  • Page 4: Introduction

    1.0. Introduction The ACR122L serial protocol defines the interface between the PC and reader, as well as the communication channel between the PC and the supported contactless tags/cards – ISO 14443-4 Type A and B, Mifare, ISO 18092 (NFC), and FeliCa. The major applications supported are the following: Access Control, Identification: Reading the serial numbers of all cards in the field.

  • Page 8: Serial Interface (Ccid-Like Frame Format)

    4.0. Serial Interface (CCID-like Frame Format) In normal operation, the ACR122L acts as a slave device with regard to the communication between a computer and the reader. The communication is carried out in the form of successive command- response exchanges. The computer transmits a command to the reader, and then receives a response from the reader after the command has been executed.
