Smart card access control

RAM is partitioned by 32 1-K byte partitions and each partition is checked at a time. For a hotel, this could be the latest permissible checkout time, or for a secure facility, the system might limit access to certain days and shifts.

The access control system of claim 1, further comprising computer means, coupled to said acceptor means and separated therefrom, including means for retrieving the lock access information and the transaction information from said lock access information storing means.

Access Control

This is commonly called "anti-passback," and its purpose is to prevent more than one person from using a card to gain admittance to a secure facility. This approach is preferable to trying to centrally match a biometric scan to a database of profiles, which can be time consuming, or relying on a complete database of profiles stored in a reader located outside a secure area.

At the option of the system manager, each card acceptor can be programmed to hold the card numbers of cards reported lost, stolen or revoked. The access control system of claim 32, wherein said key means has a plurality of contact pads therein and coupled to the integrated circuit thereof for providing electrical contacts.

If you have a car park or private entrance, your smart card can even be used to access security barriers, giving you complete control over who enters your wider premises.

If CPU finds the installation data, then it examines the card type ID code of the data read from smart card If the provided real time is less than the check-in time and greater than the check-out time of a respective time duration, CPU sets the system to the "power-off" condition.

For example, an employer concerned about employee access to certain areas could issue smart cards as identification media and incorporate into the data structure an access code or series of access codes that will allow an employee to pass through certain doors, gates or other barriers but not others.

Once a customer card has been issued to a new customer and used to gain access to the room, no previous customer card will be able to activate the system.

Cards and Credentials for Access Control

There will be a separate access code for each level of security and sufficient data storage in the cards carried by hotel staff to incorporate multiple codes. The initialization includes, for example, setting the contents of RAM to predetermined values, providing control signals to enable RS driverand running interrupt routines.

Staff value the convenience of having a single smart card for multiple applications, making the cards less likely to be lost or misused, and more likely to be carried universally.

The RS driver provides interface between acceptor 20 and a portable or central computer which is optionally coupled thereto via a cable or some other medium. Then CPU examines the access code of the data read from the smart card and compares it with the access code prestored in RAM during set-up.

Smart Card Overview

How does a smart card system benefit facility managers. The access control system of claim 59, wherein said acceptor writes the transaction information into the integrated circuit card through a respective one of the contact pads during the time when the respective contact pad is electrically engaged with the acceptor.

An Intel microcontroller, for example, or equivalent, can be used. The access control system of claim 10, wherein the key access information includes a predetermined security code and each of said one or more lock access codes corresponds to the predetermined security code.

The access control system of claim 1, further comprising means for writing the transaction information into the lock access information storing means.

The method of claim 37, further comprising the step of storing said transaction information in the memory of the lock for retrieval at a later time. The access control system of claim 24, wherein said key means has a plurality of contact pads therein and coupled to the integrated circuit thereof for providing electrical contacts.

The clock and reset signals are provided for memory access control only for the serial memory type and because this type of card provides no internal clock signals. The access control system of claim 59, wherein said acceptor writes the transaction information into the integrated circuit card through a respective one of the contact pads during the time when the respective contact pad is electrically engaged with the acceptor.

The smart card is also adapted to record thereon transaction information provided from the lock to facilitate easy access of such information by the system manager. Smart Card in Access Control - Overview. A smartcard is a typical plastic chip card that contains an embedded computer chip which is either a memory or a microprocessor elonghornsales.com data that the chip is responsible for storing and transacting pertains to either value, information or a combination of both.

Smart cards can do a lot more for your business than simply let people in and out of your premises. Using cutting-edge technology, our cards can be used in a whole host of ways.

Access Control. Multi-Technology Readers Overview GE Transition Series multi-technology access readers feature simultaneous compatibility with multi-vendor credential. The benefits of smart cards don't stop there.

A smart card that is programmed to be read by different types of readers or by a multi-technology reader at different locations is expandable through the addition of new access control panels and readers.

Cyber Access Control – Card Readers for Enterprise Password Management. To expand a user’s Power LogOn network access control solutions to other computers, all that is typically needed is an additional card reader. SMART CARD TECHNOLOGIES WITHIN THE ACCESS-CONTROL 4 The use of smart card technology in control access offers many benefits to organizations that use it.

In authentication method such password-based method security risks are high. Password can. This is the end of the preview.
