Yes, you can link a Spriggy card to an Apple account and the App Store
Just check that you have money on the Spriggy card before you start because Apple often requires a pre-authorisation. This means Apple will debit $0.01 to $1.00 from your card to check that your card is active. The amount will be refunded within a couple of days. If your card balance is $0, your card may be rejected.
Setting your card up on the Apple and the App Store is different to ApplePay. See this guide for help with ApplePay.
