Secondary card reader
First Claim
1. A secondary reader of a Radio Frequency Identification (RFID) tag, the secondary reader comprising:
- a secondary receiver including an antenna and a receiver circuit adapted to receive an RFID signal from the RFID tag, the RFID signal being in response to a primary reader signal from a primary reader, the receiver circuit adapted to receive information regarding an attempted reading of the RFID tag by the primary reader;
an indicator coupled to the secondary receiver and adapted to indicate receipt of the RFID signal by the secondary receiver; and
control logic coupled to the secondary receiver and adapted to indicate receipt of the RFID signal by the secondary receiver;
wherein the secondary reader is adapted to communicate, via a communication link, alert signals to a plurality of uncoupled devices, the alert signals including information regarding the primary 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.
