Apparatuses and methods using command sets specific for controlling the operation of a type of the RFID transponder to which the command sets are transmitted
First Claim
1. An apparatus comprising:
- a first circuit configured to communicate radio frequency signals with a plurality of different types of radio frequency identification (RFID) transponders having an integrated circuit that carries out commands; and
a second circuit configured and arranged to;
communicate with the plurality of different types of RFID transponders via the first circuit,detect the type of each of the plurality of different types of RFID transponders based on communications with each RFID transponder via the first circuit,control the operation of each of the plurality of different types of RFID transponders by transmitting commands to the RFID transponders, using command sets specific for controlling the operation of the type of the RFID transponder to which the commands are transmitted,store the command sets and configuration flag data in a lookup table that lists features supported by each of the different types of RFID transponders,in response to receipt of configuration flag data from an RFID transponder, identify the RFID transponder as a configuration RFID transponder having configuration data for at least one new command that is different than commands in said command sets, access the configuration data from the configuration RFID transponder, and use the configuration data for the new command to generate a modified command set by modifying an existing command set to include the at least one new command while maintaining existing commands within the command set, to enable control of a new type of RFID transponder using a communication protocol, andin response to detecting an RFID transponder of the new type, control the operation of the integrated circuit in the RFID transponder of the new type using the modified command set, by sending a command from the modified command set to the RFID transponder and using the command to control the RFID transponder to operate the integrated circuit in accordance with the modified command set.

Abstract
Certain exemplary aspects of the present disclosure are directed toward an apparatus in which a first circuit communicates with a plurality of different types of RFID transponders using radio frequency signals. A second circuit detects and communicates with the plurality of different types of RFID transponders via the first circuit, respectively using a command set for the type of RFID transponder that the first circuit is communicating with. The second circuit, in response to detecting an RFID transponder having configuration data for a new command set, accesses and uses the configuration data for the new command set to update a configuration of the second circuit to enable communication with the new type of RFID transponder.
