Near Field Communication (NFC) is a method to wirelessly share information on your Samsung Galaxy Mega™. Use NFC to share contacts, websites, and images. You can even make purchases at locations that have NFC support. An NFC message appears automatically when your phone is within an inch of the target device.
NFC is a means of sending data over radio waves. In that sense it is similar to Wi-Fi or Bluetooth, but unlike those protocols (and like RFID) NFC can be used to induce electric currents within passive components as well as just send data. And it is faster than Bluetooth, in general. Indeed the two are closely linked, Samsung Beam uses NFC to pair devices, and then Bluetooth to transfer data.
NFC can work with passive devices that don’t require their own power supply, such as travel card readers. NFC’s data-transmission frequency is 13.56MHz. NFC can transmit data at either 106, 212 or 424 Kbps (kilobits per second).

NFC is not free from risk and the best way to protect yourself is to know what those risks are.
If your device has NFC you can download Credit Card Reader from the app store…
