We all know that poker games are always full of mystery for we cannot know the poker results until it turned. However, as a professional marked crads contact lenses center, we can help you to uncover the mystery of poker by using our marked playing cards cheating devices.
We have two kinds of marked playing cards, one is back marked cards, which the invisible markings are printed on card backs, another is edge marked cards, the luminous ink marks are printed along card edges. Both of them can keep unfading at least for 2 years! By wearing our infrared contact lenses or IR sunglasses you can see the back marked cards clearly, while barcode marked cards can be read by our poker analyzer system.
