What is NFC? How It Works and What It Can Do
What is NFC?
NFC stands for Near Field Communication. It’s a short-range wireless technology that allows two devices to communicate when they are just a few centimetres apart, usually less than 4 cm.
If you’ve ever tapped your phone to pay for a coffee, shared a photo by bumping two phones together or used your phone to board a train, you’ve already used NFC without even realising it.
NFC is built on the same technology as RFID (Radio Frequency Identification), but it takes things a step further by enabling two-way communication between devices. This makes NFC extremely versatile and secure for a wide variety of everyday applications.
How does NFC work?
NFC works by using electromagnetic radio fields to enable communication between two NFC-enabled devices. Here’s a quick breakdown of how it functions:
- Passive devices: These are devices like NFC tags or smart cards that contain information but don’t have a power source of their own. They rely on the energy from an active device (like your smartphone) to operate.
- Active Devices: Devices like smartphones and payment terminals are active as they can send and receive information, and have their own power sources.
When two NFC devices are brought very close together, they establish a secure connection automatically. You don’t need to pair devices manually (like with Bluetooth) or even open an app. Just tap, and the devices communicate.
Because NFC operates over such a short distance, it’s also inherently more secure than longer-range wireless technologies.
What can NFC do?
Near Field Communication technology can be used for a wide range of practical, everyday tasks. Here are some of the most common uses:
- Contactless payments
One of the most popular uses of NFC is for contactless payments. With digital wallets you can simply tap your smartphone on a payment terminal to complete a transaction. It’s fast, easy and secure, thanks to tokenisation technology that protects your payment information.
- Sharing files
NFC can be used to share photos, videos, contacts and even app data between devices. While apps like Android Beam have been phased out in favour of faster file-sharing options like Nearby Share, NFC still plays a role in quickly establishing connections between devices.
- Smart access and ticketing
NFC technology is widely used for access control systems, allowing smartphones to replace physical keys or ID cards. It’s also commonly used in public transportation systems for tap-and-go ticketing, making commuting faster and more convenient.
- Pairing devices
Instead of dealing with complicated Bluetooth pairing processes, NFC can streamline it. For example, you can tap your phone to an NFC-enabled speaker or headphones to establish a connection instantly.
- Smart tags and automation
NFC tags are small, inexpensive chips that you can program to perform specific tasks when your phone touches them. For instance, you could have an NFC tag by your bedside that automatically silences your phone, sets an alarm, and turns off your lights – all with a simple tap.

Motorola continues to expand its lineup, offering even more choices for consumers who want to make the most of Near Field Communication.
Is NFC safe to use?
Security is a top concern whenever wireless communication is involved, but NFC has several built-in advantages:
- Short range: Since devices must be extremely close to communicate, it’s very difficult for hackers to intercept signals.
- Encryption: Many NFC transactions are encrypted, especially those involving financial information.
- Tokenisation: Payment systems often use tokenisation to create a one-time-use code rather than transmitting your actual card details.
With a motorola NFC phone, you can feel confident using NFC for payments, access and other daily tasks.
