PassWallet - Passbook is an app that gives you an easy way to easily store all the tickets, admission cards, boarding documents, coupons, and other documents in passbook format (.pkpass).
Any passbook file saved to your device will automatically load in your PassWallet so all you have to do is wait a few seconds while the documents are uploaded and synced to your device.
PassWallet - Passbook's interface is a bit rough but it still works well. From the drop-down menu off to the side you can easily access all your tickets. You can even view a map that shows you the exact location related to each ticket.
PassWallet - Passbook is a very useful tool for frequent travellers, as nowadays the digital format is accepted for most plane and train tickets.
