Short for Near Field Communication, NFC is a widely used technology around us. It's behind daily applications such as access control system and mobile payment system. NFC Shield features a highly integrated transceiver module PN532 which handles contactless communication at 13.56MHz. You can read and write a 13.56MHz tag with this shield or implement point to point data exchange with two NFC Shields.
NFC Shield provides all necessary circuitry for PN532 like 27.12Mhz crystal, power supply. It also breaks-out the I/O pins of PN532 for easy access. The communication between Arduino and NFC Shield is via SPI.
In this new version, we assign an independent PCB antenna which can easily stretch out of any enclosure you use, leaving more room for you to design the exterior of your project.
The PCB comes stuck on the shield, but you can easily peel it off.
Features:
- 5cm max effective range
- SPI pin saving interface
- Serves for contactless communication at 13.56MHz
- Support P2P communication
- Support ISO14443 Type A and Type B protocols
