The next big thing from Twitter founder, Square

In February 2009, Jim McKelvey wasn’t able to sell a piece of his glass art because he couldn’t accept a credit card as payment. Even though a majority of payments has moved to plastic cards, accepting payments from cards is still difficult, requiring long applications, expensive hardware, and an overly complex experience. Square was born a few days later right next to the old San Francisco US Mint.
Today the Square team is focused on bringing immediacy, transparency, and approachability to the world of payments: an inherently social interaction each of us participates in daily. We’re starting with a limited beta and rolling out to everyone in early 2010. More information
