Personal QR code generator - "Baby what's your phone number"

So the next new bar trick may be a bar code...ok that worked about as well as every other line I've tried in my life. Anyway, for the uninitiated QR codes have been around for a while but not too many folks had access to a one stop shop to generate QR's. Kaywa has filled the gap with a super easy to use site that allows you to select your content type (url, sms, text or phone number) and generate a image link.
For the un-initiated this image can in, theory, replace a business card (also you can cut down the awkward time it takes to put a number in your phone in a dark nightclub) and quickly connect you to a user who has a QR reader in their smart phone, you do have a QR reader in you smart phone don't you? Come on, all the kids are doing it. Seriously, take a minute to find a reader program you like and add it your phone you'll find that a number of companies have already begun adopting the tech.
