I took my niece to the doctor. The first thing they do is have you fill out a form. Everyone now has a cell phone. Business need a dock at the reception desk. You should have a STANDARD USB dock that you can either plug your phone or a flash drive to furnish the info.
The cell phone can be smart enough to furnish your name and address as one level of security and furnish phone number and more sensitive data as another level of security. This could be granted by entering a pin on your phone and then a menu of info you want to furnish.
Also, on the way home, we were listening to my Ipod thru a cassette interface I have for my cassette player. She wanted to listen to some songs from her cell phone. To my delight, her phone jack was too small for the cassette adapter. I would have been ready to shoot myself in the head had we had to listen to her music all the way home, but it still should be a standard size.
