NFC tags simplify Wi-Fi and Bluetooth pairing

The NTAG21xF family from NXP is designed to enable simple, low cost pairing via NFC between a range of consumer electronics devices and mobile accessories.

The tags have an integrated field detection mode which switches on the accessory when it comes into contact with an NFC phone or mobile device, quickly enabling a simple 'tap to pair' connection. "With field detection to wake up the accessory, pairing is now intuitive and much easier," said NXP in a statement. "Users simply tap their phone to the accessory and pairing is complete." The devices have a large memory, are NFC Forum Tag 2 Type compliant and work with any NFC enabled phone.
