DP: I was able to satisfy the requirements by providing them with my Canadian-issued APEC cards*. The officer just scanned my PP and APEC card and the renewal process was done in two minutes.
*FYI these aren't technically eligible because US and CA are transitional APEC members.

Eligibility Criteria

Holding one of the following valid documents:
- HKSAR Travel Pass;
- APEC Business Travel Card with ‘HKG’ printed on the reverse side; or
- Frequent Flyer Programme membership card issued by airlines which have joined this scheme (please enquire with airlines for details).

Mine certainly did not have HKG printed on the other side. So take that for what you will.
