Pass2Pay is a tool for the importation of passbook files, which contain all the information needed to get a pass or ticket to your device. It is designed to be used with a PDF or image of the pass you want to add, so you can create them directly from your phone or tablet.

You can add all kinds of passes: those issued by the government, those from private companies, and those for private use. In addition, you can add transport tickets, loyalty cards, gift cards, and the like.
