But you may not know what NFC is, the uses for it, or why we should actually care.

What is NFC?

NFC stands for Near-Field Communication and allows phones, tablets, and laptops to share data with other NFC-equipped devices. The technology evolved from radio-frequency identification (RFID) tech. RFID is behind those security scan cards that get you into the office every day or bypass that tollbooth on your morning commute.

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 of the reasons that NFC is taking off as a secure alternative to credit cards. The technology can be used for more than making purchases at Bloomingdales, however. NFC can transfer data like videos, contact information, and photos between two NFC-enabled devices.
