Introduction
Poker is one of the most popular card games in the world, played in casinos, home games, and online platforms. While traditional poker relies on skill, strategy, and luck, some players use poker cards with invisible ink as a trick to gain an advantage. These special cards are designed with hidden markings that are only visible under specific light conditions, usually with the help of infrared (IR) or UV contact lenses.
In this article, we will explore what poker cards with invisible ink are, how they work, their different types, and ethical concerns surrounding their use.
