Received the box. Inside box there's this white card. The card has a QR code behind it. By scanning the QR, SMS is sent to pinelabs (I guess) to activate the gift card code. Once it's activated, the code can be added to the Amazon pay balance. The gift card code is hidden and needs to be scratched. It's safe, one can order. Just remember to open the box in front of the delivery guy, ensure that the code is not scratched. I could add 10k successfully.
