Ticket (admission)
paper or cardboard document showing payment for access to an event or service
A ticket is a piece of printed paper that gives you the right to enter somewhere or do something. Tickets are often used as proof that you have paid for public transport, theaters, cinemas or sporting events. Tickets often display printed information like serial number, barcode, price, expiry date, seat number and class of ticket.
Sometimes, you have to take a ticket, such as at the start of a toll road, to help calculate how much you should pay the at end of your journey. Some tickets are becoming electronic barcodes, and are displayed on a screen instead of paper.
