Is the wall picture just a normal wall painting? Of course the answer is “no”. For a professional poker manufacturer, wall paintings are a good choice to insert a mini camera lens for marked cards inside. This anti-poker cheating device can scan the luminous ink barcode marked playing cards in poker games or in magic show. We can hang these wall pictures in the room wall, and then turn on the remote control and poker camera will work for you. Your poker partners can see the invisible marking of suit and number on the backside of poker cards. If the scanning angle is incorrect, you can adjust it to a best angle by remote control. When you use this anti-poker cheat device, remember to take our barcode marked playing decks.
