So I'm a complete Arduino newb. Though I have some experience with markup languages, electronics, electrics etc. I've been tasked by an old-mens club to provide qualification based (in four classes) access to machinery (drill presses, table saws, lathes (wood & metal), mills etc) by way of an NFC RFID tag/fob to switch a relay to supply mains to the machine. Let me know your email address so I can send you a bock diagram (.dia or .png).
I anticipate mains input to a 12vdc PS that powers a microcontroller (Arduino) that receives input from an RFID detector and then outputs 12v to a relay to then switch mains to the machine.
What I don't need are complications such as wifi et al. Thus I need to know which model of Arduino should I use for the purpose and whether anyone already has software to upload to the Arduino for said function.
Any Arduino can in principle read the output of an RFID reader, and if the tag info matches a stored value, turn on a relay.
The search phrase "Arduino RFID reader" will turn up countless tutorials and videos.
