day pass

A transit pass (North American English) or travel card (British English), often referred to as a bus pass or train pass etc. (in all English dialects), is a ticket that allows a passenger of the service to take either a certain number of pre-purchased trips or unlimited trips within a fixed period of time.
Depending on the transport network and on how much the pass is used, the pass may offer varying discounts compared with trips that are purchased individually. While transit passes can generally be purchased at full price by anyone wishing to use the services (senior citizens, tourists, the disabled, students and some others are often able to get them at a reduced price) many employers, colleges, and universities will subsidize the cost of them, or sometimes the full amount.
Some public transport networks will allow certain types of personnel, including police officers, fire fighters, active military, and their own employees to ride their services free with proper identification and without the need to purchase a pass. In a lot of cases, the identification can be scanned on the ticket validator like any other transit pass.
