Hi how many reader we can connect to single arduino without losing its function ( delay , slow read, etc )

For simple 125khz rfid

Hi @wiryonolau , I have only tested with two. If you have more readers, you can try out and let us know your result.

Hi @wiryonolau , I've tried with 6 Mifare wiegand card readers and it works fine and is extremely fast.
Thanks @jpliew for this library!

Ok, I'm testing with 3 and no problem in detecting but we have difficulty in differentiate which reader is tapped. Is it possible to know using this library ?
