Hey Ho,

i have tested your libary and it works nice. Thanks you for this!

But i have a problem that the method _checkParity() will failed on all NFC/RFID Sensors that i put at the sensor.
Is there any known issue about this?

I have add some debug output if it fails.
Here i have 3 NFC Chips that gives me every time the same binary output.

parity check failed

Do you have any idea?
thanks a lot

Hi, i tried this library and it is great. Good job. Everything works but for the first time scanning my rfid tag, it does not detect. Then if i try second tag, it will be detected and working without any issue from now on. This only happen once each time the app started, so i have to scan one dummy tag to get it working.

I'm not familiar with weigand protocol and I think i missed something. Do you have any idea which part should i check? Thank you.

Hello,

Do you think we can port this to Node-RED ?

Thanks! :)
