This is a crazy story about custom hardware designed to allow for card game cheating, including not only poker but nearly any other card game. Custom hardware made to look like a cell phone plus IR marked cards equals total knowledge about what’s happening on the table.
Upon ordering the poker cheating device I kinda expected, based on the screenshots I had seen early on, to get a dedicated piece of hardware that kinda looked like a fake phone. However, to my surprise, the device, showcased in the picture above, far exceeded my expectations by being a fully functional phone with extra hardware dedicated to cheating. Also to my surprise, the device not only allows to cheat at Poker but to cheat at almost any kind of card games you can think of.
