The elevator card system cannot be cracked.

At present, there are more and more elevator credit card and access control brand systems in the market, and more and more access control and elevator credit card systems are installed in the property. However, with the continuous upgrading of technology, M 1 card has been cracked more and more like the ID card system in previous years.

Cracking the M 1 card is very simple. A complete set of 122U equipment and distribution software can copy one card. There are many things on a treasure, and the technology is very simple. Learning needs 10 minutes.

Many businesses provide anti-copy technology. The commonly used card is M 1 for full encryption, but the full encryption has been completely cracked by PM3, so the full encryption system can no longer prevent copying. Then the merchant introduced the rolling code encryption system. The principle of this system is very simple, that is, when swiping a card, the hardware device sends a random verification code. Even if an identical card is copied, it can be prevented from being copied if the random code is different from the copied card after swiping the card first. I thought this was a once and for all solution. But underestimated the ability of cracking technology. Many businesses use rolling code encryption, which is basically not copy-proof. The hype completely blinded the shortcomings of this technology.

In fact, the biggest driving force for copying and cracking is profit. If a community card can be copied and cracked, basically about 30% people will choose to copy it. Needless to say, it is profit-driven or doing something illegal. Many people think that copying is copying cards. Now the trend is to choose brands with high market share and crack software. Many brands have upgraded themselves to the seventh and eighth generation, but they will copy after half a year. There is a simple reason. If you crack a company's card issuing software, you can basically copy all the cards easily. No, you can easily issue cards to all the property communities in the country. This has a great impact.

Does cpu elevator swipe card to prevent copying?

The CPU card is copy-proof. However, the compatibility is very poor. If you use ladder control, access control and building intercom to swipe your card, it is not compatible.

After being cracked endlessly, many companies have no way to upgrade the M 1 card technology, so they have to wait for the introduction of financial-grade CPU cards. This is because they really have no good way to solve the problem of replication. I can only look forward to the anti-copy technology of CPU card. However, when M 1 card was introduced, it was also said that 1000 would not be cracked in a few years, but in just a few years, the technology of cracking cards has spread all over the world.

But this is not the biggest problem with CPU cards. The biggest problem is China's software design. A brand access control and ladder control system uses a set of public version software, which is the biggest problem of CPU card. Once the software is cracked, the CPU card will have the same fate as the M 1 card.

Ok, I'll announce the answer to the fate of the elevator credit card and access control being cracked. There is only one way, the whole system is networked.
