Designed for poker enthusiasts and magicians, this article covers everything from technology to practical tips. Ready to elevate your game? Let’s explore the world of marked playing cards.
What Are Infrared and Barcode Marked Cards?
Infrared marked cards feature invisible markings, typically applied with invisible ink, that reveal a card’s suit and value when viewed through specialized contact lenses or glasses. These markings are undetectable without the right equipment, making them ideal for discreet use.
Barcode marked cards have unique barcodes printed on their edges, readable by a poker analyzer or scanning device. These devices relay card information in real-time, often via an earpiece or phone, perfect for team-based strategies or high-stakes games.
Both types are available in trusted brands like Bicycle and Copag, known for durability and quality.

How Do These Marked Cards Work?
Infrared Technology: Infrared markings are created using luminous or infrared ink, which absorbs specific light wavelengths. When viewed through infrared contact lenses or invisible ink glasses, these markings become visible, showing the card’s rank and suit. The ink is invisible under normal lighting, ensuring secrecy.
Barcode Technology: Barcodes are printed on the card edges using specialized ink. A poker analyzer or poker camera scans these barcodes during gameplay, decoding them to display card details on a connected device. This setup is often used in professional settings for its accuracy and speed.
Both systems require specific tools: infrared lenses or invisible ink glasses for the former and a scanner for the latter. For a deeper dive, explore our guide on Infrared Marked Cards and Barcode Marked Cards A Comprehensive Comparison.
