If you’ve already pledged to this project, click the “Manage My Pledge” button at the top of the page. If not, click “Back this Project” and pick one of the rewards. Every backer can pick one and only one reward level.
Whenever you lose your wallet and it's out of range, you can use the user network and track your wallet through another user's range. When you mark your wallet as lost on the app, you'll be notified when another user is in range.
