Square Cash

Walter S. Mossberg:

The people helping me test were generally wowed. One called it “slick.” Another replied: “Done. Two secs.” A third, with whom I had trouble using PayPal last year, said she’d use it “1,000 percent.”

Square now lets you email cash to anyone free of charge. Sounds too good to be true, but judging from the quotes above, it’s really that magical. Keep an eye on Square – it seems that they will be playing a defining role in how we work with our money in the future.
