Access PC/SC-compliant tags (ISO 14443-4)
All ISO 14443-4 compliant cards (PICCs) understand the ISO 7816-4 APDUs. The ACM1281U-C7
reader will only need to communicate with the ISO 14443-4 compliant cards through exchanging ISO
7816-4 APDUs and responses. ACM1281U-C7 will handle the ISO 14443 Parts 1-4 Protocols
internally.
The MIFARE 1K, 4K, Mini and Ultralight tags are supported through the T=CL emulation. Simply treat
the MIFARE tags as standard ISO 14443-4 tags. For more information, see

Where:

= 90 00h means the operation was completed successfully.
= 63 00h means the operation failed.
Typical sequence may be:
1. Present the tag and connect the PICC Interface.
2. Read/Update the memory of the tag.
Step 1:
Connect the tag.
The ATR of the tag is 3B 88 80 01
00 00 00 00
33 81 81
00 3Ah
In which,
The Application Data of ATQB = 00 00 00 00h,
protocol information of ATQB = 33 81 81h.
It is an ISO
14443-4 Type B tag.
Step 2:
Send an APDU, Get Challenge.
<< 00 84 00 00 08h
>> 1A F7 F3 1B CD 2B A9 58 [90 00h]
Note: For ISO 14443-
4 Type A tags, the ATS can be obtained by using the APDU “FF CA 01 00 00h.”
Example:
ISO 7816-4 APDU
To read 8 bytes from an ISO 14443-4 Type B PICC (ST19XR08E)
APDU = { 80 B2 80 00 08h }
Class = 80h; INS = B2h; P1 = 80h; P2 = 00h;
Lc
= None; Data In = None; Le = 08h
Answer: 00 01 02 03 04 05 06 07 [$90 00h]
