Name checking on SQ Points Credit

[sydunipete]

I recently had some points credited to my SQ KrisFlyer account that weren't mine. Given the flight legs they were obviously flown on a partner airline. The points were subsequently reversed. I presume the flyer just quoted a wrong SQ KrisFlyer number to the airline.

Does anybody know what checking happens when a passenger quotes a number to a partner airline and before it is credited to an SQ account?

Thanks.
