In my 2 cents opinion, I never really believe in buying used thingy with unfilled warranty card, reason being, manufacturers nowadays are becoming very smart too...
1. Each product serial is 'encoded' with the 'estimated sale date' eg. Nokia Mobile... (I have personally encountered this)
2. Most manufacturers now request the accompany of the receipt together with the warranty card as proof of purchase. eg. Olympus... (I have personally encountered this)
Then again, it is up each individual...
That's true not only for Nokia handphone. It's similar to batch no, each product belongs to a certain batch produced at a certain month of the year.
When the retailers or authorised distributors take in more stock from the manufacturer, like Nikon...etc
It is reasonable to assume that they have sold off the previous batch hence the need to re-supply.
So the manufacturer can estimate when you roughly bought the product though this may sometimes differ by a few months.
My Nokia phone was bought from Starhub on April 01, it had a bad crack and was sent to Nokia Care on June 02, as it was "out of warranty" being longer than 12mths from April 01.
However at Nokia Care, I told them I did not have the receipt and they checked my phone's IMEI no.
When they printed the invoice, the indicated warranty expiry is June 2002 instead, so I had an extra 2 months warranty free.
I assumed the "estimated sale date" was June 01. and the system hence computed my warranty expiry as such.
