GigaOM has a nice write-up of PayDragon, a nice app that allows you to order and pay for your food (or other item, I’m assuming) with a single tap. Well, maybe not really a single tap, but you get what the market-speak means. The main difference between PayDragon and Square’s Card Case is that PayDragon can read QR Codes…which is a plus, I guess?
