- RFID”
) tag comprising;
reading an RFID signal at a primary reader, the RFID signal being from the RFID tag and being in response to a primary reader signal from the primary reader;
reading an RFID signal at a secondary reader, the RFID signal being from the RFID tag and being in response to the primary reader signal;
sending information obtained from reading the RFID signal at the primary reader through a primary reader communication link to a device coupled to a network; and
at the device coupled to the network, comparing the information obtained from reading the RFID signal at the primary reader to information obtained from reading the RFID signal at the secondary reader.

Abstract
A secondary reader and associated system are disclosed. In some embodiments, a secondary reader obtains and communicates information about a reading of an RFID tag by a primary reader by receiving an RFID signal that is responsive to a signal from the primary reader. In some embodiments, the secondary reader also receives an interrogation signal from the primary reader. In some embodiments, the secondary reader receives information related to the primary reader that may, in some instances, include a security key used to determine whether or not the primary reader is authorized to read the RFID tag. Variations on these and other embodiments are described more fully herein.
