What is a card reader door lock?

A card reader door lock is an electronic access control system typically fitted to doors of office buildings, apartment blocks, and other restricted areas. It works by scanning a pre-programmed access keycard when the user places it close to the reader. If the card is authorised, then access is granted automatically, and the door unlocks so that access may be gained.

This method of allowing entry is becoming increasingly popular as an alternative to traditional conventional electronic locks because it provides more secure access control than mechanical locks and can be programmed with limitations on certain privileges according to user requirements.

While they may require a higher initial investment than conventional locks, card reader door locks provide continuing cost savings due to their low maintenance requirements and easy scalability based on changing security needs.
