The markings on the back of Mahjong or Domino are a little bit difficult for people to read, in spite of wearing the infrared contact lenses. Due to this reason, we have developed a better marked poker reading device. This marked cards reader device is leather belt spy camera. The leather belt poker scanning camera is extensively used in different places nowadays. That high quality leather belt spy camera can be used for reading the markings of marked cards which cannot be seen by our naked eyes. After this leather belt scans the barcode of marked cards, it will transmit the poker signal to poker analyzer and then the poker game result will be shown on the monitor. Finally, you can get the poker winner result in advance.
