Our mashup Mobile Facebook ID card has been updated. It lets you create mobile identification card with your Facebook ID.
Mashup lets you create mobile web page with QR code that presents your name and photo from Facebook. This mobile web page could be simply bookmarked (saved) right on your mobile phone. You can present (show) this QR code (opened mobile page) on the some check-in point (gate etc). QR code could be scanned right from your phone and your ID could be checked. You can see screenshots for the process here: how to confirm your identity with Facebook.
ID Card (mobile web page) contains a link to your Facebook profile. So this mashup could be used also as a quick way for telling about your Facebook page to other people.
