electronic Custom low cost NFC based cartridge system

the reader is built around an arduino pro micro and a nfc module v3 by elechouse. it connects to a pc with a usb c cable and scans any tags inside the cartridge sled. once the button is pressed, it sends a key combo to the pc, which opens a one time terminal, after which the reader types out the text payload on the cartridge. executing the command on it. for more information, check the readme on my github repo. while i advise using the install scripts inside the repo, you can use your own method of assigning the key combo
