I had an Idea to try to make card-io accessible. This is a library used in many apps to give an option to scan your credit card instead of entering in the numbers manually.
The issue is you still need to enter the 3 digit CCV number at the back of the card. So its does not save you much time.
How do people normally enter credit card details in apps? Memorise the digits and enter them manually? Copy and paste from somewhere? Is it normally a pain point? Would scan your card be useful?
The idea was to read out instructions to help you line up the rectangle so that the card scans. (e.g. 'Move left', 'Move down', 'Zoom in', ...) I tried it using a blindfold and someone telling me the instructions manaully and it took about 20-30 seconds to do it.
