NFC on a Work Tablet: What It Is Actually For

NFC is one of those lines on a spec sheet that nobody asks about and almost nobody uses on purpose. Every device in our range lists it, from the Tuga A6 at £349 to the Tuga W10 at £649. The short answer: NFC lets a tablet or handheld read a small tag by touching it, from a few centimetres away. That makes it useful for asset tags on plant, check-in points on a site and tapping a tag to open the right job or procedure. It is not a barcode scanner, and it is not the long range RFID used in warehouses. If your work never involves tagged equipment or fixed locations, you can ignore it and lose nothing.

What NFC Is

NFC stands for near field communication. It is a short range radio link that works over a few centimetres at most. The reader in the device powers a passive tag through the air, and the tag sends back a small amount of data, usually a serial number, a short text string or a web address. The tag has no battery. It is a coil of wire and a tiny chip inside a sticker, a plastic disc, a keyfob or a hard housing, and it can sit on a machine for years until a reader touches it.

If you have paid by tapping a bank card or a phone on a terminal, you have used NFC. Contactless payment is the same technology at the same frequency, 13.56MHz. The W10 lists that figure in its specs; the other models list NFC without one, and NFC is a single standard, so a tag that works on one will work on the others.

The short range is the point. You have to put the device on the tag, so there is no reading the wrong one from across the room and no doubt about which asset you meant.

What NFC Is Not

Three things get confused with NFC, and the confusion leads to buying the wrong device.

It Is Not a Barcode Scanner

A barcode is printed and read by light. An NFC tag is a chip and read by radio. Barcodes are cheap in volume, every box in a supply chain already has one, and a scanner reads them from arm's length. NFC tags cost more each, have to be fitted to each item, and are read by touch.

If your work is stock, parts and deliveries, you want a barcode scanner. On Android that is the A6, with its built-in Zebra 2D scan engine and two side scan keys. On Windows, the scanner versions of the Tuga WH6 (£779), the Tuga W8 (£699) and the Tuga W10 (£729) add a 2D engine to the standard model. Our guide to whether you need a built-in barcode scanner covers the camera versus Bluetooth scanner versus built-in choice in full. NFC does not replace any of those.

It Is Not Long Range RFID

RFID is a family of technologies, and NFC is its short range member. The other one you will hear about is UHF RFID, which reads tags from a metre or more away and can read many tags in one sweep. That is what counts a pallet of tagged boxes without opening it, or finds a tool in a van without unloading it. It needs a dedicated reader with its own antenna, and tags built for it.

In our range, only the W10 with 2D Scanner lists UHF RFID, and as an option. Everything else reads NFC and nothing more. If a supplier or a job description mentions RFID, ask which kind they mean before you assume a tablet with NFC on the spec sheet will do it.

It Is Not a Location System

NFC does not track where a device or a tag is. The device only knows it touched a tag, at the moment it touched it. For location you want GPS, which the A6, A8, A10, WH6 and W8 list as standard and the W10 as an option. The two work well together: an app can record a tag read alongside a GPS position and a timestamp.

What It Is Actually For on Site

None of these uses needs hardware beyond the tag itself. Many job management and maintenance apps read NFC tags, but check yours on the device first.

Asset Tags on Plant and Equipment

Fix a tag to a boiler, a pump, a distribution board, a lift motor or a generator. When an engineer arrives, they touch the device to the tag and the app opens that asset's record: its history, the last service, the open faults, the manual. No searching a list of similar pumps for the right one and no typing a serial number off a plate that is rusted or behind the unit.

Tags survive where printed labels do not. A barcode label in a plant room fades, gets painted over or peels off in the damp. An NFC tag in a hard housing sits behind the paint and still reads, and it reads in a dark corner where a camera would struggle to focus.

This is the main reason facilities and maintenance teams care about NFC. Our guide to rugged tablets for facilities and maintenance teams goes into the wider setup, and the CMMS and maintenance apps on our works with pages list what each vendor publishes about tag reading.

Check-in Points

Put a tag at the gate of a site, at the door of each plant room, or at each stop on a security or cleaning round. Touching the tag records that someone was at that point at that time. It is harder to fake than a tick box and quicker than a signature. For lone workers, and for firms that have to show a client a visit happened, a tag read, a timestamp and a photo together make a record that holds up.

Opening the Right Job or Procedure

A tag can hold a short web address or a reference that an app recognises. Touch the device to the tag on a machine and the app opens the start-up procedure for that machine, the isolation checklist or the risk assessment for that area. For a team with shared devices and staff who rotate between sites, that puts the right document in front of the person stood at the equipment.

What Tags Cost and How to Fit Them

We do not sell NFC tags, and prices vary with quantity, housing and chip memory, so we will not quote a figure. In general terms: a plain sticker tag is cheap enough to put on every item, a tag in a hard housing rated for outdoor or industrial use costs more but lasts years, and a tag built to be read on a metal surface costs more again. That last point matters. A standard tag stuck directly on a steel cabinet or a pump casing may not read at all, because the metal interferes with the radio field. Look for tags described as on-metal or anti-metal for anything you are fixing to plant.

Fitting is simple. Clean the surface, stick or screw the tag on, then write the asset reference to it with your app or a free tag writing tool, or record the tag's own serial number against the asset. Place tags where someone can touch the back of a tablet to them without climbing or reaching into a live enclosure. The tag needs to be reachable, not just visible.

Reading a Tag with a Rugged Tablet

The NFC antenna sits in the back of the device, so you touch the back of the tablet to the tag, not the screen. On a 10 inch tablet that is a two handed job. On the 277g A6 or the 470g WH6 it is a one handed one, and both fit the Belt Holster (£22) on our accessories page so the device is to hand between tags on a walk round.

A thick cover on the back can reduce the read range or stop it altogether, so if you add a third party back cover, test a tag read with it fitted. Our Tempered Glass Screen Protector (£14 for two) goes on the front and makes no difference. Neither do gloves, because there is nothing to press.

Which Tuga Device for NFC Work

Every model reads NFC, so this is a question about the rest of the job.

• Tuga A6, £349. A 6 inch Android 15 handheld at 277g with a built-in 2D barcode scanner. The one for walk rounds where you touch tags and scan barcodes all day. IP67, rated for 1.5 metre drops, removable 5050mAh battery.
• Tuga A8, £379. An 8 inch Android 12 tablet with a 1000 nit screen and a removable 8000mAh battery. Enough screen for a work order and the asset history side by side. Check your app supports Android 12.
• Tuga A10, £449. A 10.1 inch Full HD Android 14 tablet, IP68 and MIL-STD-810H, 680g. For manuals and drawings at the asset once the tag has opened them.
• Tuga WH6, £699. A 6.5 inch Windows 11 IoT handheld at 470g. For maintenance systems that only run on Windows, carried in a holster.
• Tuga W8, £629, and Tuga W10, £649. Windows 11 Pro tablets with USB-A and HDMI, and Ethernet on the W10, for engineers who plug into the plant as well as tap its tag. The W10 is the only model that can add a UHF RFID reader, as an option on the scanner version.

If you are not sure which size suits the work, the Which Tuga? picker asks four questions and points at one. Prices are as listed, with no VAT to add. Every device comes with a 12 month warranty, and delivery is free to UK addresses in 7 to 10 working days.

Should NFC Change Your Decision?

No. It is on every device we sell and on most phones, so it is not a reason to pick one Tuga over another, or a rugged device over the phone in your pocket. What matters is whether you will use it. If you maintain or inspect fixed equipment, visit the same locations repeatedly, or run shared devices across a team, NFC tags are a cheap way to make every record start in the right place. Set it up on one site, see whether the engineers actually tap the tags, and roll it out from there. If your work is stock and deliveries, put the money into a barcode scanner instead. And if someone promises a tablet that reads tags across a warehouse, ask whether they mean UHF RFID, because an NFC spec line will not do it.
