Apple's Passbook passes are being used by Windows Phone 8.1 and Microsoft Wallet
When Apple introduced Passbook apps, passes, tickets, help, and how-to") in iOS 6 they billed it as a way to store all your tickets, coupons, boarding passes, loyalty programs, and other cards all in one place. It's hard to imagine they expected that place to one day be Microsoft Wallet, but thanks to Windows Phone 8.1 that appears to be exactly what's happening.
