1) Have 3 or 4 people arrive at say YYZ same day prior to your flight. They relay back what code they got and if they were sent to secondary.
2) Bad-guy 1 shows up with Bad-guy 2.
3) If Bad-guy 1 ones get code for secondary he lets Bad-guy 2 exit with the bag or vice-versa.
Yes, like most government tools, it is so antiquated. Plus you are asked not to fold the card, yet it does not fit in any shirt pocket. Bad design.
If it changes everyday, they certainly do mistakes.
They would simply have to had 2-d barcode on each card and relay the information from the immigration officer to the custom officer.
