Case for USB RFid reader

thingiverse

This is a case for a USB RFid reader module called "134.2Khz RFID ISO11784/85 FDX-B EMID MINI Module" that I found here: https://www.aliexpress.com/item/134-2Khz-RFID-ISO11784-85-FDX-B-EMID-MINI-Module/32717871216.html The module comes with the antenna simply taped to the PCB. This case moves the antenna away from the PCB (which should be an advantage) and of course makes it the entire assembly a bit more sturdy. Printing and assembly should be straight forward. The lid can be secured by a small countersunk screw. It may be a good idea to add a small piece of some soft foam material to support the antenna. The module itself consist of a NUC122LD2 Arm.based microprocessor from Nuvoton. Little is said about how to use it, but it seems it acts as a USB keyboard device, and upon detecting an RFid device, it will extinguish the LED for a brief moment and emit keycodes corresponding to the ID detected, followed by return key.
