Hong Kong's Octopus card uses Felica, as far as I know.

It's conceptually very similar to MIFARE – a fixed function IC implementing a fully offline stored value purse – but uses a stack that differs from ISO 14443 A on pretty much all layers. (It was planned to possibly become ISO 14443 C, but that never happened.)

Yes: Felica was developed by Sony in Japan, but was actually first adopted in Hong Kong, then later in Japan. It's far better than other standards, because it's so fast.
