it has a purpose!

When I was at the San Jose airport on Friday to check in for my flight home, I arrived at a Continental kiosk and got out my e-ticket and prepared to enter the ticket number, when an attendant came by and said that if I had my “id”, I could swipe it and it would bring up the trip. I was skeptical that a Louisiana driver’s license would do anything at an airline kiosk in California, having never swiped it for anything ever. I tried it, and it immediately brought up the information. I was shocked.
