We are aware that if you're under 16, but look older, it can be a hassle proving your age when using public transport. The U16 card takes care of that. You can use it to get a child fare when paying cash, or you can use it when buying child rate season tickets.
Then you could be eligible for the 16-18 photocard which entitles you to child rate season tickets or child fares to and from school or college within the Network West Midlands area.†
† Not valid for purchase of child rate day tickets ie. one day child network daytripper or child daysaver etc or for the purchase of off-peak tickets for travel outside the Network West Midlands area. It is the responsibility of the individual to ensure that they have the correct photocard for their age.
