> (1) How is this more convenient than using my card or cash? I don't buy the argument that carrying a wallet is an inconvenience. A card takes virtually no space. Even if it's not an inconvenience to you that doesn't mean it's not an inconvenience to anyone else. I for one dislike carrying my wallet and have opted to get a phone case that can hold my cards (cc, and drivers license). I'd imagine if I was in a big city and could pay with my phone I wouldn't need those cards either.
