Once you use the cards, you can let someone else scan the card or whatever right? Do you have to keep tapping each time you wanna access the content or you set it and forget it? Thanks
Yes, you can lend the cards to friends to unlock the content. And once you've scanned a card, the items it unlocks (furniture, wallpaper, flooring, clothing) stay unlocked within the shopping menu in the game. To scan all six cards in one day to unlock all the items, you use the Nook machine to scan an amiibo, but then tell the machine you don't want to invite them to the campsite and you can then scan the rest.
And if you want to use the card to invite the associated villager to your island, you have to invite them on three separate days, and each day craft for them the item they ask for. On the third day, they will agree to move to your island and will replace a villager of your choosing if you are already at max capacity. But you only need to scan once to get the items.
