The ACR122 is a PC-linked Contactless Smart Card Reader/Writer used for accessing ISO14443-4 Type A and B,ISO 18092 or NFC,and FeliCa tags.The ACR122 is PCSC compliant so it is compatible with existing PCSC applications.Furthermore,the standard Microsoft CCID driver is used to simplify the driver installation.
The ACR122 serves as the intermediary device between the personal computer and the contactless tag via the USB interface. The reader carries out the command issued from the PC,whether the command is used in order to communicate with a contactless tag or control the device peripherals(LED or buzzer).
The ACR122 uses the PCSC APDUs for contactless tags following the PCSC Specification and makes use of pseudo APDUs in sending commands for ISO 18092 tags and controlling the device peripherals.
