I'm using TagMo on my phone to write some 215 nfc tags. Ordered a bunch of coin collector cases, transparent inkjet printer paper, and clear acryllic spacers to layer art within the 3mm x 30mm of space within the case.

The fun part comes next... Making the Photoshop templates and cutting out countless circles of paper...
