Data-on-card technology provides flexible security by using a credential to transmit system data between off-line devices and on-line management systems. Data-on-card technology provides an easy, cost-effective solution for managing access control. All-access data is stored on and distributed by the operating smartcard. When presenting a smartcard to an offline stand-alone door, not only does this control access rights to that door but, because of two-way communication, the door can also write data, like blacklist information or battery status, back to the smartcard. The smartcard then transmits this information back to the server via online wall readers that are able to update and receive information from the cards anytime and anywhere in the building.
Data-on-card systems can both read and write updated information at the lock/reader of both off-line devices and head-end systems and relay it back to the server. This is known as a virtual network. This two-way communication between the card and door allows the smart credentials to act as carriers, enabling the readers of each door to be updated with crucial information. Implementing this type of “virtual” network eliminates the need for having a wired or wireless lock at every opening. This significantly reduces the costs of the access control system.
Data on card systems are ideal for multi-family housing, apartments, and mixed-use facilities for updating credentials where there is a common entrance but with many locks throughout the buildings.
When an update is applied remotely, it is automatically updated on wired readers located at major access through-points such as entrances, elevators, and stairwells. When users use their card or fob at these wired readers, the updated information is downloaded from the reader. When a wireless reader is tapped, the update is uploaded to the reader. Information travels to and from wireless readers dynamically and effortlessly.
- Data-on-card technology provides comprehensive access control without the cost and complexity of wiring every door or the need for IT support/equipment.
- Online openings are limited to at least one central location.
- Eliminates the need to visit locks to make access updates.
