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

By encoding the playing cards and 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 distance cards.

The information chips on smart cards can be segregated into separate app areas. Some manufactures provide as many as 16-different application areas. Each software area can be provided with its 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 collection that has the 64-bit key to application area # 4 where credit card stores all of your library information including which books you have inspected out but not 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 closeness card access level information is stored which scholarships you access into the dormitory.

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

The showering "smart" locks will combine smart card readers with the ability to write down their transaction back 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 data source. If a person is fired, or taken away of the database for any reason, the "on-line" system can write down their necessary information getting rid of the, to each greeting card that it reads. In this way, the information is utilized 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 supply 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 layouts which allows faster response from bio-metric authentication visitors. This progressive 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.
