Tech: Fair and Square: Twitter co-founder Jack Dorsey simplifies buying stuff
- 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
