* If you use Apple Wallet Passes, you could check your own gift card balance.
Customers can download Apple Wallet Passes to their iOS device from the notification email that they receive when they buy a gift card. Emailed gift cards will include an Add to Apple Wallet button. Customers can click the button to open the gift card automatically in Apple Wallet.
The Pass displays our store information, the gift card's active balance, and a unique QR code.
The example as below, for your reference:
Please check your mailbox ( that you used in this purchase) again, including the spams. And please make sure that our email address ( firstname.lastname@example.org ) is in your accepted list of mailing address, avoid it filtering as spams.
If needed, contact us to resend the gift card email to you.
