In September MobileMonday reported that China Mobile offers train e-tickets with QR-Codes. I checked CTTL for an update, but didn't find anything. Does anybody know if they already started?

China Mobile plans to test a train ticketing system using its bar code e-commerce service QRcode in Beijing in October, reports National Business Daily.
With the correct handset QRcode, users can get on trains without having paper tickets.

I suppose it is not so much the direct code scanning which plays a major role but rather receiving a WAP-Push link via SMS to get a QR Code ticket on the device.
