The answer to this depends on the type and brand of invisible ink you use. There are three types: heat-activated inks, chemically-activated inks, and light activated inks. Heat-activated dyes change color upon heating. This can be achieved by heating up the paper using a heater, ironing or even a hairdryer. You can also use common household items like laundry detergent and soap. Even toy invisible ink pen pens work this way.
A special pair of glasses can also make invisible ink visible. In fact, many people wear these spectacles while playing poker so they can see the invisible ink-marked cards. These glasses look like regular sunglass and are usually printed with UV ink. These glasses can read the invisible markings found on the backside.
These invisible ink glasses are often sold in a package with a set of marked cards. These glasses have a similar appearance to a pair sunglasses. No one will know the difference. These invisible ink glasses can help you read the invisible markings on the back of a marked deck of cards in a variety of environments, including day and night, white and black lights, indoors and outdoors.
