Previously, you swiped credit card on card reader and then signed your signature. But now, you can pay with your credit card quickly and simply by using credit card and signing signature all at once. By swiping the card with the corner of the credit card (magnetic), the card information will be read. We can save time and confirm the payment amount well. From now on, waiting in the line to make a payment and going through several steps will disappear. We only need to sign our signature to make payment. It will be convenient for both us and clerks.
