NFC TAG VENDING MACHINE

A big vending machine use to create and write new NFC Tags. It can do up to four at once, took me 5 hours of straight hair pulling and finally works, it vaugely tells you how it works by itself, but if you cant figure it out ill gladly help you out in the comments. You can do whatever you want to it, and even reupload it if you want, just please credit me.... otherwise ill cry (ps, i was really tired when making this so it might not work well or not be well optimized in the form of exploits.) im so tired....
