What Is an NFC Tag? A Simple Guide for Small Business Owners
You have probably heard the term NFC without knowing exactly what it means. Maybe you saw it mentioned on a loyalty app, or a supplier talked about NFC tags for your business. If you are a small business owner who is not particularly technical, this guide explains everything in plain English.
NFC stands for Near Field Communication. An NFC tag is a small, thin chip (usually the size of a coin or credit card) that communicates wirelessly with a smartphone when the two are held close together. No batteries, no charging, no internet connection required. The phone powers the tag during the brief interaction.
You already use NFC every day, even if you do not realise it. Every time you tap your bank card on a payment terminal, that is NFC. Every time you use Apple Pay or Google Pay with your phone, that is NFC. The technology is the same. The only difference is what information gets exchanged.
TL;DR
- NFC tags are small, battery-free chips that communicate with smartphones via a quick tap
- You already use NFC every day (contactless payments)
- For small businesses, NFC tags are most commonly used for loyalty stamp collection, marketing, and product information
- Tags cost a few pounds each and last indefinitely with no maintenance

How NFC Tags Work (The Simple Version)
An NFC tag contains a tiny antenna and a small chip with stored data. When you hold an NFC-enabled phone within a few centimetres of the tag, the phone's NFC reader powers the tag and reads the data. This happens in under a second.
The data on the tag can be almost anything: a website URL, a unique identifier, a text string, or a loyalty stamp instruction. The tag itself does not do the clever work. It simply tells the phone "here is my data," and the phone's app decides what to do with it.
Key facts:
- NFC works within 1-4 centimetres (you need to be close, which is by design)
- The interaction takes under a second
- Tags do not need batteries or charging (they are powered by the phone's signal)
- Tags are rewritable (the data can be changed) or locked (permanently fixed)
- Tags last indefinitely because they have no moving parts or power source
What Do NFC Tags Look Like?
NFC tags come in several forms:
Stickers and discs. Small, round adhesive stickers (about the size of a £1 coin) that can be stuck onto any surface. These are the most common form.
Cards. Credit-card-sized plastic cards with an embedded NFC chip. Your contactless bank card is essentially an NFC card.
Keyrings and wristbands. NFC chips embedded in wearable accessories. Common in festivals and gyms.
Custom-branded tags. Tags printed with a business logo, designed to look professional. These are what Lokaly provides for its loyalty programme: branded NFC discs that attach to retractable lanyards for staff to wear.
Regardless of form, the technology inside is identical. The only differences are durability, size, and how they are presented to customers.
How UK Small Businesses Use NFC Tags
Loyalty Stamp Collection
This is the most common and fastest-growing use of NFC in UK small businesses. Instead of paper punch cards, customers tap their phone on an NFC tag to collect a digital stamp.
With Lokaly, the NFC tag sits on a retractable lanyard worn by staff. When a customer finishes their coffee, haircut, or meal, they tap their phone on the tag. A stamp is collected in two seconds. No paper, no ink, no lost cards.
The staff-controlled model is critical: because the tag is on the staff member (not on the counter), only authorised stamps are awarded. This eliminates the fraud problem that affects QR-code and counter-based systems.

Marketing and Information
Some businesses use NFC tags on products, packaging, or displays to link customers to more information. Tap a tag on a wine bottle label and it opens a webpage with tasting notes. Tap a tag on a property listing and it opens the full details. This is less common in small businesses but growing.
Access and Payments
NFC is the technology behind contactless payments and many access control systems (key cards for offices, hotel rooms, gym access). As a small business owner, you benefit from this daily even if you do not manage the tags yourself.
NFC vs QR Codes: Which Is Better for Business?
Both NFC and QR codes let a phone interact with physical objects. But they work differently and have different strengths.
| Factor | NFC Tag | QR Code |
|---|---|---|
| Speed | ~1 second (tap) | 3-10 seconds (open camera, aim, scan) |
| Works in low light | Yes | No (camera needs to see the code) |
| Customer effort | Hold phone near tag | Open camera, align, wait |
| Fraud risk (loyalty) | Low (staff-controlled) | Higher (anyone can photograph) |
| Cost | A few pounds per tag | Free (print on paper) |
| Requires internet | No (device-to-device) | Usually yes |
| Familiarity | High (contactless payments) | High (post-COVID menus) |
For loyalty specifically, NFC is the stronger choice because of speed and fraud protection. For general marketing (linking to a website, sharing a menu), QR codes are cheaper and more widely understood.

What Do NFC Tags Cost?
Individual NFC tags cost between £0.50 and £3 each depending on quality, storage capacity, and form factor. Bulk orders bring the price down significantly.
With Lokaly, NFC tags are included in every plan at no extra charge:
- Starter (£5/month): 2 NFC tags
- Growth (£10/month): 5 NFC tags
- Power (£25/month): 10 NFC tags
You do not need to source, programme, or configure tags yourself. They arrive ready to use, pre-configured for your business, and attach to the retractable lanyards included with your plan.
Do All Phones Support NFC?
In 2026, the vast majority of smartphones support NFC:
iPhones: All models from iPhone 7 onwards (2016+) support NFC. That covers virtually every iPhone still in active use.
Android: Most Android phones from mid-range and above have supported NFC since 2015. Some very budget models (under £100) may not, but this is increasingly rare.
In practice, if your customer uses contactless payments on their phone, their phone supports NFC. The technology is the same.
Common Questions
"Do customers need to download an app?" For NFC loyalty with Lokaly, yes. Customers download the Lokaly app once, and every future stamp collection is a two-second tap. Because Lokaly works across multiple local businesses, your customer may already have the app from another shop.
"What happens if the tag gets damaged?" NFC tags are durable with no moving parts. They survive being dropped, washed, and general wear. If one does stop working, Lokaly replaces it.
"Can I reprogram the tag?" Lokaly tags are pre-configured for your business. You do not need to programme them yourself. If you need to change settings, it is done through the merchant portal.
"Is NFC secure?" Yes. The short range (1-4 centimetres) means someone cannot skim your tag from across the room. Each interaction generates a unique, encrypted, time-stamped transaction. For loyalty use, the staff-controlled model adds an additional layer of security.
