I am willing to bet that the number of shopaholics out there will increase if the Braille Credit Card ever gets created. This credit card was designed by by Kwon Ki Nam to help blind people make safe and secure purchases.
The Braille Credit Card is extremely intelligent and well-designed. The card reads off purchases after your card's been swiped and also allows you to sign for them using your thumbprint. I have a soft spot for designs that help make life easier for the blind, which is why I really want to see the Braille Credit Card come to reality sooner rather than later.
