Your NFC card

A wooden card. Held against a phone, your Straby card opens. Nothing to install, on either side.

Activate it. "My cards", then "Add a product", and the code printed on the packaging.

Use it. Hold it against the upper back of the phone, screen on. On iPhone it works from the iPhone 7 onwards. On Android, NFC must be enabled in the phone settings — that explains almost every failure.

Reassign it. From "My cards" you can point the same card at another of your cards. Useful when you change roles, or lend it for a trade show.

Disable it. A lost card is disabled from the same screen and opens nothing afterwards.

How many. One per person. Teams usually order one per seat, with the leader activating them before handing them out.
