Square Everywhere

It appears that Square is now up and running with mobile apps for iPhone and Android. If you aren\'t familiar with the business concept, take a moment to watch this video or this commercial to decipher that it\'s a way to take credit card via mobile app and a nifty headphone jack plugin that reads the card number.

While I doubt this is all that appealing to the vast majority of people I can see it being a huge boon to smaller artier types like poster creators or anyone in a band. They could certainly benefit from the compactness and convenience of it all.
