SYSTEM AND METHOD FOR DETECTING PRESENCE OF ONE OR MORE USER IDENTIFICATION DEVICE |
摘要 |
A method for detecting presence of one or more security token comprises a host device transmitting a wake-up message for receipt by the security token. Based on the wake-up message and a condition of the one or more security token, the security token either awakens or returns to an inactive state. The wake-up message comprises a security code that is unique to a host device and an instruction code that is configured to selectively instruct at least one of the one or more security tokens associated with the vehicle to awaken. A system for detecting presence of a user includes a host device configured for transmitting a wake-up message to be received by a security token. The wake-up message comprises a unique security code and an instruction code that is configured to instruct security tokens associated with the vehicle to awaken.
