I have the RFID reader working with a ESP (wireless) and the VHS Membership cards.
Currently the prototype on my desk, checks the cards against Nomos (members management system) to see if the members card is valid and what permissions they have, then flips a GPIO pin accordingly. First project is to do the inside door, then asset control (laser cutter, lathe, etc…)
There will always be a non-card way to enter the space, access the tools, etc… Having the card access control will not prevent people who do not have a membership card from using the tools.
I was waiting until the Nomos Hackathon before installing it.
I also have a game set up that uses ANY RFID card (including the VHS membership cards, or compass cards) that you can play while at VHS.
