Can you make your own hotel management system and use your smart card to open the smart locks of other companies? Why? What should I do if I can?

1, the lock factory generally does not provide refreshable data packets, only gives a certain amount of fixed data, and cannot refresh itself;

If you can pay, you can get the software. If you can crack it, you can refresh it yourself.

3. The guest room system and the door lock software are separated, and there is no docking function. The door lock only has the reading function, and the management software cannot change the password system at will;

4. Manufacturers will definitely consider the problem of scattered passwords among different customers, and generally there will be no similar passwords in the same area. So if you want to crack it from an initial stage, you still have to learn a lot. I hope you don't use it for illegal purposes.
