he Credit Card for the Blind looks complicated but is quite simple to use. It uses the cardholder’s fingerprint (using fingerprint recognition software) as their signature and the Braille on the display for transaction details. An inbuilt speaker rattles-off the kind of products being paid for, thus giving the blind a complete account of the transaction autonomously. Giving them a completely secure and safe transaction. A really nice idea that for sure will be taken in consideration by Visa.
