Here's how to move gift cards from "spent" back to "active".
Find your previously purchased codes in the Fluz App through the Menu button (☰) on the top right, then click "past purchases". Your spent gift card will be under the "spent" tab.
Click on the gift card you want to check. When prompted, enter 4 digit passcode.
Click on "Update Balance" found at the bottom of the screen. Press "undo", then "update", then "done". The gift card will now be moved back to the "active" tab.
This tracker only helps you keep tabs on your gift card balance. The actual amount in the gift card may differ. To check the actual gift card balance, you can google the gift card balance checker of your specific merchant. Please enter the gift card number and pin shown in the Fluz App.
