NFC Smartphones and Accessories
An NFC-enabled device can operate in reader/writer and peer-to-peer mode, and may operate in card emulation mode. Typically NFC readers are embedded into smartphones and functionality can be turned on/off by user. Some NFC smartphones also support writing mode functionality which enables tag writing. Downloadable apps such as NXP TagWriter or Tagage help to create tags easily per NFC Forum classified use cases.

The sample identification distance is tested using a resolution of 5 mm. The sample is attached to a low dielectric support, and the identification distance is defined from the NFC handset antenna's optimal reading point. Low dielectric spacer layers 5 mm thick are used to increase the distance between the sample under testing and the NFC handset, in 5 mm graduations.

Wireless NFC accessories
Bluetooth pairing functionality can be initially established via an NFC tag. The NFC tag makes pairing easier than ever. A password or handshake protocol aren’t needed – just “touch and go”! Examples of NFC accessories include hands-free sets, speakers, mice, keyboards, headsets, computer monitors and games consoles.
USB readers are used in situations requiring a computer to be connected to NFC readers, such as point-of-sales services, ID recognition, loyalty applications, event registration and access control.
Typical contactless technology applications include micropayments, loyalty programs, automatic fare collection systems and physical access control.
