Square continues to add functionality to its mobile payment platform, and the latest addition is its new Register app for iPad. The refresh brings a sleeker interface and greater Card Case integration along with analytics to break down sales by transaction type and chronology to track your business' performance. Additionally, you can set up custom permissions to limit employee access, create customer loyalty programs and there's an improved inventory system feature as well. Naturally, it still relies on Square's trusty card reader for swiping cards and charges 2.75 percent per transaction using Visa, MasterCard, Discover or American Express. Small businessmen, your payment chariot awaits, so check out a video of the new Square Register in action after the break.
