Differences Between Barcode and Infrared Marked Cards

When it comes to gaining an edge in competitive poker, marked cards have evolved into two highly advanced forms: barcode marked cards and infrared marked cards. Though both are designed for discreet gameplay advantages, the technology behind them—and how they’re used—differs significantly.

Barcode marked cards feature invisible machine-readable codes printed along the edges of each card. These cards are designed to be read by external devices, such as hidden cameras connected to poker analyzers. Once scanned, the analyzer instantly calculates outcomes and sends real-time data—like the winning hand—directly to the player via a wireless earpiece. This method offers extremely high accuracy and is ideal for automated analysis.

In contrast, infrared marked cards are printed with special ink that is only visible through infrared contact lenses or sunglasses. The markings—often suits and values—are embedded on the card back and read manually during play. This method relies on the player’s ability to interpret the markings visually, offering more control but requiring experience and precision.

While barcode systems offer speed and automation, they require more setup: a scanner, a compatible analyzer, and reliable communication. Infrared marked cards are simpler to use, requiring only the right lenses. However, they demand sharper focus and careful handling to avoid detection.

In short, barcode marked cards provide data-driven support with external devices, while infrared cards offer a more hands-on yet subtle approach. For players who want to master both techniques, understanding their differences is key to making the right investment.
