MIFARE Classic (new/empty card)

The following parameters are determined during configuration:
- : MIFARE Classic or DESFire
- Card templates) : Card template (see
- The card template decides on:
- : must be available in free memory space on the card.
- AXM Classic automatically assigns lock IDs with LID 0-127 reserved for internal functions. : shows the number of possible locking device IDs for this card.
- See Cards and locking device IDs for background information.
- : shows the number of entries that can be written on this card’s physical access list. For AV templates only (Audit trail & Virtual network).
- : indicates whether a virtual network is possible. AV templates only.
The following is also determined for MIFARE Classic:
- SectList: List of sectors where the data from your locking system is stored.
- TransportSectorTrailer: Encryption of your locking system data on the card
- Card type: MIFARE Classic
- Read the card or consult the data sheet.
- Full report is displayed.
- Determine the available memory space or sectors (EXTRA # Memory size section).
- Card contains 16 sectors.
- Sector 0 is internal for MIFARE Classic and sector 1 should not be used, so there are 14 sectors available.
NOTE
Sector structure, card-specific
The sector structure may differ for your card. Cards with a larger memory in particular may have more master sectors (e.g. often sector 16) and have different sector sizes, i.e. more storage space per sector.
Even on new cards, the manufacturer may have blocked sectors and these must first be unblocked.
Example: MIFARE Classic EV1 4k: 4kB memory, divided into Sectors 0-31 with 4 blocks each and Sectors 32-39 with 16 blocks each. Sector 16 is another master sector here.
- Read the report carefully to determine master sectors and sector size.
- If you decide to have your card checked by SimonsVoss: Feel free to contact one of our sales representatives in your region.
- Each sector consists of three writeable blocks and one block for encryption: 3*16 bytes = 48 bytes per sector.
- Available sectors can be identified in the report by three blocks marked [rwi]: read/write/increment – the fourth block is for encryption.
- Internal card sectors can be identified in the report by the fact that not all three blocks are marked with [rwi]:
- Calculate the available storage space: Bytes per sector * available sectors (example: 48 bytes * 14 sectors = 672 bytes).
- From the drop-down menu , select .
- Consider whether you need a physical access list or a virtual network for your cards.
- If you do: You need an AV template (="Audit trail and “Virtual network”).
- Determine the largest card configuration that fits into the available memory (see Card templates – example for AV: MC1000L_AV with 528 bytes).
- Select the configuration you just specified from the drop-down menu (example: MC1000L_AV).
- shows the memory requirement on the card.
- AXM Classic automatically assigns lock IDs with LID 0-127 being reserved for internal functions). See Cards and locking device IDs for background information. shows the number of possible locking device IDs for this card (
- shows the number of possible entries in the physical access list (for AV templates only).
- The number of entries for locking devices in the matrix is limited to the number of possible locking device IDs. Locking devices can also consume more than one entry, e.g. freely rotating Digital Cylinder AX.
- The physical access list is overwritten on a rolling basis, so it is not limited.
- A virtual network is possible.
- Calculate the number of sectors actually needed: / bytes per sector (example: 528 bytes / 48 bytes = 11 sectors). Round off the result to the next integer if necessary.
- Click the button in the SectList field.
- The window will open.
- Enter as many free sectors as you need in the
Numbers separated by commas, without spaces. field (example: 2,3,4,5,6,7,8,9,10,11,12). Do not use sectors that are not writeable or used as a master sector (example: Sector 0 is not writeable and Sector 1 is a master sector). NOTE
Saved storage space thanks to own sector list
Obviously, you can also use the default sector list. However, it may even be the case that not all sectors from this list are used because the card configuration also fits into fewer sectors.
- Enter your own sector list.
- This allows you to save sectors on your cards that you might want to use for other applications in the future.
- Click on the button.
- window closes.
- Leave the TransportSectorTrailer field unchanged.
- TransportSectorTrailer is an integral part of card encryption. Your AXM Classic will automatically generate this entry for you.
- Click on the button.
- Window Locking system closes.
