Change & Charge Cash RegisterWill this be cash or credit? Your customer has picked out all their groceries, and now it's time to check out! Ring up each item on your cash register and give your customer their total. Are they paying with cash or a card? You can handle both! If they pay with cash, use your register to make exact change, and if they pay with a card, swipe it through your card reader. After you thank them for coming, you're ready to take the next customer in line!
