This is an Uber Voucher, and not a Gift Card. The key differences are:
- Gift Cards add funds to your Wallet, while vouchers are a separate payment method altogether. These funds do not get applied to your Uber Wallet.
- The Vouchers always get used first as a payment method. If you apply a voucher, this will get used by default, rather than other payment methods you have enabled.
- The Vouchers are only supported on Mobile at the moment. The desktop mode currently doesn’t support vouchers.
- The Vouchers are applied to your account by following a link. This should be done on mobile. It can be done on a computer if you are already logged into your account, although the balance may not be viewable until you check on mobile.
