We waited anxiously for the markings to appear. But nothing was immediately discernible on the cards. I rapidly got the feeling of being had, but then suddenly a very pale bluish-greenish tinge appeared and took from on the cards. It looked like a small fingerprint. We started down at the cards in disbelief, as if observing a butterfly somehow turning back into a caterpillar.
We kept the lenses in our eyes and wanted for the solution to disappear. After just a few minutes it became fainter; 20 minutes later it was completely gone.
I was shocked. The ramifications of such a device were insane.
I gave a final rub over the cards with my index finger to make sure there were no remnants of the solutions sensitive to touch. If there had been, the scam would have proved useless. But they remained as smooth as the rest of the unmarked cards in the deck. Fundamentally, the contact lenses and the solution were sound they only problems to deal with were those of transporting the solution to the poker tables and its application to the cards.
