NFC (Near-field communication) is a communication protocol that allows two devices to communicate with each other within a short distance. In our daily lives, NFC is used in everything from mobile payments to access control cards and transportation cards.

BMC11T001 supports three protocols: ISO14443A, ISO14443B and ISO15693. You can choose the communication protocol based on the distance requirements of your application.

1. ISO14443A and ISO14443B are suitable for secure data transmission in a short distance, such as mobile payments and access cards.
2. ISO15693 is suitable for secure data transmission long distances and is commonly applied in warehouse management.

The product can read and write Type 2 Tag, Mifare Tag and ST25TB512 Tag. We also provide the Crypto_M encryption and decryption function, which is compatible with Mifare Tag.
The product comes assembled with one S50 card (Mifare 1K).

You can insert the product into an Arduino UNO or the BMduino-UNO, BM53A367A, which is designed by Best Modules,. You don't need an external cable, just connect the shield to Arduino UNO or the BM53A367A.

Other pins are not used.
