Square CEO Jack Dorsey is on stage at TechCrunch Disrupt right now, and he just announced a new product from the company called Square Register. It's an app for the iPad that prety much turns the device into a full on cash register on steroids. It also includes a bunch of analytics, which lets users see all sorts of data. For example, a coffeehouse can see how many lattes they sold last Tuesday, how many customers also bought biscotti, or what trends happen when it's rainy out. The product works with a consumer app called the Square Card Case which acts as a digital loyalty card, menu, receipt holder, map, and payment card all in one. The new Register and Case Card service is debuting with 50 merchants spread across San Francisco, Los Angeles, New York City, St. Louis, and Washington, D.C. These include bakeries, coffee shops, restaurants, salons, flower shops, and more.
