This week when I was at the DIY at the Museum of Vancouver I was thrilled to see some craft tables with product set up for sale. The only problem was I didn't have any cash and there wasn't an ATM around. It made me think of a demo I had seen back at Christmas time on WilloToons on something called Square. It's an iPhone app and a cool way to process credit cards on the iPhone. As Willo says on her original post about it, it comes in super handy at craft and sales events. So I just thought I'd put this tech tip out there in case some of you weren't aware of it yet. Visit Willo's blog to read more here and here to visit the Square site.
