5. Configure the "ThirdParty" data in the "Application" -> "Data handling" section as follows:
- Position on Card: Segement number of the user defined segment.
- Block Number: Number of the block of the user defined segment, which shall be read.
- Mask: The data, that are read from the data carrier from the defined block within the segment,
are combined with logical AND with this MASK value to dertermine, which value is
relevant for the compare with the Result value (see next field).
- Result: The result of the AND calculation of the read data and the Mask value are compared
with this Result value. If both values match, access is granted, else access is denied.
In the example above, the Mask value of "00000000FFFFFF000000…" means that the first 4 bytes of the read
data are not relevant (Mask value is entered in hex, i.e. 8 digits = 4 bytes with all bits set to "0") and then the
next 3 bytes are relevant ("FFFFFF" = 3 bytes with bits set to7 "1") and the following bytes are again not
relevant. This means that all data carriers, which have the information "M36” in ASCII or "4D3336" in hex value
at position 5 to 7 of the read data, have access permission.
