Encapsulating commands for RFID tags and RFID readers

摘要

Radio Frequency Identification (RFID) tags may receive one or more encapsulated commands within the payload of an encapsulating command from an RFID reader. An encapsulated command includes at least a command code and an instruction. A tag may store the encapsulated command(s) or the instruction portion of the encapsulated command(s) for later execution. A sequence of encapsulated commands may be contained within one encapsulating command or spread across multiple encapsulating commands. The sequence of encapsulated commands, or the sequence of instructions associated with the encapsulated commands, may form a program. The tag may execute the instructions or program upon receipt, upon a trigger event, serially or in parallel, and/or may modify the instructions or program by adjusting parameters. The tag may later be told by a reader to execute the instructions or program via another command which, in some cases, may be sent prior to tag singulation.
