RFID readers with run commands

摘要

Radio Frequency Identification (RFID) readers may transmit one or more run commands specifying one or more programs for tag execution prior to tag singulation. A run command may encapsulate the program(s), in which case a tag may store or store and execute the program(s). A run command may alternatively specify programs stored on a tag. The reader may instruct a tag to execute the program(s) upon receipt, upon a trigger event, serially or in parallel, and/or may cause the tag to modify the program(s) by adjusting parameters. The reader may instruct tags to execute the program(s) via the run command or another command, which may be sent prior to tag singulation. A reader may cause a tag to determine whether to participate in a subsequent inventory round, modify a behavior during a subsequent inventory round, or store a result in a tag memory, based on the executed program(s).

主权项

1. A method for a Radio Frequency Identification (RFID) reader, comprising: transmitting a run command to a plurality of RFID tags prior to transmitting a singulating command to a tag in the plurality of tags, the run command including a program comprising multiple instructions; causing the tag to execute the program in response to a trigger event; and causing the tag to, based on a result of the executed program, at least one of: determine whether to participate in a subsequent inventory round; modify a behavior during a subsequent inventory round; and store the result in a tag memory.
