SwIPe Software enables merchants to process card-present transactions utilizing a PC and USB card reader. This lightweight point-of-sale application was designed to work with Windows® based systems. The retail SwIPe software is installed on your PC. It runs in the background and communicates with the Tranzcrypt.com Payment Gateway. The software is only visible when you swipe a card, so you can run your other computer programs just like you did before and when you swipe a card, it automatically pulls up the swipe software screen.
