I know this might be premature but I’m calling it now, Square will be the best thing to happen to the Smart Phones in 2010. Here is my reasoning:

Smart Phones have become ubiquitous all around the world. New phones and competing devices are popping up everywhere and new reports are being written on unreleased devices. These mobile devices have multiple uses to them; for example, the iPhone plays music, records video, emails, plays movies, twitters, facebooks….. oh yea it makes calls. Companies and innovators are trying to brainstorm the best idea for these smart phones and the best idea for 2010 has finally come to us. The company is called Square.

Square is not only trying to revolutionize the mobile device market but they are also revolutionizing Credit Card purchases. It’s not just a simple beautiful app and it’s not just a small easy to use attachment, it’s the whole package! Visual Math: New Application + New Attachment + “Web 2.0″ company = very large growth potential for the smart phones and mobile devices, alike.

Square is the brainchild of Jim McKelvey, and backed by Jack Doresy (co-founded of Twitter) and Khosla Ventures. Square is a small credit card reading device that plugs into your headphone jack. To make a purchase, the vendor will type in the amount and slide the card. The vendor then hands their mobile device to the customer who checks the total and signs their signature with their finger. Once that is complete, the vendor enters the email address of the customer and emails the receipt to the customer… and that’s it!

Rumor has it that Square will give the device away with purchase of the app and monthly subscription of services with no commission. This will benefit small business very much by creating a static price for easy expending!

Let me know what you think about this Square idea.
