When Passbook was first introduced with iOS 6, it opened with a page that gave users a quick way to locate and download Passbook-enabled apps. Unfortunately, the Welcome screen disappeared after a single Passbook app was downloaded, making it difficult to discover additional apps that used the functionality.
iOS 6.1 has made the Welcome screen a permanent fixture in the app, and it can now be found below other Passbook cards. Tapping the Welcome card opens a list of apps that use Passbook in the App Store.
Though Apple includes a Passbook section in the App Store, the newly permanent Welcome card provides a faster way to find Passbook-enabled apps.
Apple's Passbook included just a handful of apps at launch, but the service has proven to be popular with both users and developers. Apple's list of Apps for Passbook now includes more than 20 apps, including those from major retailers like Fandango, Target, Sephora, and Walgreens.
