• ISO 7816 Parts 1-4 Compliant for Contact Smart Card Interface.
• Support contact memory cards.
• ISO 14443 Parts 1-4 Compliant for Contactless Smart Card Interface.
• A built-in antenna for PICC contactless access applications.
• The ACR1281 supports the following Tag Types:
o MIFARE Classic. E.g. MIFARE 1K, 4K, MINI and Ultralight.
o ISO14443-4 Type A and B.
• T=CL emulation for MIFare 1K/4K PICCs. Multi-Blocks Transfer Mode is provided for
efficient PICC access.

• T=CL: Block-oriented asynchronous half duplex transmission protocol for PICCs (ISO
14443).
• APDU: Application Protocol Data Unit.
• ATR: Answer-to-Reset. The transmission sent by an ICC to the reader (IFD) in response to
a RESET condition.
• ATS: Answer-to-Select. The transmission sent by a PICC Type A to the reader (PCD) in
response to a SELECT condition.
• ATQB: Answer-to-Request. The transmission sent by a PICC Type B to the reader (PCD)
in response to a REQUEST condition.
• Card Insertion Event: Either an ICC or a PICC is just appeared to the reader.
•
Card Removal Event: Either an ICC or a PICC is removed from the reader.
• NAK: Negative Acknowledge, only used to get the last response or slot change message
report in ACR1281S.
• XOR : Exclusive OR
• RDR: ACR1281S.
• HOST: Host Controller.
• HOST_to_RDR: Host Controller -> ACR1281S
• RDR_to_HOST: ACR1281S -> Host Controlle
