Near-field communication is a wireless technology designed for short-range applications. It allows the phone to interact with devices or systems nearby. It may be used for biometric document verification, smart tag scanning, phone payments, and device pairing.

Near-field communication, or NFC, allows two suitable devices to be connected at a distance of around 4 cm. It is quicker and safer than Bluetooth or Wi-Fi.
The science behind near-field communication revolves around electromagnetic radio fields. When two NFC-enabled devices come close, they start a communication session. One device sends a signal, and the other responds instantly. That’s how NFC on phone can pay at a terminal or connect to another gadget.
Passive chips are found in cards that store data but don’t generate power to send it. Like those usually found in modern smartphones, active chips can read, write, and initiate connections. Phones typically use active near-field communication to both read and interact with passive tags.
Most modern phones, regardless of brand, have NFC. Smart devices like smartwatches with near-field communication for payments are also on the rise. Payment terminals, transit gates, and smart business cards are other examples.
Near-field communication is used in contactless payments, public transport, file sharing, smart marketing, secure access to buildings and cars, and even document verification. It adds speed and simplicity to many everyday interactions.
Apple Pay and Google Pay are the two most common apps that initiate payments. The idea behind these apps is to store your unique card token in the app (for security), which will act as a virtual key to your card without compromising safety. What is left for you to do is tap on an NFC terminal to pay. Because it’s instant, secure, and convenient, it is a growing technology worldwide
Many cities, including London, Brussels, and New York, use near-field communication for fast boarding. Offices use NFC-enabled badges for secure entry through doors or turnstiles.
NFC can instantly pair your phone with headphones or speakers with just one tap. You can also share files, contacts, or URLs between devices.
Enterprises use near-field communication in posters, business cards, and displays. A tap can open a website or app or save contact information. It’s an innovative, contactless way to engage people.
Thanks to this wireless technology, two devices may communicate across short distances. It instantaneously transfers tiny bits of data via radio waves.
Most modern smartphones do. Check your settings or the device's back for the NFC logo.
Near-field communication works within about 4 cm. For a successful session, the devices must be very close or almost touching.
Yes. It uses encrypted channels and tokenization. Most phones require a fingerprint, FaceID or passcode confirmation before completing an NFC payment.
Yes. You can share contacts, photos, or links using NFC-based sharing services suitable for your phone’s operating system.
