All Moscow public transport powered by these chips (actually it was, nowadays the chips we use are clones, made in Russia itself) - trains, metro and buses.
For a few years now, you may usually do a contactless card payment - just tap your bank (debit or credit) card. The fare is often higher but so is convenience.
Back around 2010 I remember reading these accusations that significant part of revenue went directly to Mifare for the massive number of chips.
And for single rides, some of Metro systems still use these steampunk brass tokens. Sometimes, less authentic plastic.
In the systems I’ve ridden, there’s usually some kind of plastic stored-value card for regular riders, and the (more expensive) disposable tickets are only used by occasional riders.
