Square first launched their service a year ago, since then they’ve grown into a valuable credit card processing resource for individuals and small businesses. Invented by Jack Dorsey after a friend lost a $2,000 art sale due to a cash-only operation. Dorsey (@jack) is also the guy who invented Twitter.
Unlike every other credit card solution, Square charges no upfront costs and skims a mere 2.75% off transactions. Unlike PayPal, which is also inexpensive, Square requires no setup on the part of the customer.
Available now for Apple iOS and Google Android, the Square app is free. It works in conjunction with a free credit card reader that plugs into the plain old headphone slot. The best experience comes from using the iPad app. Users can enter individual prices or use set up items in advance. Sales tax and tips can also be collected.
