Hello All,

I am currently trying to build a MakerSpace and have all of the expensive machinery require RFID to turn them on so I can limit them to certain people. I am not sure on how RFID works but I am wanting it so that each time someone new is able to use the machine, I only need to assign them a new card and not add them to each machine individually.

so for example, someone might be able to use Machine A, Machine B and not Machine C while using one card. I also want to be able to have it so that if they get the training I can simply just alter their card so they could use Machine C as well.

Then, if this is possible, is it possible to record who has used each machine?

thanks
Mitchell

Hello,

I am currently trying to write the code for this program and don't know how to start. I just want the RFID to wait and read a card and if it has the correct code, it turns on the relay until the card is removed and waits 30 seconds until it turns off.

I don't want to use a database, I want to so that the RFID reader looks for a certain code and once it sees that, it turns on. This way I can program the RFID card to contain that code and turns on that machine. Then I want to make it so that each machine has a different code so that one card will be able to be programmed so that it can turn on any number of the machines as I like without turn on others.

Thanks
Mitchell

You can't do that. Their is no way you can take code from an RFID card's sectors and run it. That is not permitted by the architecture of the processor.
