Detailed Description

This class provides easy way to handle Mifare Classic access bits. Access bits are used to control accessibility of blocks on a Mifare Classic tag.

Detailed description of access conditions and bit combinations can be found from Mifare Standard Card Data sheets.

For Mifare Classic 1k, take reference from MF1ICS50 FS Sector 6.7 Memory access for access conditions. Table 3. describes access conditions for the sector trailer and Table 4. describes access conditions for data blocks.

For Mifare Classic 4k, take reference from MF1ICS70 FS Sector 6.7 Memory access for access conditions. Table 3. describes access conditions for the sector trailer and Table 4. describes access conditions for data blocks.
