Near Field Communication (NFC) technology is a short range wireless connectivity technology designed for intuitive, simple and safe communication between electronic devices. Making life easier and more convenient for consumers around the world, TI's NFC devices can configure Wi-Fi and Bluetooth® technology sessions between devices without consumer interaction, share and interact with feature- and content-rich data such as coupons at point of sale, and allow consumer devices to easily exchange files and contacts. NFC allows the user to operate in reader/writer, peer-to-peer and emulation modes. Near Field Communication is based on existing contactless / RFID standards where loosely coupled inductive circuits share power and data across a few centimeters. It combines the protocols and expands the communication possibilities above the standard RFID reader/writer capability with peer-to-peer communication and card emulation. With Near Field Communication, TI allows users to take advantage of continuously evolving their features and applications.
