Embodiment Construction

[0050] first reference figure 1 , illustrates an example access control system 100 in accordance with at least some embodiments of the present invention. Access control system 100 may include reader 104 and RFID device 108 . RFID device 108 may be a passive device that does not require power supplied from an internal power source. The power required to operate a passive tag is provided to the tag by electromagnetic energy sent from the reader 104 . The electromagnetic energy may be generated at antenna 112 of reader 104 and received at antenna 116 of RFID device 108 . According to at least some embodiments of the present invention, antenna 116 (or the entire antenna circuit) may not be allowed to respond to electromagnetic energy generated by reader 104 if RFID device 108 is not moved in a predefined motion or a predefined sequence of motions. .

[0051] Accordingly, the passive RFID device 108 is operable when the passive RFID device 108 has received electromagnetic waves...

Abstract

The present invention is directed toward an RFID device that includes a motion sensing mechanism. The motion sensing mechanism is adapted to sense motion of the RFID device and then selectively allow or restrict the RFID device's ability to transmit messages, which may include sensitive data, when the RFID device is placed in an RF field. Thus, the motion sensing mechanism is utilized to control access to data on the RFID device to only instances when the holder of the RFID device moves the RFID device in a predefined sequence of motion(s).

Description

technical field [0001] The present invention is directed generally to the detection of card movement, and the utilization of said detection information and its control operation. Background technique [0002] Radio Frequency Identification (RFID) systems use RFID readers to wirelessly detect the presence of nearby RFID tags and read the identification codes stored in the tags. The identification code in the RFID tag can be used to control access to protected resources by allowing access only when an RFID tag with an authorized identification code is detected. Typically, authorized RFID tags are issued to authorized users to ensure that only authorized users can access protected resources. However, if an authorized RFID tag is lost or stolen, an unauthorized user can present the authorized RFID tag to gain access to the protected resource. [0003] Currently available installed RFID systems use a variety of different complex encoding and signaling methods, some of which are...
