ISO/IEC 15963:2004

ISO/IEC 15963:2004 describes numbering systems that are available for the identification of RF tags. A unique ID is required as part of the write operation to RFID tags. The unique ID guarantees that the information written to a tag is unambiguously written to the correct data carrier (tag). A unique ID is also required in many read situations where the contents of the tag are tied to a specific item and that item needs to be unambiguously identified. The unique ID may also be used for the traceability of the integrated circuit itself for quality control in their manufacturing process;for the traceability of the RF tag during its manufacturing process and along its lifetime;for the completion of the reading in a multi-antenna configuration; by the anti-collision mechanism, to inventory multiple tags in the reader's field of view;for the traceability of the item to which the RF tag is attached.
