ISO/TS 28560-4:2014 defines rules for ISO 28560‑1 data elements to be encoded in radio frequency identification (RFID) tags with a memory structure that is partitioned into four memory banks. This primarily applies to ISO/IEC 18000‑63 (previously known as ISO/IEC 18000‑6 Type C) operating in the UHF frequency, but not necessarily restricted to this technology.
The rules for encoding a subset of data elements taken from the total set of data elements defined in ISO 28560‑1 are based on ISO/IEC 15962, which uses an object identifier structure to identify data elements. This part of ISO 28560 defines the rules for encoding a unique item identifier in a specific memory bank, known as MB 01, taking into account different requirements for privacy. It also defines the rules for encoding other relevant data in a separate memory bank, known as MB 11. Each of these memory banks is addressable using different command set of the appropriate RFID technology.
