The data protocol used to exchange information in a radio frequency identification (RFID) system for item management is specified in ISO/IEC 15961 and in ISO/IEC 15962:2013. Both International Standards are required for a complete understanding of the data protocol in its entirety; but each focuses on one particular interface:
ISO/IEC 15961 addresses the interface with the application system.
ISO/IEC 15962:2013 deals with the processing of data and its presentation to the RF tag, and the initial processing of data captured from the RF tag.
ISO/IEC 15962:2013 focuses on encoding the transfer syntax, as defined in ISO/IEC 15961 according to the application commands defined in ISO/IEC 15961. The encodation is in a Logical Memory as a software analogue of the physical memory of the RFID tag being addressed by the interrogator.
defines the encoded structure of object identifiers;
specifies the data compaction rules that apply to the encoded data;
specifies a Precursor for encoding syntax features efficiently;
specifies formatting rules for the data, e.g. depending on whether a directory is used or not;
defines how application commands, e.g. to lock data, are transferred to the Tag Driver;
specifies processes associated with sensory information and the transfers to the Tag Driver;
defines other communication to the application.
