scope:

ISO/IEC 15963 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. Further discussion and explanation are given in Clause 5. 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.
