Confirming that e-Channel worked at PEK for EXIT (two weeks after signing up).
The attendant did take one look at the length of my nose, and was first wanting to direct me back to the other passport check area. But I insisted and she eventually let me through.
(No pre e-channel passport machines anymore!)
I think my passport has readability issues as it took a few goes to read it - had this happen in other countries too, so not a unique experience.
(They did confiscate my USB car charger, as they felt the +12V tip was too 'weapon like'. 😃
Will be interesting to see if it works on entry in a month or so.
