Causing RFID tags to backscatter more codes
First Claim
1. An operational processing block for a Radio Frequency Identification (RFID) reader to communicate with an RFID tag storing a first code and a second code, and able to backscatter the first code responsive to receiving a first command, comprising:
- a component for;
causing a third command to be transmitted to the first tag; and
receiving, responsive to causing to be transmitted the third command, backscattered from the first tag a combination made from at least portions of the first code and the second code without causing to be transmitted any commands while the combination is being backscattered.

Abstract
RFID reader systems, readers, components, software and methods for causing RFID tags to backscatter a combination made from at least portions of a first code and a second code stored in tag memory, without transmitting any commands in the interim. In a number of embodiments, therefore, a separate command does not have to be sent for also reading the second code, thereby saving time in inventorying the tags. Plus, the combination can enable reading tag codes during tag manufacturing that are not otherwise readily available to read in the field.
