Dear Huzaffa,
Thanks for confirming that I can safely fax a copy of my CC, I'm quite reassured now.
Accordingly, I've just faxed a copy of my Caisse d'Epargne VISA card to PaisaPay at +91 22 5669 0001. However, I wonder if it will be OK, because the prints on the card are barely readable on the copy.
Anyway, I'll see.
Best regards
Nathalie
