Wall picture mini spy camera is not a normal wall painting. We insert a mini camera lens inside. So this anti-poker cheating device can scan the luminous ink barcode marked playing cards in poker games or in magic show. We can hang this wall picture poker cheating system in the room wall, then turn on the remote control. Your poker partners can see the invisible marking of suit and number on the backside of deck of 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.
