Secret RFID Iphone box

Here is a video of it working: https://streamable.com/2jgh7 Make your own secret stash hidden as nothing more than an empty iPhone box. Lock the box by sticking either of the two RFID tags over the reader, which is located in the bottom left corner of the box. Unlock it by putting a specific pattern of RFID tags, in my case, the blue RFID tag, wait two seconds, then the white RFID tag, wait two seconds, and finally the blue RFID tag again. This can be changed to any two of your own RFID tags in the code or just one instead of two. I originally made this to be used in an escape room I created for my friends, and it worked flawlessly - taking them a while to figure out. Feel free to use it for whatever you like. There are two models included: one for aligning the locking frame, and the actual locking frame itself.
