Adding an NFC card to your profile

On the NFC Cards tab of Profiles, click "+ Get an NFC card link" to claim one. Card links are included on Team, one per member, and let you use an NFC card or tag you already own. A link points at your primary profile by default, and you can reassign it to any of your profiles from the same tab at any time, with nothing to re-encode.

Physical NFC cards, tags and stickers are ordered from the Shop in the sidebar, work on every plan, and are listed under NFC tags once you have them. Once one is set up it works the same way: the tag encodes a stable link, and which profile it opens is something you control from Profiles, not something baked into the hardware.
