42
What it does: 42, one of our top picks, measures and personalizes the in-store experience by allowing customers to scan the bar code of clothing items. This information is stored and the retailer can choose to send customers emails about when those items go on sale. Through Foursquare, 42 also shows companies where shoppers are from and what they're sharing about the store based on a special "consumer sentiment" algorithm. Who Designed It: Cathy Han, Nicholas Porter, Lucas Lemanowicz, and Sarah Hum. [Photo via]
