• OK, this is pretty cool. Jack Dorsey, one of the guys behind Twit­ter, has another startup which promises to rev­o­lu­tion­ize the process of credit/debit trans­ac­tions. It’s a tiny square. It requires an audio jack. That’s it. Like Twit­ter, it’s dead sim­ple. Unlike Twit­ter, it’s not a super-esoteric con­cept at the out­set, beg­ging peo­ple to fig­ure out why it’s nec­es­sary. It just makes sense. Kudos. Could some­one give us a rea­son to use this? source
