UPDATE BINARY instruction
In the UPDATE BINARY command APDU,
P1 is the sector number. It must be
h
00 for PICCs that have only one sector,
P2 is the address of the (single) page to be written. Please refer to the chip's datasheet to
know how many pages could be addressed.
Since the size of a page is 4 bytes, Lc
must be 4, exactly.
Some pages may hold
- OTP (one-time-programming) bits,
- OTP (one-time-programming) bits,
- and/or lock bits that are intended to make the PICC memory read only.
Do not write on those pages without a good understanding of the consequences.

Mifare UltraLight C 3-DES authentication
The Mifare UltraLight C supports a 3-pass Triple-DES authentication feature.
Use the ENCAPSULATE instruction with P1=
Use the ENCAPSULATE instruction with P1=

SpringCard has developed the PCSC_MIFULC software library (available as source code and as
pre-compiled DLL in the SDK) to help working with Mifare UltraLight C cards without the need to
