Using my cell phone to reserve a hotel room is now standard practice. Why coundn’t I also get the key to my room on the cell phone the same way I get the boarding pass for my flight on it? Well my question, I found out just now, is being answered by the Holiday Inns Chain that has announced a trial that began early September in Houston and Chicago.

It is just another little step in increasing the ways we can use our cell phone. And, of course, what I am really looking forward is to have an app on my phone tracking all what I am doing with it, so that I can use that information as reminder or to get better services.
