I thought contactless is considered too slow? The exit gates are often open and only close when somebody attempts to pass without their IC card/insufficient balance on the IC card, how does this work with contactless?

I feel like they could combine the IC and contactless reader into one bit of hardware with some engineering.

This is the case in the Netherlands. The same readers accept the old OV-chipkaart (stored-value) system and the new OVpay (EMV) system.

Actually, I feel like when the OVpay system was rolled out, the existing OV-chipkaart readers simply got a firmware update, giving them the ability to read EMV cards and phones.

Both of these systems work across all tranit modes and operators in the entire country (and even at a few stations across the German border), and there are various models of reader that are used.

(note: OV = openbaar vervoer = public transport)

They've gotten NFC VISA payWave at least comparably fast as FeliCa by skipping a few checks. It's still not as fast as genuine Suica - look how hard these men force their own fist to stay on the reader like their pay depends on it[1], but Suica advantages are slowly becoming a tougher sell with population and economy going a long way down.
