Samsung Wallet Promotions - what do I do with the vouchers?

[AndréUys]

On Samsung Wallet, I've been opting in to the promotions for a while now. When I tap to pay often enough, I get the vouchers - I currently have three for the Festive Promo. What should I do with these vouchers in order to enter? Do I need to mark them as used, or leave them unused?
