Small-business owners have big decisions to make when it comes to how they accept payment -- and investors should be taking note. Along with the traditional setups associated with Visa (NYSE:V) and MasterCard, customers can also pay using their iPhones or Android devices.

Mobile payments are expected to reach the $600 billion mark by sometime next year. Players include Google Wallet, eBay's (NASDAQ:EBAY) PayPal Here, and Intuit's (NASDAQ:INTU) GoPayment. But one company drawing a lot of attention is San Francisco-based Square, which will roll out at your local Starbucks (NASDAQ:SBUX) soon. In the video below, Motley Fool analyst Rex Moore speaks with a local business owner who's sold on Square because of its innovation and low cost.
