Card Cheating Mobile Phone
Elie Bursztein, head of the anti-abuse research team at Google made an interesting discovery. He revealed this modified smart phone at the recent DEF CON 24 Conference.
He purchased a specially modified smart phone which uses infra-red light to identify face down playing cards. It resembles a standard Samsung mobile phone. However, this card cheating mobile phone works by using three secret led lights which can read the topside of a specially marked deck of cards. It works by identifying the surface pattern of each card. It only works with a modified deck of cards but it has opened up some hi-tech cheating possibilities.
