Manufacturer: Description:In many applications, the card or tag manufacturer may choose to overwrite the serial number stored as an ID in page 0 with a specific ID value of their choosing. If so desired, the final ID value can then be locked to prevent further changes. If the ID is not locked, or if additional validation of the ID is required, the manufacturer may choose to hash or encrypt the ID, serial number and another fixed secret. The result can be stored as part of the ID or in one of the unused pages. On presentation of the card, reading of this validation entry and the serial number will permit validation of the ID number. |
