Presentation Description

NFC is one of the latest wireless communication technologies. As a short-range wireless connectivity technology, NFC offers safe yet simple and intuitive communication between electronic devices. Users of NFC-enabled devices can simply point or touch their devices to other NFC-enabled elements in the environment to communicate with them, making application and data usage easy and convenient. With NFC technology, communication occurs when an NFC- compatible Device is brought within a few centimetres of another NFC device or an NFC Tag. The big advantage of the short transmission range is that it inhibits eavesdropping on NFC-enabled transactions. NFC technology opens up exciting new usage scenarios for mobile device.

conclusion:

conclusion Touch-driven approach is relatively accurate in inferring user intent. the usability of touch-driven interaction using NFC is better than QR code-based or voice-based interactions, since the touch action is intuitive, and can be detected quickly, requiring no pre-configuration or setup. In this way once the devices are linked up using NFC, they can exchange information using wireless protocols such as WiFi and GPRS remotely. 11
