I kinda like it... It's helpful for when I make a purchase online and I need to enter the code of my Visa/Mastercard, since my telephone is on the desk next to me and my wallet usually in my jacket, it could be handy. You could also scan some other cards containing something like a tax number or other information you might sometimes need. Might benefit from an add on feature to scan business cards?? You'd have to offer a search function though, I think?
