What is NFC?
NFC stands for near-field communication, and it allows phones, tablets, laptops, and other devices to share data with other NFC-equipped devices easily. It evolved from radio-frequency identification (RFID) technology. RFID is behind those security scan cards that get you into the office every day or bypass that tollbooth on your morning commute.
All of the latest smartphones are equipped with NFC technology. Whether you notice it or not, your phone is more than likely using NFC right now. But don’t fear — NFC uses minimal battery and processing power while offering a host of benefits that improve your device’s functionality.
Although it’s widely used in peer-to-peer payment and data transfer apps, NFC has many more applications that can make your life easier, like TAPiTAG. Read on to find out how you can fully take advantage of your phone’s NFC capability.
NFC is very much like RFID, but NFC is limited to communication within about four inches, which is why you have to hold your phone so close to the contactless reader if you’re using Apple Pay or Samsung Pay. Most people consider NFC’s small radius a major security benefit, and it’s one reason why NFC has taken off as a secure alternative to credit cards. The technology can be used for more than buying coffee at Starbucks, however. NFC can also transfer data like videos, contact information, and photos between two NFC-enabled devices.
How does NFC work?
Unlike Bluetooth, NFC doesn’t require any manual pairing or device discovery to transfer data. An NFC connection is automatically started when another NFC device enters into the previously specified four-inch range. Once in range, the two devices instantly communicate and send prompts to the user. There’s huge potential with NFC.
