8.1. How to Access PCSC-Compliant Tags (ISO 14443-4)?
Basically, all ISO 14443-4 compliant cards (PICCs) would understand the ISO 7816-4 APDUs. The
AET62 Reader just has to communicate with the ISO 14443-4 compliant cards through exchanging
ISO 7816-4 APDUs and Responses. AET62 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 ISO 14443-4 tags. For more information, please refer to topic “PICC
Commands for Mifare Classic Memory Tags”.
