Good news! our company has developed leading-edge products.
You do not need marked cards and lens, you also do not need a complex analyzer! BUT! You can become a champion! as it exists? you just send us your IPHONE or SAMSUNG, and we establish our new program on your phone that can scan the image maps (normal maps without Crappie) from the front of a camera phone and called the suit and card numbers through headphones. once you know well who has any cards in his hands, of course easy to win the game!
