A computer system according to certain aspects uses past ticket usage data indicating a probability that a respective entity would personally use a ticket issued to them based on a history of past ticket usage. A ticket controller can respond to ticket requests by determining whether a ticket should be issued to a requesting entity based on the past ticket usage data associated with the requesting entity's profile, and if so issue a ticket to the requesting entity in electronic form. The system can receive a ticket use notification and update the past ticket usage data associated with the requesting entity's profile based on the ticket use notification, where the updated past ticket usage data conveys whether the requesting entity presented the ticket themselves.
