NFC RFID PN532 controller breakout board
Imagine having different users with different user levels for your system. You can filter them out by adding RFID based access control.
This module uses the PN532 NFC chip, one of the commonly used on modern-day phones that have NFC. It can do reading from and writing to 13.56MHz NFC/RFID cards or tags. It can serve as communication with phones, especially with payment processing. Inversely, it could also work like an NFC tag.
What's good with this module is that you can interface this with your Arduino using different ways, may it be using UART at any baud rate, SPI or I2C. The LIBNFC also supports it so that you can integrate this with your desktop projects using FTDI serial to USB converter.
The package includes headers as well as one RFID card and one RFID keychain tag.
