A growing number of smartphones and tablets are incorporating NFC chips so that you can wireless communicate with devices. You may be wondering, "why do I need NFC if I already have Wi-Fi and Bluetooth?"
NFC requires no pairing. It's low-power. It's effortless. You've probably seen the commercials on television where people are holding phones only a few centimeters apart to share information. NFC is based on radio-frequency identification (RFID) standards.
NFC can be used to share contacts, photos, videos or other files.
NFC can be used to store and share patient data securely.
NFC can be used in contactless payment systems. You won't need to carry a wallet soon.
NFC devices can act as electronic identity documents and keycards. Single-sign-on. Secure touch-and-go login. Touchless sign-on. Secure authentication.
There are a growing number of ways that NFC can be used in health care. The next time you shop for a new phone or tablet, check to see if it has NFC. Over the next few years, NFC will probably become a standard feature that we'll see on almost every mobile device. It won't replace Wi-Fi or Bluetooth because it will be used for other types of applications.
