside mass layoffs and furloughs over the past four weeks, the so-called Department of Government Efficiency has also, according to CBS News and NPR reports, gone into multiple agencies in February with the theater and bombast of full X-ray security screenings replacing entry badges at Washington, DC, headquarters. That’s alongside managers telling staff that their logging in and out of devices, swiping in and out of workspaces, and all of their digital work chats will be “closely monitored” going forward.

“Maybe they’re trying to make a big deal out of it to scare people right now,” says Bersin. “The federal government is using back-to-work as an excuse to lay off a bunch of people.”

DOGE staff have reportedly even added keylogger software to government computers to track everything employees type, with staff concerned that anyone using keywords related to progressive thinking or "disloyalty” to Trump could be targeted—not to mention the security risks it introduces for those working on sensitive projects. As one worker told NPR, it feels “Soviet-style” and “Orwellian” with “nonstop monitoring.” Anderson describes the overall DOGE playbook as a series of “deeply intrusive invasions of privacy.”

Alternate Realities

But what protections are out there for employees? Certain states, such as New York and Illinois, do offer strong privacy protections against, for example, unnecessary biometric tracking in the private sector, and California’s Consumer Privacy Act covers workers as well as consumers. Overall, though, the lack of federal-level labor law in this area makes the US something of an alternate reality to what is legal in the UK and Europe.

The Electronic Communications Privacy Act in the US allows employee monitoring for legitimate business reasons and with the worker’s consent. In Europe, Algorithm Watch has made country analyses for workplace surveillance in the UK, Italy, Sweden, and Poland. To take one high-profile example of the stark difference: In early 2024, Serco was ordered by the UK's privacy watchdog, the Information Commissioner’s Office (ICO), to stop using face recognition and fingerprint scanning systems, designed by Shopworks, to track the time and attendance of 2,000 staff across 38 leisure centers around the country. This new guidance led to more companies reviewing or cutting the technology altogether, including Virgin Active, which pulled similar biometric employee monitoring systems from 30-plus sites.

Despite a lack of comprehensive privacy rights in the US, though, worker protest, union organizing, and media coverage can provide a firewall against some office surveillance schemes. Unions such as the Service Employees International Union are pushing for laws to protect workers from black-box algorithms dictating the pace of output.

In December, Boeing scrapped a pilot of employee monitoring at offices in Missouri and Washington, which was based on a system of infrared motion sensors and VuSensor cameras installed in ceilings, made by Ohio-based Avuity. The U-turn came after a Boeing employee leaked an internal PowerPoint presentation on the occupancy- and headcount-tracking technology to The Seattle Times. In a matter of weeks, Boeing confirmed that managers would remove all the sensors that had been installed to date.

Under-desk sensors, in particular, have received high-profile backlash, perhaps because they are such an obvious piece of surveillance hardware rather than simply software designed to record work done on company machines. In the fall of 2022, students at Northeastern University hacked and removed under-desk sensors produced by EnOcean, offering “presence detection” and “people counting,” that had been installed in the school’s Interdisciplinary Science & Engineering Complex. The university provost eventually informed students that the department had planned to use the sensors with the Spaceti platform to optimize desk usage.

OccupEye (now owned by FM: Systems), another type of under-desk heat and motion sensor, received a similar reaction from staff at Barclays Bank and The Telegraph newspaper in London, with employees protesting and, in some cases, physically removing the devices that tracked the time they spent away from their desks.

Despite the fallout, Barclays later faced a $1.1 billion fine from the ICO when it was found to have deployed Sapience’s employee monitoring software in its offices, with the ability to single out and track individual employees. Perhaps unsurprisingly in the current climate, that same software company now offers “lightweight device-level technology” to monitor return-to-office policy compliance, with a dashboard breaking employee location down by office versus remote for specific departments and teams.

According to Elizabeth Anderson’s latest book Hijacked, while workplace surveillance culture and the obsession with measuring employee efficiency might feel relatively new, it can actually be traced back to the invention of the “work ethic” by the Puritans in the 16th and 17th centuries.

“They thought you should be working super hard; you shouldn’t be idling around when you should be in work,” she says. “You can see some elements there that can be developed into a pretty hostile stance toward workers. The Puritans were obsessed with not wasting time. It was about gaining assurance of salvation through your behavior. With the Industrial Revolution, the ‘no wasting time’ became a profit-maximizing strategy. Now you’re at work 24/7 because they can get you on email.”

Some key components of the original work ethic, though, have been skewed or lost over time. The Puritans also had strict constraints on what duties employers had toward their workers: paying a living wage and providing safe and healthy working conditions.

“You couldn’t just rule them tyrannically, or so they said. You had to treat them as your fellow Christians, with dignity and respect. In many ways the original work ethic was an ethic which uplifted workers.”
