In case you haven't been paying attention, Square, the company that allows vendors to accept payments from various mobile devices, is starting to become a big deal. Now reporting days with over $11 million in transactions, the kids in San Francisco are looking to solve the pains of small business owners while driving repeat usage with a new opt-in customer loyalty system. Coming in the form of a software update, version 2.2 will empower merchants to track repeat visitors and offer sweet incentives to their regulars. For consumers, you'll be capable of seeing these discounts from within the Card Case app, along with letting your awesome presence be known to the shopkeeper -- so, don't be surprised when some owners come grovelin' at your feet. Not to become too futuristic, Square is also going old school with new features such as wireless control of cash drawers and receipt printing. After all, it's hard to look to the future without knowing from where you came.
