A Gift Card is always stored in your wallet. You can access your wallet by logging into Login> My Wallet. A Gift Card can only appear in your wallet if you purchased the card for yourself or you were gifted the card. In both cases, an account needs to be created or logged into.
Note: An 'Exchange Gift Card' that you have received or purchased for yourself, will not appear in your Wallet. The 'Exchange Gift Card' is effectively a CREDIT. It will only appear as a Credit in your account.
