A ticket exchange server is configured to monitor seat usage in a stadium during an event. The ticket exchange server provides a first ticket for a seat to a first client device in response to a request from a first user of the first client device. The ticket exchange server unlocks the seat in response to detecting a presence of the first user at the seat. The ticket exchange server receives an indication from the first user surrendering the seat prior to completion of the event and locks the seat. The ticket exchange server provides a second ticket for the seat for a remainder of the event to a second client device of a second user in response to a request for the seat from the second client device. The ticket exchange server unlocks the seat in response to detecting a presence of the second user at the seat.
