: MIFARE 4K Memory Map
Example 1:
To authenticate Block
04h
with the following characteristics: Key A, key number
00h
, from PC/SC
V2.01 (Obsolete).
APDU = { FF 88 00
04
60
00h
}
Example 2:
Similar to the previous example, to authenticate Block
04h
with the following characteristics: Key A,
key number
00h
, from PC/SC V2.07.
APDU = { FF 86 00 00 05 01 00
04
60
00h
}
Note: MIFARE® Ultralight does not need authentication since it provides free access to the user data
area.
