How NFC Tags Work

nfc chip

NFC technology enables simple and safe two-way interactions between electronic devices, allowing consumers to perform contact less transactions, access digital content, and connect electronic devices with a single touch. NFC complements many popular consumer level wireless technologies, by utilizing the key elements in existing standards for contactless card technology An NFC chip operates as one part of a wireless link. Once  it’s activated by another chip, small amounts of data  between the two devices can be transferred when held a  few centimeters from each other. Near field communication is  fast and easy. NFC can be compatible with existing contactless card infrastructure and it enables a consumer to utilize one device across different systems.

Extending the capability of  contactless card technology, NFC also enables devices to share information at a distance that is less than 4 centimeters with a maximum communication speed of 424 kbps. Users can share business cards, make transactions, access information from a smart poster or provide credentials for access control systems with a simple touch. NFC’s bidirectional communication ability is ideal for establishing connections with other technologies by the simplicity of touch. For example, if a user wants to connect a mobile device to a stereo system to play music, he can simply touch the device to the stereo’s NFC touch point and the devices will negotiate the best wireless technology to use.
