Pay different

Using cellphones to ease offline purchases is a crowded corner of tech investment. Most companies are tackling one aspect of purchasing, like mobile payments or coupons. But Mr. Dorsey is thinking big. He wants Square to be involved in every step of the transaction process by replacing cash registers, loyalty cards and paper receipts. “We think it should be one system,” he said.

The start-up faces formidable competition. Square’s goal is to replace cash registers and point-of-sale terminals and the companies that make them, like Verifone. Square is also taking on the many start-ups that offer cellphone loyalty cards, like Foursquare, and competing with Google, Apple, PayPal and major credit card companies and banks to provide mobile payments.
