In the tripod turnstile access control system, identification technologies such as biometrics, card recognition, and password recognition, as the "core" of the entire access control system, have always been the focus of the security industry.
Among various recognition technologies, card recognition technology is popular in the market due to its stable performance and convenient use. At present, non-contact smart cards appearing on the market include identification cards (ID cards for short), Mifare1 cards, IC cards, and so on.
It is understood that ID cards such as tripod turnstile access cards and parking cards used in the community are called inductive "magnetic cards". When leaving the factory, the manufacturer determines a unique number for it; in the process of use, the card reader of the tripod gate access control system performs safety certification by reading the serial number in the card. This type of card has low cost and simple operation. It is very popular in the market by real estate development companies and property management companies, and has a high market share. At present, 80% of the communities in my country adopt ID smart access control cards.
Although the cost is low and easy to use, its drawbacks are also obvious. In addition to the serial number determined by the manufacturer, the ID smart card has no other confidentiality measures, and the serial number itself is public and readable. Ordinary people can quickly obtain the number and copy it using a card reader.
