Square

There are a lot of apps destined to fizzle and die in the market, but one that I think will continue to gain ground is the Square Register. It can take an iPad and make it a portable cash register (provided there is wi-fi nearby) that will record and submit any transactions. One of the biggest small-scale problems today is that nobody carries cash, so how am I supposed to pay two dollars to that cute little girl selling lemonade? Square Register comes with a free card reader - no more than a few square inches in size - that can allow the user to swipe credit cards and charge the money right to their account. Despite the obvious credit card percentage takeaway, this presents a simple solution to those that can't pay because of a lack of cash. Cab drivers, salvation army reps, burrito trucks, and all sorts of small/medium scale businesses could leverage this app to great effect.
