user19065: I bought a PN532 from Elechouse (documentation here) because I need to read IDs from Type B NFC cards.
My problem is that even if they say the hardware supports Type B, the official libraries an examples they provide are not made to.
I have not problem reading Type A cards, but nothing happends when I tap Type B cards.
After long searchs on internet I found that absolutely every PN532 sellers have chosen to support only Type A cards in their libraries because according to them, a librari supporting both types would have taken too much space in Arduino's memory.
So today my problem is as simple as that: how to read Type B NFC cards using PN532 on an Arduino UNO?
I'm a bit new in Arduino so after many hours of searching and trying I couldn't figure out how to do it.

user14464: I dont have an exact reply but
1) are you certain the other tags are type b?
2) hace you tried connecting the reader using a UART USB cable? You could use libnfc, to check if the reader works.
And going forward at commands FOR the reader are a good way to debbug.
