Mo more tickets!
.
Alice enters a movie theatre, takes a seat, enjoys the show and leaves the theater. At no point in time has Alice purchased a ticket or given any money to a teller.
How does this work
By walking into the entrance hall of the theater, Alice starts an eGo pairing between the theater info system and her eGo. The eGo pairing done, there is a data channel of communication between the eGo compliant device (the theater info system) and eGo. Alice can look for her seat on the info panel and change her seat. The UWB based location service allows verification of seats with the electronic ticket (notifying of the wrong seat or no ticket).
