How do I enable my senior discount on this for NYC metro subway?

Hi there JP2030,

If you've successfully added your transit card to your Apple Wallet, this article explains all the ways you add money to refill it: Top up your transit card with Apple Pay

If you are not seeing an option to use your discount, then we would recommend reaching out to your local transit agency to see if this is possible to do with a transit card in your Apple Wallet. They would be the best-equipped to answer this question.

Cheers!
