In this rapidly changing world of information technology and potential threats, if users still rely on outdated access control system technology, they may face the risk of intellectual property theft, data leakage, and violations.
Nowadays, the current situation of domestic access control systems is not optimistic, because many users still use outdated access control systems that contain insecure traditional credential card technology, such as using the MF card serial number as identification, but reading the MF serial number or The sector method has been cracked, including common smartphones that can clone MF cards, videos of cloned MF cards can be easily found online, or tools to copy cards can be bought.
Therefore, the use of outdated access control systems and the use of credentials without encryption authentication are self-evident. Does your access control system need to be upgraded? How to upgrade?
Let's first understand the working principle of the access control system and the innovation road of credential card technology.
Working principle of access control system
A general access control system usually consists of a card, access control card reader, an electric lock, and a controller.
The card reader is used to obtain the card number information of the person who swipes the card, convert it into an electric signal, and send it to the access control controller. The controller compares the received card number with the card number permission stored in the controller to determine whether the person who swipes the card can be at this time Segments enter and exit and complete actions such as unlocking and keeping locked according to the judgment result.
The networked access controller can be connected to the management computer through the RS485 bus or TCP/IP network, receive personnel and card number authority information sent from the computer, and can also send event records to the management computer
Credential card technology, the road to innovation
The era of physical contact with magnetic stripe cards
In the 1960s, the magnetic stripe card was born. As the original card-swiping technology replaces manual locks and keys but requires manual swiping to transmit unencrypted credential information to the card reader, which has poor security, inefficiency, and wear and tear.
The era of non-contact high-frequency cards
Around 2000, contactless smart cards appeared, providing more sophisticated technology than Prox. These smart cards use high-frequency technology (13.56MHz), and through the implantation of multi-layer security components in the chip, they can be networked with computers for rights management.
The era of smart devices
With the evolution of the times, the access control system is developing in the direction of virtualization and mobility. Now the platform can achieve security authentication through the virtual credential card installed on the smartphone. This method uses NFC or Bluetooth as the communication method, provides additional diversified keys, has verification and encryption functions, and fully reflects its safety and security. Advantages in portability.
Back to the current global outbreak of the epidemic, Shanghai, Beijing, Shenzhen and other international metropolises need to focus on preventing and controlling the occurrence of imported epidemics. Especially for places with high-security requirements such as banks, credential swiping is still a safer choice than face recognition. As long as the front-end card reader is replaced or upgraded to an HID Bluetooth card reader, the dual choice of mobile phone or card can be realized. Use your mobile phone to swipe your card to enter and exit, and you can read data from 3 meters away, which is safe and convenient.
