I was changing the barcode reader I usually use.
with this one
Why the images are stretched?
The image taken from Google Images (to have a reliable reference) its supposed to be a square, and actually looks like a rectangle
Another question, sorry, I've got a lot of them.
Basically what I'm trying to find is an interface where if I connected a credit card chip reader via USB I can process the card. Does anyone know if Paypal, Square, Venmo, etc have an API that would allow me to charge the credit...
