Card access systems define who gets into the building and when

A card access system is a security system that uses a card, keyfob, badge or biometrics to grant access to a building, room, or area.

A card access system operates when a reader on the outside of a locked door, reads the card, keyfob, badge or biometric credential data and if that credential data is verified then access will be granted to the authorized user. 

Card access systems offer several advantages over the traditional lock and key systems.   The most important advantage is the control of access through the facility.  The second most important advantage is the audit trail or the ability to track activity.  Clearly, there is an increased level of security and convenience to the organization.    Other advantages are the cost savings from not having to re-key a building or program a card with an expiry date for a contract or short-term hire.   Another advantage is different users can have different access levels within the organization. 

Card access systems can be configured to work with a variety of different card types, including proximity cards, smart cards, magnetic stripe cards, and biometrics.

Yes, card access systems can be integrated with other security systems such as video surveillance, alarm systems, and intercom systems to provide a comprehensive security solution.

Lost or stolen cards can be easily deactivated in a card access system to prevent unauthorized access. Replacement cards can be issued to authorized users as needed.

The cost of a card access system varies depending on several factors, including the size of the system, the type of cards used, and the level of security required. A basic system can cost a few hundred dollars, while a more advanced system can cost thousands of dollars.

There is minimal maintenance for a card access system.   Yes there are standby batteries that drive the system in the event of a power failure.   Those batteries periodically need to be replaced.  Scheduled maintenance is the best way to ensure proper operation.

Yes, card access systems can be used in conjunction with traditional keys to provide an added layer of security. For example, a card access system may be used to control access to a building, while keys are used to secure individual offices or rooms within the building.
