Uses for Kinect

I do think there can be actual uses for kinect. For instance having a picture associated with a credit card in order to use it would be kind of cool, this black friday i had at least two run in's with people trying to commit credit card fraud. I think it's application in the hospital would be pretty cool too, my mom is always bothered by things going on to patients, so to be able to see and react to a patient from home would be very convenient. She used to work with the criminally insane and drug addicts too so using that for rehabilitation may be a possibility...or it might let those criminally insane express their insanity...regardless I think the application of the kinect has great potential in the work force and should be used
