Abstract: An exemplary electronic apparatus monitors whether a security badge remains within an area proximate to the electronic apparatus in order to protect against loss or theft of the badge especially when the user is away from the secure environment for which the badge facilitates access. A transmitter periodically transmits a poll signal intended for reception by an RFID module attached to the badge, the poll signal having a predetermined magnitude to limit the effective reception range of the poll signal to the proximate area. A receiver can receive a reply signal generated by the RFID module in response to receipt of the poll signal where the reply signal includes identification information that is unique to the electronic device. The received identification information is compared with first identification information stored in memory of the electronic apparatus to determine if the received identification information matches the first identification information.

Abstract: An exemplary vehicular apparatus includes a radio frequency receiver adapted for receipt of signals transmitted from intelligent street sins. A computer receives recovered digital data from the receiver, where the digital data represents information contained in the signals received by the receiver. The computer parses the digital data into separate fields and identifies a first field containing a first value that represents a predetermined type of vehicle for which the information contained in the other fields is relevant. The computer compares the first value with a stored value in memory to determine if the information contained in the other fields is relevant to the vehicle and recovers the information contained in the other fields if it is determined that the other fields are relevant to the vehicle.
