That small chip in your smartphone is capable of more than you might think. By learning how to use NFC on your smartphone, you can unlock a world of convenience, from making secure contactless payments to instantly sharing information. Near Field Communication (NFC) is a short-range wireless technology that allows two devices to communicate when they are brought close together, and it’s a standard feature on almost every modern phone.

💳 How to Set Up and Use Contactless Payments
The most popular use for NFC is for contactless payments. Services like Google Pay (on Android) and Apple Pay (on iPhone) use NFC to let you pay for things in a store by simply tapping your phone on the payment terminal. To set this up, you just need to open your phone’s wallet app and add your credit or debit card information. It’s incredibly secure because the transaction is encrypted and uses a one-time virtual card number, so your real card details are never shared with the merchant.
🏷️ How to Read NFC Tags for Instant Information
NFC is not just for payments; it can also be used to interact with NFC tags. These are small, unpowered chips that can be embedded in things like posters, business cards, or products. When you tap your phone on an NFC tag, it can trigger an action on your device, like opening a website, connecting to a Wi-Fi network, or showing you product information. It’s a fast and simple way to get digital information from a physical object.
🤝 How to Instantly Share Content with Other Phones
NFC also makes sharing content between two phones incredibly easy. On Android devices, a feature called Nearby Share can use NFC to initiate a connection. If you want to share a photo, a contact, or a webpage with a friend, you can simply open the content, touch your phones back-to-back, and you’ll get a prompt on your screen to ‘tap to beam’ the content to the other device. It’s a much faster and simpler way to share information than sending a text or an email.
