Tap the card, enter the amount, show or enter the code.
First, tap the retail card you'd like to spend with from either your home screen or wallet.
Next, enter the exact amount you'd like to redeem from the retail card, show the retail specific code (as shown in the borofree app) at the checkout or enter the code online then tap confirm.
Your new estimated balance will then be updated by you ready for the next time.
If you've redeemed the full value of the retail card, you can add it to your archive as a record of your card purchases.
