The Dollar Store used to carry a thin, two-sided pleather and clear plastic cardholder that was perfect for flipping open to show a Metropass and Support Person card at the same time. It was safer than taking out a wallet with debit cards, etc. each time you have to take TTC. Anyone have other ideas?
If the person doesn’t mind the sensory feel of having a lanyard around their neck, there are some ones with nice patterns on them at the dollar store. A lanyard with a plastic pocket on it could store the TTC cards. They could tuck it in their shirt or jacket when they didn’t need to show it.
