Describe the Near Field Communication (NFC) technology.
What will be an ideal response?
Near Field Communication (NFC) is a wireless technology that establishes a communication link between two NFC devices that are within 4 inches of each other. For example, when you tap your smart phone with that of your friend, the two phones can use NFC to exchange contact information. NFC can also be used to read an NFC tag, which is a small microchip that can be embedded in just about anything, including a key chain tag, printed flyer, or billboard. The NFC tag dispenses information to any NFC-enabled smart phone or other device that comes within 4 inches of the tag.
