Abstract
A security system and method is provided. An embodiment includes a security access device that includes a first transmitter for transmitting authentication to a computer and a second transmitter for transmitting verification information to a computer. The first transmitter is typically active and consumes power from the access device, while the second transmitter is typically passive, and consumes less or nil power from the access device. When the security access device is initially brought proximal to the computer and activated, the authentication information is sent to the computer and the user is logged in. Periodically, the computer will query the passive transmitter for verification information, to ensure that the security access device is still proximal to the computer.
