This November, #AnimalCrossing #amiibo Cards Series 1-4 make their return to select retailers. Use the amiibo cards to invite characters to live on your island in Animal Crossing: New Horizons, as well as other features!
Sadly the home data from HHD or the level data from AF doesn't do anything in NH so the only thing to use the amiibo for in NH is inviting villagers to the campsite of Harvey's island.
No news on a Sanrio or Welcome amiibo series restock.
If you just want the cards for inviting animals and have an Android phone with NFC you could lookup ways to just use your phone I think.
