Access card is our common smart card, Access control system equipment, is the current maintenance of community security protection door. But with the continuous development of technology, many community Access cards can be brushed, such as Access cards in Fuzhou can brush more than one community? Who is responsible for this, let our experts to analyze it.

Residents of a community in Fuzhou can open the gates not only of the community they live in, but also of other nearby communities. It turns out that the Access card the residents said they were using was purchased at the community business office a few kilometers away, and because the Access card could open not only their own community gates, but also those of the community they purchased it from, the residents were concerned that their community

Fuzhou City, an Access card can be swiped through multiple neighborhoods? Who exactly its responsibility?

Security.

Community resident Mr. Li said that after the installation of Access control, the community has no security guards on duty. If any Access card is free to enter and exit, it means the whole community is in a semi-vacuum, which is very unsafe. therefore, residents said that if the Access control system is so insecure, it is better to revert to ordinary locks, which are safer to open with a key.

For access control card can brush more than one community, experts said: should be caused by the laziness of the issuing company

Fuzhou Lock Association technical experts, said Master Yu, each Access control currently has a set of 16 different digital numbers in the ID card. However, if the Access control system fails, as long as the magnetic card signal is encountered, it can be opened. After testing, the reporter ruled out this possibility.

Master Yu also said that in practice, many card issuing companies will be lazy. For example, a community with 1,000 owners, each household issued 3 cards, you need to enter in the host 3000 times. Many card issuing companies are too much trouble and may only enter 100 numbers, then use 100 numbers to make 100 Access cards and the remaining 2900 copies. Some card issuing companies make Access control systems for multiple communities at the same time. they even enter the same 100 numbers in each community and then duplicate as many Access cards as possible. This way, one card can open the doors of multiple communities."

Master Yu said there are two ways to solve this problem: one is to renumber the Access card and update the data in the host, the other is to replace the entire Access control IC card system IC Access card system IC Access card with stronger confidentiality, IC Access card is currently the most secure Access card, not easy to copy, high security.
