Owner warranty registration

[Bali]

Hi, 
I just bought an amazing, brand-new Vigier guitar yesterday. 
The only document I found in the bag is the 'Owner warranty registration' sheet. Is it the only way to register my warranty if I send this paper back to France from Asia? Isn't there a faster and more contemporary (digital) way to do this? 
Thanks for your help

Thank you for your trust in Vigier
What counts is your purchase invoice from the store. You do not have to return anything.

I understand and thank you for the fast reply. 
One more question. Where can I find the manual for the Doublefoot?
