Man creates device for visually impaired people to distinguish fake currency

In 2013, Paul’s visually impaired friend, Tiffany, requested him to create a device that enabled blind people in India to distinguish fake and real currency. It was this request that prompted the creation of the TIFFY template, named after Tiffany.

For the visually impaired in India, it is easy to be tricked into being given different change or wrong notes, seeing as almost all Indian currency notes are the same width, making them extremely hard to differentiate. Each note is supposed to have a marking that represents its denomination, but these markings tend to fade very easily, making the blind and visually impaired a vulnerable target to scam. However, after Tiffany’s request, Paul, who had been developing products for the visually impaired for a number of years, set out to change this.

"As the welfare of the visually impaired is very close to my heart, I dedicated my time to make this device," says Paul.

The device is a small, sleek product that initially was made out of metal but is now made out of the same material used for credit cards, and only takes 45 seconds to use.

A crowd funding platform called Fuel a Dream discovered this product and is trying to make it accessible to the visually impaired across India, enabling the device to be free upon request.
