Mine doesn't match either and I got it from the store 2 weeks ago.
Wow, I had no idea they even came with one! Didn't know they had serial numbers either - where is it? Does each bag come with a unique serial number or does it just give model/production date info? I purchased mine directly from PS in NYC and I don't remember seeing any auth. card like the one you pictured.
ETA: Beautiful bag, BTW!
Thank you
I remember someone saying that PS started including auth. card since fall/winter 2013. So, if you purchased before then, it wouldn't have the card.
Thank you! I noticed a lot of people claimed that theirs do not match, so I guess it is intentional?
