Ticketize - ID Scanner

Organizing conferences, seminars, lectures and other events poses
several major organizational difficulties for the organizing party relating to
the registration of the visitors, attendance tracking and after-event
statistics.
Ticketize is an app to track attendance at events and lectures.

On the one hand, the event organizer can scan visitors' tickets using the app. Either you're organizing an event, or you have a small museum, or you're just organizing a party night for 100-something, Ticketize will let you invite and create tickets for every single one of them.

On the other hand, students can check-in at their lectures. You can save your personal ID, point your iPhone at the lecture's ID.. and that's it! You've checked-in!
