[From Stephen Trew] Square ditches $1,000 per week limits, has 800,000 merchants processing $2 billion per year. "Square - an app and iPad/iPhone accessory is growing quickly. It turns your iPhone or iPad into a point of sales device so you can take payment from credit cards etc. Small scale retailers and businesses will see this as a big opportunity to save money. And one more thing, Square is from the creators of Twitter."
