Multiple USB Mag Readers
Is it possible to connect 8 USB Magnetic Keyboard Wedge card readers to an Arduino Uno or Mega?

Re: Multiple USB Mag Readers
You wouldn't use the USB version - you would use the PS/2 version of the mag readers.

You can't connect 8 to either a Uno or a Mega, because they don't have 8 interrupt pins. The best you can do is a Mega, which has six external interrupts.
