No I trust my employees to activate it. Keep the receipt and if it don't work go back or call Nintendo.
im just scared about them not activating itThis.
You pretty much can't screw it up after that. Unless you're an idiot and got a scratched card, as long as they activate it I've literally never heard of any problems ever with any prepaid card. Ever. Just non-activation problems. But not to say something bad can't happen. But it seems pretty fool proof.
Tbh if anyone is really paranoid, just take the stack of cards off and pull from the middle.
