Twitter founder set to start new company

Jack Dorsey sent out a tweet letting his followers know that he was, “Getting ready to embark on something new and entirely different. Excited!” The new company has been codenamed "Squirrel". From what I've scraped off the grid what I learnt so far is it's a service that allows anyone with an iPhone to become a seller. A bit like wireless credit card swipers you can see in most restaurents and shops on Grafton Street and anywhere else in Ireland, you can carry around your iPhone and take payments. From what I can gather so far it seems like a Mobile version of PayPal.  Squirrel will be a physical device that attaches easily to the smart device as well as an application you download from an app store.
