Speaking at LeWeb today, Jack Dorsey talked more about Square, his new mobile payments startup.

The company plans to launch an API that will allow Square to connect to other financial systems and book keeping software. That’s helpful and in my mind, absolutely necessary to get small businesses using the sytem. The bigger news?

Dorsey and Square want the payment dongle to be available for free.

How, exactly, they will make that work remains to be seen. Since it uses an audio jack, it’s possible that we’ll see Square running on other platforms besides the iPhone, though that will likely require changes to the hardware to connect to, say, a BlackBerry.

The Square team is working on the private beta while beefing up system security, which will need to be a major focus of the company if they’re going to interconnect with a variety of financials systems.

I, for one, am interested to try this out. I have members of my extended family that could use Square to enhance their businesses.
