I dunno about the UK, but I think RFID readers might just be cheaper because they require so little maintenance.

I bought a single-use one-way subway ticket recently. When I got to the turnstiles, none of them had slots to swipe or insert the ticket.

Of course, it's 2023. You can tap the paper ticket as if you had a refillable or monthly pass, it has the RFID circuitry sandwiched between paper layers. No more mechanical moving parts which can break and slow down the rush hour commute.
