Where:
Key Structure 1 byte.
00h = Key is loaded into the reader’s volatile memory.
Other = Reserved.
Key Number 1 byte.
00h ~ 01h = Key Location. The keys will be removed once the reader is
disconnected from the PC.

4.2.2. Authentication for MIFARE Classic 1K/4K
This command uses the keys stored in the reader to do authentication with the MIFARE 1K/4K card
(PICC). Two types of authentication keys used: TYPE_A and TYPE_B.
Load Authentication Keys APDU Format (6 bytes)
Command Class INS P1 P2 P3 Data In
Authentication FFh 88h 00h Block Number Key Type Key Number
Load Authentication Keys APDU Format (10 bytes)

Authenticate Data Bytes (5 bytes)
Byte1 Byte 2 Byte 3 Byte 4 Byte 5
Version 01h 00h Block Number Key Type Key Number
Where:
Block Number 1 Byte. This is the memory block to be authenticated.
Key Type 1 Byte.
60h = Key is used as a TYPE A key for authentication.
61h = Key is used as a TYPE B key for authentication.
Key Number 1 Byte.
00h ~ 01h = Key Location.
Note: For MIFARE Classic 1K Card, it has 16 sectors and each sector consists of 4
consecutive blocks. Ex. Sector 00 consists of Blocks {00h, 01h, 02h and 03h}; Sector 01h
consists of Blocks {04h, 05h, 06h and 07h}; the last sector 0Fh consists of Blocks {3Ch, 3Dh,
3Eh and 3Fh}.
Once the authentication is done successfully, there is no need to do the authentication again
if the blocks to be accessed belong to the same sector. Please refer to the MIFARE Classic
1K/4K specification for more details.
