**5.4 Peer to peer mode**

In peer-to-peer mode, two NFC specific devices can exchange data such as, pairing Bluetooth devices or WiFi link set-up, exchange business cards or text messages. This mode is standardized on the ISO/IEC 18092 NFCIP-1 standards. Both the devices operate in active mode during the communication and data is sent over a bi-directional half duplex channel, which means second device can only transmit data once first NFC device finish the transmission [14].
