I want the c++ code used in swipping machine. Help me with this

What is this "swipping machine"? I used Google to see if it would shed some light and it was unclear.

If I change the words to "swiping machine" I get some hits about Point Of Sale but even then we would never code the credit card reader entirely today.

Why? Today's point of sale don't use the mag stripe by default. Instead the card reader is tasked with using the security chip or a payment system such as Apple pay and others.

This means if you want to develop a point of sale you would source the card reader/payment system and use their API for the payment system. You would never write the code for the "swipping machine."
