Square has so far focused on helping businesses take payments; now, it's ready to make payments to get those businesses off the ground. The company has launched Square Capital, a quick financing service that uses card transactions for repayment. Every time someone makes a purchase, a small cut of that sale (on top of the usual card fee) goes toward covering the advance. Square is purposefully keeping things as simple as that. There's no application process, and there's no due date -- if business gets slow, it just takes a bit longer to pay things off.
