I'm amazed that this idea actually caught on in the first place. "Wait, you mean I can put every single source of (non-cash) money in a single card, for a single point of failure? And if it breaks, I'm effectively penniless? WHERE THE FUCK DO I SIGN UP?!"

Also imagine it gets stolen, good luck remembering all the cards you had in there and banks you need to call. Payment gateway route, like paypal, gives same convenience and less headaches.
