After more than 20 years of development, the access control system has surpassed the simple doorway and key management in the past and developed into a complete access management system. Through the computer system, when and where to release certain people, when to refuse certain people, when to send out alarm signals and to save the entry and exit records, the access control system can achieve the purpose of security prevention and timely alarm linkage, and it is safe in the work environment. It plays a major role in improving the efficiency of corporate management.
Development of access control systems
Combined with the development of access control technology and the security of access control systems, the access control industry has experienced several important development stages, including low-frequency card technology and high-frequency card technology, as well as the latest virtual credential card technology.
Low frequency card technology access control system
In the past 15 or 20 years, low frequency cards have been the standard in the security industry, providing efficient and effective access control. This card structure is simple, and anyone who uses these cards can enter the building. Anyone holding a card issued by the company can enter the building; this person can be an employee who owns the card issued by the company or a perpetrator who uses the stolen or lost card to pass the door. In order to increase the security of low-frequency cards, companies add visual security information such as photos to their cards. Employees wear ID/access cards with their own photos, and security personnel are trained to check who does not have the corresponding authentication information. To provide basic authentication methods. These low frequency cards, often referred to as proximity cards or ID cards, are now easily replicated. Since the criminals can make copies of the low-frequency card through some equipment, they can freely enter and exit the building. Unless there is a surveillance camera in the building or someone witnesses the person entering the building, it is impossible to know that unauthorized personnel have passed the access control, thus giving the access control system Security brings instability.
In the view of security managers, distributors, integrators and equipment manufacturers (OEMs), HID's 125 kHz RFID Prox card and card reader are the industry standard for access control systems at this stage. The HID proximity card is reliable, affordable and seamlessly integrated with the access control system.
Today, HID Prox technology still offers great price/performance and convenience. However, the 125 kHz RFID card technology and card format are not as secure as contactless smart cards, which has led to the development of access control systems to contactless smart card technology.
Non-contact high frequency smart card technology access control system
At present, the networked access control system for non-contact high-frequency smart card technology is widely used in various sectors of society such as government departments, financial institutions, transportation, energy, intelligent communities, factories, hospitals and other fields. By embedding multiple layers of security components in the smart card chip, all the doors are managed by the computer, powerful access control functions and permissions are set, the door is in and out in real time, and the entry and exit records of all the doors are queried. The more doors, the more the settings are. Easy and easy to manage.
At the same time, the access control system can communicate with the computer, and the access control software installed on the computer can be used to set the permissions of the card and query the entry and exit records. Without using the computer, the system can also run normally offline. The software can run the permission and parameter settings, and can monitor the entry and exit of each door in real time, and make statistical attendance reports. Easy to set up, easy to manage, and more secure.
HID Global iCLASS? Contactless card technology has become the industry standard for high-frequency technology smart cards. In 2002, HID Global introduced the first generation of iCLASS technology, extending the advantages of proximity cards to a more powerful and versatile platform, which is equally reliable, convenient and cost-effective. At the same time, the platform can be encrypted and verified by data. Provides greater security.
To make the access control system more powerful, HID iCLASS 13.56 MHz contactless smart card technology and read/write fields are interoperable and support a variety of applications, such as biometric authentication, microelectronic payment, and PC secure login. The iCLASS technology platform has been providing reliable service for nearly 10 years, and together with the multi-technology multiCLASS solutions used by HID Global, has become the standard for efficient, secure and efficient access control systems.
