Think this an interesting design and it’s commendable that designers put themselves in the shoes of the less fortunate. I am from a design magazine in Singapore and am writing about such design. Would be very interested in asking you a few questions! It’ll be great if you could email me back at melody_tan@pageonegroup.com. Looking forward to your reply asap. Thanks!

First, the concern that not every blind person knows Braille. This is very true, for that reason I also included standard numbers that were raised this helps those who don’t know braille determine which buttons to push.

Second the issue of people looking over your shoulder to know which buttons were pushed. This would be much harder than you think. The entire visual assistance card is white and in store environment the numbers are almost impossible to see the only reason you see them in the images is due to heavy photoshop work and using light at an extreme angle to accentuate shadows.

The third issue brought up incomparability with the software. This is the problem I will admit I don’t have a perfect solution for, but I have thought of how to alleviate it. The Visual Assistance Card is primarily designed to be cheap and would most likely be custom ordered by a corporation for their specific debit card machines. This would allow them to be designed around their screen size and software configuration. But you are right that it is not a universal fix. It goes on after the cashier assists the visually impaired person through all the steps and it is time to input their secure PIN number. It unfortunately does not allow a visually impaired person to navigate the process like a unimpaired person would but that is not the intent. It is designed as a cheap way for them to input their private information at a price point for the store that would be feasible and therefore is more likely to be implemented.

What the card doesn’t account for, is changes in the program on the pin pad.
An example is if they decide to ask for your “Club card”. There isn’t much of a way to get around doing that.
