TapTo NFC-Engine
Designed by BedroomNinja
Inspired by the PC Engine. This case is compatible with the ACR122U and another other small NFC readers such as the PN532. There is space on top to show off card art while they're inserted and a custom card template sized perfectly for it available in the TapTo Designer.
