For RFID Cards with the UID format defined in the ISO standard ISO15693, the identifier for the card type is ISO15693. The value is formatted as specified in the ISO 15693 standard, a 64-bit unique identifier with the most significant bytes first. The value is represented as a hexadecimal string.
For card identifiers not defined in a widely accepted standard, the identifier for the type can be set to the domain name of the home institution that generated the number (local identifier).
