Jack Dorsey isn’t just co-founder of Twitter. He’s also the man behind an ambitious new startup called Square that is taking on the credit-card industry. Square — just launched in the US — lets anyone send or receive cash by inserting a one-inch-square plastic device into his or her iPhone or Android phone. You can take credit-card payments or send money to others via your phone — and you don’t need to deal with the conventional banks.
