Mobile wallet app lets you pay by saying your name at checkout

The mobile payment startup Square has announced two apps for smart phones and tablets that work in conjunction to let you pay by simply giving a store clerk your name.

The apps, one for consumers, Card Case, and one for store owners, Register, take the place of a cash register, and are free on both Apple and Android-based devices. Consumers see a list of businesses in the vicinity that also use the Square payment system. Square also has a key-sized credit-card reader that plugs into your phone's audio jack, pictured to the right.

With the Square app, you store a chosen credit card, much like you would with PayPal.

You can only pay this way if you and your phone are both present.
