на какой такой "проезд"?

"проезд" here means a ride in public transportation.

"here" here means "in Russ' translation", not in the Russian text. About the latter we can only guess.

Да и clipper в русском варианте - это скорее билет/карта, чем пропуск.

Clipper is a plastic electronic card used to scan when passengers enter public transportation vehicles (bus, tram, subway...) And I think this is what Natalia was asking for.

And I think she meant the latest events in Moscow. As I said, it's билет/карта in normal life.

Yes, it's very annoying that people, when asking, can't be bothered to think a little whether the question is clear enough or needs additional information/context.

I’ve never heard of a plastic card called a CLIPPER - where is it used?

Ah, it seems it’s only used in San Francisco: https://en.wikipedia.org/wiki/Clipper_card
