1. How to access PCSC Compliant Tags (ISO14443-4)?
Basically, all ISO 14443-4 complaint cards (PICCs) would understand the ISO 7816-4 APDUs.
The ACR1281S Reader just has to communicate with the ISO 14443-4 complaint cards through
exchanging ISO 7816-4 APDUs and Responses. ACR1281S will handle the ISO 14443 Parts 1-4
Protocols internally.
MIFARE 1K, 4K, MINI and Ultralight tags are supported through the T=CL emulation. Just simply
treat the MIFARE tags as standard ISO14443-4 tags. For more information, please refer to topic
“PICC Commands for MIFARE Classic Memory Tags”
