What are near field communications? NFC payments guide

Do you have a smartphone? Ever paid for something with it? Then chances are you've used NFC technology. NFC, or Near Field Communication, is a way for our devices to communicate wirelessly when they're close together. It's the tech behind those quick and easy tap-and-go payments you probably use at retail and hospitality venues.

Key takeaways:

• What it is: NFC is short-range wireless tech that lets a phone, card, or wearable "talk" to a payment terminal with a single tap.
• Main advantage for businesses: Speed and convenience. Transactions take just a few seconds, cutting queues and improving customer experience.
• Before you start: Make sure you've got an NFC-compatible terminal integrated into your POS system. Without it, you can't accept contactless payments at all.

This complete guide will teach you everything you need to know about NFC technology, asking questions like how does NFC work, to how does it compare to other card payment technology. So let's get stuck in!

What is NFC technology?

To define NFC, meaning near-field communication technology, or NFC tags: NFCs are a short-range wireless technology that makes smartphones, tablets, wearables, payment cards, and other devices smarter by making connectivity easier.

With NFC, you can transfer information from one NFC device to another with a single touch, using the NFC data exchange format.

Before, you had to use chip & PIN/ swipe, or sign for your purchases. But now, with NFC mobile payments, you can pay using your phone, even if you don't have your card with you.

NFC technology has been a big hit with consumers. In fact, in 2025, the global NFC market was worth around $36.11 billion and it's expected to grow to around $125 billion by 2034.

What is near field communication used for?

Now that you have a decent understanding of what near field communications technology is, let's talk about places you've probably come across it, without even knowing.

• Mobile payments: Using services like Apple Pay, Google Pay, and Samsung Pay, your customer taps their phone on an NFC reader to pay for an item or service.
• Public transport: Ever tapped your Apple watch on a terminal to ride the bus, train, or tube? That's NFC!
• Access control: If you live in a modern high-rise that uses key cards to enter buildings, or if you're staying at a hotel, NFC-enabled key cards open doors.
• Sharing files: Sending photos or contacts between two NFC-enabled devices with a tap.
• Smart posters: Scanning posters with your phone for more information or special deals.
• Pairing devices: Quickly connecting Bluetooth devices like speakers or headphones.

These are just a few common examples. NFC technology is everywhere, making daily tasks quicker and easier.

Types of NFC enabled devices

We've touched on this briefly above, but what's an NFC device?

Well there are a lot of different types of electronic devices that have NFC built-in, including:

• Smartphones and mobile devices
• Tablets
• Smartwatches and other wearables
• Some laptops

All of them have NFC technology built in. This lets them talk to other NFC devices or tags wirelessly.

How do NFC mobile payments work?

As a business owner, there's a few steps you need to take to process NFC transactions at your retail or hospitality company.

First, you'll need NFC-enabled payment terminals or card machines integrated into your POS system at checkout. These terminals communicate with customers' devices when held close by. At Epos Now, all of our card readers do this.

The process itself is simple:

Tap (Held near reader)
Encrypt (Details encrypted)
Verify (Funds checked)
Confirm (Receipt sent)

The customer unlocks their device and holds it near the reader, which detects the NFC signal and opens a secure connection for payment processing. Payment details are encrypted in transit, preventing interception. The terminal then checks the POS transaction details against the payment gateway to confirm sufficient funds, and once approved, both customer and business receive confirmation.

Make sure your terminals meet current industry standards to safeguard customer data and prevent fraud. To improve the experience further, highlight the ease and safety of NFC payments to customers, train staff to assist where needed, and keep terminals updated with the latest security features.

Advantages and disadvantages of accepting NFC payments

If you're not already, you should definitely consider offering this payment option to your business. Here's why:

Advantages

• More secure: Mobile wallets like Apple Pay keep your bank details safe by scrambling them into something that fraudsters can't understand or use. Each time you make an NFC payment, new tokens are generated, making it really hard for anyone to steal your information. Apple Pay adds even more protection with fingerprint verification using Touch or Face ID, so only you can authorise payments with your unique fingerprint.
• Faster: You know those chip and PIN cards everyone has now? They're great for security, but they can be slow. EMV transactions, where the chip talks to the processor to check everything's okay, take time—especially when there's a line. NFC transactions are much quicker. They only take a few seconds. As more people realise how fast and easy contactless payments are compared to chip and PIN, businesses benefit from shorter queues and happier customers.
• More convenient: We're all used to doing everything on our phones nowadays. It's like our whole lives are in there. That's why NFC contactless payments are so convenient. You don't have to dig around for your wallet or deal with cash. Just tap your phone and you're done. It's the easiest way to pay, and more and more people are loving it for its simplicity. This is especially useful for customers with dexterity limitations.

Disadvantages

Now, it's not all sunshine and rainbows. There are a few things you'll need to think about before introducing NFC technology to your business. Here are some of the downsides that may come with offering an NFC tag:

• Cost: Implementing NFC technology is definitely an expense. Although it's worthwhile, you'll still need a budget to purchase compatible devices and set up infrastructure, all to ensure you meet compliance standards and maintain high financial security.
• Limited range: Because NFC only works over short distances, typically a few centimetres, it can restrict its use in certain applications.
• Low data transfer rate: Compared to other wireless technologies, NFC has slower data transfer rates, which may not be suitable for large file transfers or high-speed comms.

Appendix

Contactless payment limits exist to balance speed with fraud prevention, but they vary significantly by country and card issuer, so it's worth checking the rules where your business operates.

• Contactless limit: £100 per transaction, in place since October 2021. Although, as of March 2026, the FCA is allowing banks and payment providers with strong fraud controls to set their own limits, though most aren't expected to change immediately.
• PCI DSS compliance: PCI DSS v4.0.1 is now fully mandatory, with the transition grace period closed since March 2025. UK merchants must complete an annual Self-Assessment Questionnaire (or full audit for larger volumes), plus ongoing network security and access controls.
