Twitter Creator Has a Vision For the iPad (Photo)
Twitter creator Jack Dorsey (right) sets up his new product, the Square mobile payment system, on an iPad at Sightglass coffee in San Francisco. Dorsey is also an investor in Sightglass.
Availability on the iPad represented Square's official public launch (our initial review). Some people see big potential in iPad Point of Sale systems but others question the form factor and argue that mobile phones will make better mini-cash registers. Square has a product that works with iPhones as well.
