Abstract

Currently, proximity badges require the user to have close proximity in order to restrict access, which usually requires the user to bring the badge to the reader using a hand. RFID readers can be designed to operate at a higher transmit power level, thus increasing range, however this may cause unwanted false triggers from tags not intended to trigger the reader (such as a person walking near the entrance but not intending to enter). A better solution would be a hands free operation to allow the user to enter a badge access area, while maintaining security by preventing inadvertant authentication by people passing with badges.

Badge Access Method for Hands Free Entry

Using close proximity badge access is secure with respect to inadvertent authentications, however this can be cumbersome and impractical if someone is carrying an item with both hands. Using a foot activated pedal or other method of indicating the desire to enter causes a temporary boost in the gain of the radio transmitter authenticating with the near by badge, enabling access if the badge is in extended proximity. The same request mechanism can also trigger automated opening of the door to provide hands free access for someone carrying items with both arms or someone who is handicapped and can not use their arms.

     A foot pedal is used by the person wishing to gain access to extend the operational range of the badge reader for a short period of time. This allows the person wishing to gain entry the ability to have the badge on themselves, and not have to hold
it in close proximity. This also maintains security and avoids inadvertent "swipes" when the pedal is not in use, as the range will shrink back to a close distance after a short period (if the pedal remains depressed) or the pedal is released. This method allows for access without having to use ones hands, in the case they are carrying something heavy in both arms or they are handicapped in such a way that they can not use their hands/arms.

     "Foot pedal" in this case may be an actual pedal, a mat that detects user presence based on weight, or other mechanism.
