Using wallet as a rewards card key ring

Hi winipig,

Their are several ways you can use Wallet without needing specific apps. You can add passes into your wallet, which act like "key ring cards" you could say, using wallet enabled apps, with mail or messages, from a web browser, scanning a barcode, sharing through AirDrop, from your Mac, or using a reward card and paying with Apple Pay. Please note, some apps, or merchants may not support the wallet feature.

I hope I've helped solve your question today. If you have anymore questions, or concerns please don't hesitate to ask! 🙂
