Thank you for your consent

The packet I received from TD with my new credit card is headed: "Thank you for consenting to your TD [blah blah] Card." Though I know that that's based on recent scandals involving people being signed up for bank services without their consent, it still seems like a remarkably negative way of putting it.

Also, I consented to receiving services from the bank. I haven't consented to the card itself. What does this card have in mind? Do I need a safe word? The PIN is probably not appropriate / sufficient for that purpose.
