When was the last time you hit target , and do they transactions actually hit for over 500Mines by far is Target. Those guys in there are sweet as candy. There system lets you swipe effortlessly. But if your swiping for high amount lets say 500 and above make sure you plastics match the last four cuz the system will tell the cashier to input the last four. Radio Shack is good, Office Depot has good computers you can card but b careful they have a fingerprint reader in stores when you swipe. Hope that helps a lil
