Wallet Pass is an app that allows to load passbook files (pkpass) in a Windows Phone and show them in almost their original way. Every passbook can be saved in the app and in the wallet.
In trial mode passbooks can be opened to show them, but not save.
If you want to add your language to the app, feel free to contact at

If you have problems with any passbook or any question, you can contact and send pkpass files to wallet_pass_support@outlook.com
