The concept of access control, according to security experts, refers to the ability to allow or deny the use of certain resources by individuals, or enter the area specified. In individuals who are not allowed to deny access to files or to the location specified, the control mechanism that is installed or placed to manage the physical resources. Examples would be the cinema, with tickets being the main access or entry pass, so they are not holding a ticket would be denied entry. It will also be used for electronic or digital systems, while the private text document on your computer or files can only be obtained or made read to certain users. Card access devices used primarily to gain entry to the area that has been in / out points set up electronics. Points of access control can be designed with gates, iron doors, gates, car park, ramps and other obstacles.
Most of today’s industry and business card access control using the various technologies used in identifying the ID or badge for access control systems. Experts say that electronic security and a common technology used for these cards are bar codes, smart cards and other digital security equipment. ID will be embedded with a number that will be read by a digital card reader. After this, the number and then sent to the main access control system or database, where the sensor center to make decisions based on the information shown on the eligibility of a person. If the information shown on a certain card is inserted into the main access control list, it will open up access points that have been identified and admit to the individual. The transaction is then entered into the system for storage and retrieval possible, and reports can be generated to list or disclose the identity of those who enter a particular access point at any given time.
A common control electronic access systems typically use a computer to help alleviate the limitations of mechanical standard keys or metal keys. In this type of mechanism, the entry of a person is limited depending on whether he / she pay the ticket, has received approval from his superiors, or has obtained the documents and other obligations. The main access points of the body can be constructed to allow entry only, or they can be made in such a way that they used for the eyes of both the entry and exit. Security guards, doormen, dams and other staff could be deployed to man the entrance of this, together with the setting up turnstiles and other physical devices. Fences can also be used to prevent the circumvention of access control systems, and it will be useful for these areas are very large. Some systems also uses personal identification number (PIN). A PIN will generally consist of 4-8 digits, and experts say that the benefits of using this system as one of access control mechanisms to memorize numbers, access numbers would not be lost or left behind somewhere. However, there are disadvantages to using this system. Some say that it can be a problem if you ever forget your PIN number of a particular, or any other events to see or find an authorized individual PIN. Others view the system less secure than PIN smart cards, bar codes or magnetic stripe cards.
Currently, there are several control access cards, ID badges, and manufacturer of security software, to produce a variety of badges that uses standard bar code, magnetic stripe, contact less smart cards and other related design can also be used self-service without cash, online payments and use of OEM products. They are also able to provide consulting services, and assist in the establishment of access control points, and system design services and installation of secure data storage system for all records.
