Smart cards based on MIFARE® Classic ICs are a commonly known solution in various applications such as: Access Control. Public Transportation. Electronic Toll CollectionMifare access bits calculator - link Online tool for calculating and parsing access conditions from sector trailers of Mifare Classic or Mifare Plus cards.

What The Access Bits In The MIFARE Classic Card Mean. Source: http://cache.nxp.com/documents/data_sheet/MF1S50YYX_V1.pdf. Example: SwissPass AC are set to 7F 07 88 00 for all sectors. As bits: The subscripts in the following table stand for which block they regard. The other bits are redundant. Sorted by blocks, we get this:

How to set the µFR Card Formatter software to configure the access bits and security keys for each sector of a MIFARE 1K card. Adjusting the RF analog registers on PN512 (DL533R) Windows PS/CS driver for µFR Series devices.There is a great app called MifareWnd that allows you to create costume Access bits by specifying the permissions in the program. Here is the link to the free mifareWnd: http://philips-semiconductors-mifarewnd.software.informer.com/1.7/ If you want be able to read all blocks with key A, write with key B, perform value block increments with key B and perform value block decrement, etc. with keys A and B, you could use access conditions like this:

A little ?useful? utility to encode/decode the sector trailer (block 3) bytes 6-7-8 (starting form 0; they are called "Access Bits"); those bits set the access conditions (read/write/value) of the 4 blocks of a specific sector.This online tool is for calculating and parsing access bits from sector trailers of Mifare Classic or Mifare Plus cards. It also demonstrates the possibilites of Qt for assembly.

To change them you have to authenticate the card with the correct access bits. Note: the Mifare key is composed as follow: 6 bytes for key A; 4 bytes for Access Bits; 6 bytes for key B which is optional and can be set to 00 or any other value.What The Access Bits In The MIFARE Classic Card Mean.
