Question from one of our juniors who got an Air Card for Christmas: How do I claim those results and keep the older ones too? Is there a way to hold more than one card as "owned"?
If you go into results from a meet that they went to and find their name, they should be able to click on the question mark next to their name and claim the results by entering the SI number. In that process there is a way for them to say whether they own the card/stick or if it was borrowed for that day, and, depending on that, AP will attach all the results with that number to their AP, or just the one result if it was borrowed.
If they change their card number, the results from previous cards/sticks will stay linked to their log.
Hope that helps!
I've not seen the option to claim two lots of numbers as a permanent thing. Claiming results for a particular event seems to allow you to claim just the one result (though I notice the last time I did that it also went back and claimed results for previous events where I didn't want it to, e.g. when I ran a second course with my second stick) or else override your primary stick number in AP, in which case you then have to manually claim results for your former, primary stick (I think).
However it is correct that previous results will also remain "claimed".
