Wise Cards and Access Control - A Look in the Not Too Far away Future

Highly popular in USA and Europe, smart cards are responsible for a strong impact in America.

At first requiring contact with the reader as a way to copy information, manufacturers have begun building proximity, non-contact type cards that transfer bi-directional data utilizing RFID technology.

 

By encoding the proximity cards and your readers with 64-bit encrypted "keys", manufacturers are able to provide highly secure credentials for gain access to and simultaneously open up a complete new world of possible applications for area cards.

Your data chips on smart cards can be segregated into separate program areas. Some manufactures provide as many as 16-different application areas. Each software area can be provided with a unique 64-bit "key" so that only specific readers can gain access to the information in that area.

In other words, you can have a reader in the catalogue that has the 64-bit key to application area # 4 in which the credit card stores all of your library information including which books you have examined out and never returned. A reader in the cafe has the 64-bit key to application area # 6 which debits money from your account for food purchases. The target audience on trainees housing building has the 64-bit key to application area # 1 where your area card access level information is stored which grants or loans you access into the dormitory.

With the advancements in smart card technology, manufacturers are working on standalone readers and lock-sets that are essentially "off-line" nevertheless they will be able to integrate with L. C. based electronic gain access to control systems.

The separate "smart" locks will integrate smart card readers with the ability to write down their transaction again to the smart cards. A person could visit hundreds of the "off-line" readers and when this individual reads his card at an "on-line" reader, the stored transactions would be downloaded to the repository. If a person is fired, or taken away of the database for any reason, the "on-line" system can write down their necessary information eliminating the, to each greeting card that it reads. In this way, the information is used in the "off-line" readers telling them to delete the access rights of the card.

In theory, this will allow large users of access control systems to customize their solutions and offer a mixture of on-line and off the internet readers that can be centrally managed while taking good thing about their existing communication infrastructure.

Another popular feature of smart cards is the ability to store bio-metric access control web templates which allows faster response from bio-metric authentication viewers. This ground breaking approach to bio-metric technology allows you to carry around your bio-metric template with you, rather than having it stored using the pc or the reader itself.
