Customer Has To Swipe Their Credit Card On A Box Connected To The Computer Via USB?

2. This is the main thing that we need. We saw this implemented at a Staples.What we want is for the computer to be locked, and to unlock it, a customer has to swipe their credit card on a box connected to the computer via USB. Once the customer does this, they can use the computer, and a small timer in the corner shows how much time has been used, since they are being charged per minute. Then, once the customer is finished, the computer will relock and print a receipt.oes anyone have an idea on how to do this? We've tried programs such as Smartlaunch, but we were having trouble with it, and it appears that an account has to be created for each user. The point of the set up we require is so that we don't have to be present for the customer to pay to use the computer.
