Playing cards can easily be marked during the course of any card game. This approach offer some advantage and some disadvantages. One advantage is that there is no need to bring a marked deck to the game. In fact the scam can be worked at a moment's notice without any prior planning. The deck would preferably be brought in by one of the suckers.infrared contact lenses
The disadvantage is that the owner of the deck (be it a casino or a host of a home poker game) may discover the work at some later time. For obvious reasons a smart cheat should not consider putting any permanent work on the cards, if a two-handed game is played. However, if several people were involved in the game and there is little chanced any of them would meet again in the future a card cheat would probably not care too much about some suckers catching a wind of it once the money is already in the bank. In any short scam the main objective is to take the money and go. If the work is discovered no one will know for certain who put it there. Common sense would suggest it should probably have been the guy that took all the money, but if the deck was used before and/or after the game in question it becomes hard to reconstruct when the cards could have been marked, or by whom.
Marking cards during a game is a common practice. Sometimes there is even more than one person marking cards at the same time. One card hustler that I am acquainted with once shared a good anecdote with me. He had been marking cards during one particular poker game and had discovered someone else's work on some of the cards, as he was putting on his own work. He figured out who the other cheat was and also figured out his code. He then proceeded by replicating the other guy's work on some of the other cards and completely threw him off balance. The other guy eventually figured out he'd been had, but had very little moral stranding to file any kind of complaint or clam for a refund.luminosu contact lenses
