The NFC Tag Click Board™ is an accessory add-on board from MikroElektronika carrying an M24SR64 NFC/RFID tag IC with a dual interface. It is embedded with a highly reliable 8KB EEPROM memory. The user can operate NFC Tag Click Board™ in three different ways: via I2C interface, with a 13.56MHz RFID reader, and with an NFC-enabled smartphone, tablet, or similar device. The RF protocol is compatible with both NFC Forum Type 4 Tag and ISO/IEC 14443 Type-A. The Click Board™ communicates with the target board microcontroller using MikroBUS I2C (SCL, SDA), INT and RST lines.
The NFC (Near Field Communications) Tag Click Board™ features a PCB antenna that operates at a very close range (around 3cm), which makes it quite secure for developing mobile payment systems (some credit cards, Apple Pay, Google Wallet, etc.), or any short-range wireless data exchange. NFC Tag Click Board™ is designed to use a 3.3V power supply only.
