Whether you’re running a small business, gearing up for your summertime lemonade stand, or simply want a way to process the door charges at your next multi-kegger, Square can help. This new service uses a small headphone port-connecting card reader and accompanying iPhone app to allow you to accept credit, debit, and pre-paid gift card payments anywhere you have an Internet connection. The customer signs with their finger, and can even have the receipt sent directly to their e-mail account. Beats the hell out of the ol’ metal cash box.
