Invisible Ink Marked Cards

We should always prepare a plan B, because you never know what would happen. Even in a poker gambling.  If you think you must win with the luminous marked cards and infrared contact lenses, that's wrong. How do you know others didn't have the marked cards? So, maybe you should prepare the barcode marked cards , scanning camera, analyzer system, exchanging cards devices and the remote control dice at the same time. Prepare plan B and C so that you still can have everything in control. 

No matter in life or at work, self-confidence is very important. Do not lose your confidence because of the comment others say to you. Whether they judge you on purpose or not, just keep away from these people. And you also shouldn't doubt yourself in a gambling. When you using the exchanging cards devices , invisible marked cards,  remote scanning camera ,or a winner analyzer system, you should believe that others won't notice what you do at first. Second, you should practice and practice, so that you can use these devices flexibly.
