It’s not square… it’s THE square! From the Square Web site:
Start accepting payment cards immediately with Square. No contracts, monthly fees, or hidden costs. Effortlessly manage all the money you take with an easy and intuitive interface.
Oh, and it’s good news for people who just want to use credit cards, too:
As a payer, get your receipts sent to your email or mobile phone instantly and access them securely online. You can also use a text message to authorize every payment in real-time.
Maybe one day we won’t have to deal with plastic cards at all – but until then, at least the process could be brought into the 21st century. Thanks to @Dom for the opportunity to share! Video demonstrations coming soon.
