A small automated validator usually mounted on buses, trams, or station platforms that physically marks a paper ticket. Passengers must insert their unvalidated tickets into the slot before beginning their journey to prove the fare is active. Transit inspectors check these timestamps to ensure riders are not reusing old tickets or traveling beyond their allotted time limit.

Make sure you run your pass through the ticket stamping machine before you get on the light rail, or the inspectors will fine you.
