After you make a purchase, you will receive a confirmation email from EventSprout. Inside your confirmation email, there is a button that says "View Tickets". Click that to pull up your ticket.
You can also view your ticket by logging into your EventSprout account, clicking on the event, and picking "View Ticket".
Unless otherwise stated by your Event Organizer, EventSprout tickets can be scanned from your mobile device or can be printed.
