FF cards with barcode?
 

Delta has a bar-code on the revers of the FF card to access the PNR and other functions at kiosks.
what other programs do use this system? are you aware of other programs having a bar-code on the FF card? what is it good for?

thanks for your help!

if you have a photo/scan of such a card, thanks for sending me a link, I need this for a presentation at work. Thanks for your help ^ please pm me for details.
