You really cannot expect Metrolinx to keep track of peoples' ages! A card can be used by anyone; if you are 65 or older you can use a card that is set for Senior Fares; if you are less than 13 (No charge up to 13th birthday) you can use a Presto set for Child. It would, obviously, be better if the Child and Adult (and teenager?) cards LOOKED different and MLX could do this by charging $6 for a Child's card but then exchange it (at no cost) for an adult one or a "Teen" card which, in time, could be exchanged for an Adult one. We have two cards in our household, one Adult, one Senior and it is up to US to make sure that only a Senior uses the Senior one. (We can do this visually because we have a Black card for Adult fares and an older Green one for Seniors. ) Though it would not matter to TTC if a Senior used the Adult card - they would get the full fare - but for a customer it would actually make sense if MLX had four card designs/colours. Child, Youth, Adult, Senior and would exchange one for another at no cost when its user reached the requisite age milestone. Dream on, indeed! Of course, as more and more people pay for transit with credit/debit cards or apps the use of specific Presto cards will decline but ....
The fare inspectors would see an indication on their scanners on who is eligible for a discount or free, when they scan the cards for proof of payment. Unless the student has grey hair, they'll then be asked for proof of age.
