Credit cards can now be used for access control without an actual billing transaction taking place. Businesses can now have employees use their personal credit cards to gain access to secure parking and electric vehicle charging instead of issuing a separate PIN or ID Badge.

Liberty Access Technologies (LAT), a Liberty PlugIns, Inc. subsidiary, announced today that it had been granted a patent by the US Patent Office that describes a process where credit card numbers can be used for identification and access control purposes without an actual billing transaction being initiated. This concept has wide application in access control environments such as parking and electric vehicle (EV) charging systems.

“Business parking operations have to provide service to a mix of customers; visitors, employees, vendors and company owned vehicles.” says Chris Outwater, President of LAT. “Having to issue separate access control devices to each class of user increases complexity and cost. Our system takes advantage of the fact that most people already have a unique ID badge…their credit card.”

Parking structures and EV charging stations that accept credit cards for payment by public users will have tenants and employees register their personal credit card numbers. When they swipe their credit card the system will recognize that user and grant access without any billing transaction taking place. Public users will use their credit cards to pay for parking or EV charging in the usual manner. Liberty will make this feature available in their Hydra R access, data and energy management control system for EV service equipment (EVSE) later this summer.
