ISO/IEC 15962:2022 pdf, Information technology — Radio frequency identification (RFID) for item management — Data protocol: data encoding rules and logical memory functions.
ISO/IEC 15962:2022 focuses on encoding the transfer syntax of the application commands defined in ISO/IEC 15961-1. 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.
