Are there any widely used modern synonyms for turnstile? You know, the gate you need a ticket, badge, or barcode in order to pass through. Nowadays, I don't see any with an actual metal-pole turning mechanism, just a little set of doors that opens and closes when you scan your ID, so using the word turnstile seems kind of antiquated.
Example sentence:
"For our trip tomorrow, let's meet at the station just outside the turnstiles."
Except they're not turnstiles, because it's no longer a "post with a number of short poles sticking out from it that have to be pushed round as each person walks through the entrance" (https://dictionary.cambridge.org/dictionary/english/turnstile)
