Why not one arduino plus one reader. Tap first card, send data to PC. Tap second card, send data to PC.

Hi Shannon,

I am a part of the Test Automation Team where we execute multiple test cases throughout the day without any manual intervention.

In order to test the scenario where there are multiple users we need two arduinos connected to the machine and each one will play its part i.e. A "Maker" with less rights can create a request and a "Checker" will check and authorize it. All this should happen without any manual intervention.
To be precise not manually inserting the card in the card reader and then validating it arduino would automatically input the pin for us.
