Hacking Scratch Lottery Tickets
Design failure means you can pick winning tickets before scratching the coatings off. Most interesting is that there’s statistical evidence that this sort of attack has been occurring in the wild: not necessarily this particular attack, but some way to separate winners from losers without voiding the tickets.
Since this article was published in Wired, another technique of hacking scratch lottery tickets has surfaced: store clerks capitalizing on losing streaks. If you assume any given package of lottery tickets has a similar number of winners, wait until you sell most of the way through the packet without seeing those winners and then buy the rest.

Why bother? the easiest way is to shine strong UV light on the scratchable area and in many such tickets you can figure out the text underneath. I had one case personally where a store gave you such discount cards when you stood in queue in front of the cash register. There was a big mercury vapor lamp above the queue which was like a turkish bath but the up side-you could see through and know the size of the discount. It was too small so i just asked for another card and the discount was much more significant.
Sometimes low-tech is the best approach…
