This is provided by specified Key A and Key B, and the defined sector trailer for each card block. To create a new card with the same content, you can use the same Keys and settings as for the “original”, but you can also define the custom authentication for every card, or for the part of the copied content. If you find it difficult to enter the card content through this interface, you may use any other Digital Logic tool for card writing, and then just read the content, store it into the file or use it for new card programming. Whether you’re writing or reading a card, all user-defined content will be displayed in the fields under the read line. Let’s now move to the other writable parts of the card memory. This data can be read and saved into some log file, but you cannot edit or clone the card UID (at least, not legally). Unlike other sectors that contain 3 blocks and 16bytes, Sector 0 has only 2 blocks, the zero block with card UID, and the block with the manufacturer data (all read-only). Depending on the card series, the first 4 or 7 bytes contain the card UID. The empty card content and structure interface looks like this:Īt the top left, the card content s displayed, and in this case, the entire card memory is blank, except ic factory UID stored in the first card block (block 0). This means that all other readers (without a valid Security Key) will not be able to access the card data. Also, with this software, you can define the additional security by assigning the Reader Key for the programmed cards. For each memory block, you can definable the custom access conditions. As for the rest of the card memory, it comes completely blank and access-free.

The first block (block zero) contains the card factory UID, ad it is read-only by default.
