Access Control - Multi Use Function That is Useful in Many Businesses By Nikki Stephens
Access control is the ability to allow or deny entry to a specified area or a particular function of the organization. When the card holder is denied to enter a location or to access a resource, a control mechanism is used to allow or deny access to a resource or a physical area. Access control is used for access to an entire system or can be placed on a small item such as a text document. Some access control systems use access control cards. This card allows entry or denies entry into a secure area that has electronic entry and exit point such as a gate or door.
Businesses that utilize access control cards use a wide variety of methods to identify the holder of the ID. Bar codes, smart cards, proximity cards and mag stripes are some of the technologies implemented. The ID card has a number embedded on it by a method such as the ones listed. The number is read by a digital card reader as the card holder approaches the secured area. The number is read and sent to the computer hosing the main access control system. The sensor in the system matches the transmitted information to the database and allows or denies access based on the credentials submitted. If the information submitted is located on the main access control list, the system will unlock the identified access point and allow entry. The transaction is logged into the system for retrieval as required by management. A report may be generated to identify the access provided by the system for a specific timeframe.
Most electronic access systems utilize computers to provide increased security over the standard lock and key system. Entry to an area may depend on payment for a ticket, authorization from management, or other criteria. The controlled area may limit access to the area or may include exit privileges as well. Depending on organizational requirements and the size of the group to be managed, various additional security measures may be needed. Security guards, doormen, turn styles, fences and other security products may be used to increase the security level to the proper levels for the event or group.
Some systems use the personal identification number (PIN) technology. Although it does provide a control to accessing systems, the PIN system is often discarded as the access number is easy to forget or pass on to other unintentionally.
A number of manufacturers currently produce ID cards, access control systems and security control systems. The systems provide secure access to vending, physical access, online payments and access to product usages. The manufacturers and their distributors provide consultations and recommendations for setting up the most efficient access control points for specific situations. The system design and installation are also handled by many distributors for their clients. For more information visit website
