Small Data ExchangeΒΆ

NFC isn’t a fast data carrier - it’s beauty lies in the explicitness of interaction that a user conciously performs when touching two devices. But 424 kbps physical speed and a transmit time of about 1 second are good enough to transfer about 20 kilobyte of user data with the Simple NDEF Exchange Protocol (SNEP) or other protocols that run on top of the Logical Link Control Protocol (LLCP).
