Inventor Paul D'Souza's Tiffy's Template is designed to prevent the visually challenged from getting cheated
“Close your eyes," says Paul D’Souza, handing me a small card-sized strip of plastic with step-like incisions at one end, a notch on the side and raised dots across it (it says Tiffy’s Template and offers instructions in Braille). The Bengaluru-based inventor hands me a currency note (my eyes are still closed) and asks me to wrap it around the strip. The note covers the notch and reaches the top of the second step of the device, “That is a 100 rupee note," he confirms.
