How to read invisible ink?

Invisible ink markings on playing cards have been used for cheating in gambling and card games for decades. However, with the advancement of technology, it has become more challenging to detect these markings without the use of specialized tools such as invisible ink glasses.

Invisible ink glasses are special glasses that are designed to detect hidden markings on playing cards that are invisible to the naked eye. These glasses use advanced technology to filter out specific wavelengths of light, allowing users to see invisible ink markings clearly.

To use invisible ink glasses, simply put them on and look at the marked playing cards. The invisible markings will appear visible to the wearer of the glasses, allowing them to determine the value of the card or its position in the deck. This is a popular technique used by professional gamblers to gain an unfair advantage over their opponents.
