Near Field Communication (NFC) is a wireless technology that allows data to be exchanged between two different devices -- say, a cellphone and a credit card terminal -- from a short distance away. If your phone has NFC, when you hold it near a properly equipped terminal, the phone and the terminal communicate. The terminal in turn communicates with a remote computer to approve payment.
