A concept from Yongsuk Kim, the Braille Credit Card empowers a visually challenged person to know the amount of money that has been charged on their card. The card is able to generate the amount in Braille which makes it easier for the user to know the sum that is needed to pay. The card also has an inbuilt miniature speaker which reads aloud the figures for further assistance.
This special card could also be useful for old aged people who suffer from poor eyesight. It wouldn’t be possible for them to understand Braille but the integrated speaker could lend a helping hand.
