The latest startup from Jack Dorsey, cofounder of Twitter, is a hit.
Square is a device that plugs into a smartphone and lets users accept credit card payments.
Microbusinesses love the thing, NPR reports, and Square is now processing millions of dollars every week.
The Square dongle seems to be a winner, even if it’s not as elegant as some other mobile payment solutions. Venmo, also based in New York, lets users exchange money just by linking a credit card to the app.
