Like the rest of the population.

Or thru ApplePay (if not a pipe dream).
I can't speak for all places, but I've seen Quickpass branding all around. Others have reported issues using the US based UnionPay card, but I haven't had any hiccups the few times I've used it. I might try on the Metro later today.
