I agreed. Paying with card is fraught with slow terminals, bad card readers, many prompts in a row (Credit or debt, is this the right amount, do you want to donate $1 to something, do you want it all on one card, would you like to sign up for a store credit card, do you want cash back, how much, do you want a receipt?). For some reason, these all have a 2-5 second delay between them. I could make a system on a $2 arduino that was faster.

Some places like Starbucks seem to get it right. Swipe card and go.

Target however likes to hit you with all the options. Self checkout is even worse.
