NFC Card Case - Full back

This is a card case for NFC cards that are 3.375" x 2.125" (85.725mm x 53.975mm).

While this has been designed for my own use of the NFC cards, it will also work for the very popular TapTo project for the MiSTer FPGA (https://github.com/TapToCommunity/tapto).

There is a slight slope at the back of the case to allow cards to rest in a nice visual position.
