This is all true but not the problem you may think, you can go on line and get a generic magnetic card read for 10 dollars and not have to make any modifications. The second version of the scam also is true, it is possible to run peoples cards thru multiple times, even your code and or if you use a signature is available for the multiple times. But be careful who you give your credit card to, it will show up on the bill, so you can go back to the vendor. Problem, but not anymore than any other magnetic scanner has always had.
