I ran into a major issue with HT rejecting my try to buy high value cards. Then I asked a manager why they pulled all the cards the next time I returned to the store. Apparently HT was targeted by criminals posing as employee's of the GC company. They would call and pretend that they were testing the system. With the test they would ask the register person to scan a value in the card, then once in to give them the barcode number. They said the test worked fine and hung up. What the register worker didn't realize is that the criminals would fabricate the card with barcode and get the value off of it. I was told this, who knows if it is true but for full details I documented it here:
