A Card Access Systems is an electronic door locking method that allows you to manage entry/exit to your business or office facility. Electronic magnets are installed either onto the top of the door frame (mag lock), or inside the door frame, utilizing your mechanical door lock devices, called "door strikes". A programmed card is presented to a "reader" that decodes the information in the card and either allows or denies entry. No more hassling with keys! Keyless entry to buildings, garages, kiosks, storage buildings, and more!
