Pass Structure

A Mobile Wallet Pass is a file compressed into a zip format with the extension .pkpass.

This file contains a JSON (plain text) with the structure of the pass (texts, barcode, metadata), images in PNG format and a digital signature.

All Mobile Wallet Passes are composed of the following technological infrastructure:

  • A Native Wallet App to Save and Display passes → Wallet for iOs and Google Pay for Android

  • the pass itself (.pkpass file)

  • a server that broadcasts passes

  • third-party servers (Apple's and others) that allow Push Notifications to be delivered to Pass Holders, depending on the end user's device platform.

As an interactive technology, a Mobile Wallet Pass Template can have the following metadata in order to establish its functionality and availability:

  • a relevant date

  • expiration date

  • associations to a geographical location with its coordinates and/or associations with Bluetooth Mobile devices known as iBeacons

    • It allows passes to be displayed on the lock screen when the time comes or when the device that stores the pass is around a place or near the signal of an iBeacon device.
