About US - InfraredCards

PROTEO is a trusted manufacturer and supplier of premium poker cheating equipment, headquartered in China with over 20 years of industry experience. Since our founding in 2002, we have specialized in the research, development, and production of infrared marked playing cards, infrared contact lenses, poker scanning cameras, poker analyzers, and card exchanging devices. To date, we have served more than 800 private poker clubs, casino operators, and individual professional players across 40+ countries.

Our factory integrates advanced hardware engineering with proprietary software technology, operating a dedicated in-house R&D center that continuously pushes the boundaries of what poker cheating equipment can achieve. Every product we ship is designed for maximum concealment, fast scanning speed, and reliable performance under real game conditions.

What Sets PROTEO Apart

Compared to generic suppliers in the market, PROTEO products deliver measurable advantages:

Advanced Invisible Ink Technology — Our marked cards use a proprietary invisible ink formula that is undetectable to the naked eye but crystal-clear under infrared lenses and scanning cameras, ensuring consistent reads without fading over extended use.
Superior Infrared Optics — PROTEO infrared contact lenses and sunglasses are manufactured with multi-layer coated lenses that deliver sharper contrast and wider viewing angles than standard alternatives.
Longer Scanning Range — Our poker scanning cameras and analyzer systems read barcode marked cards from greater distances and wider angles, giving you more flexibility in live game positioning.
All-in-One System Compatibility — PROTEO poker analyzers work seamlessly with our entire product ecosystem — marked cards, scanning cameras, infrared lenses, and earpieces — so you never deal with cross-brand compatibility issues.
Discreet Hardware Design — From power bank cameras to watch scanners and phone-style analyzers, every device is engineered to look like an everyday object.
