Vita used cards, not cartridges.
I think old people calling cards "cartridges" is the new uninformed people calling cartridges "tapes."

Some Switch owners insist on calling the Switch game cards "cartridges" even when it says "card" on the slot.

Nothing important, just a 30-year-old pet peeve of mine =)

I'd say there's a very important distinction there. They are totally different technologies.
