According to a post on WPCentral.com, Microsoft’s new Windows Phone 8.1 software allows Apple Passbook passes to be used natively. When a user chooses to download a Passbook pass, it will be downloaded to the Microsoft Wallet application, and can be used as if it were on an iPhone or iPod touch. It’s unclear what specific Passbook features are supported, or if Apple will put a stop to the process.
