Topic: Modding the ACR122

Since the ACR122 doesn't work well with the PC/SC layer in the middle, I am really thinking of scrapping the MCU (on my version it's a chip-on-board) and use the UART from the PN532 directly, which I think may make the reader much better.

I have a Bluetooth serial module (3.3/5v) which can be hooked up to the reader.

Has anyone done similar things before?
