Korean USB credit card
 
America tries to act like the leader in technology sometimes, but it’s really slow on the uptake. You know those cool credit cards that are starting to pop up more and more, the kind that you can wave in front of the gas pump instead of actually having to go through the usual “insert card and remove quickly” routine? Those may be all the rage in America (or not: I don’t know many people who actually have one), but they’re old news. All the cool kids (who live in Korea) have USB credit cards now. They don’t have to enter information to make purchases online; all they have to do is plug their credit card into their USB port to pay for stuff online. Take that, third-world country America!
