Kyle Lechtenberg of Auburn University created these Visual Assistance Cards. Basically, the special cards go on top of touch screen PIN devices at retailers who don't have Braille keypads. This allow users to input their PIN while keeping their information private. This helps give blind people more independence.
Imagine deprived with your sight and making a store purchase. Everything is in your basket ready to be swiped for its total amount. However, a debit card is all that you have. How will you enter your PIN? Will the clerk have to do it? This innovation solves that problem.
