The Update: You can now use the Skycore mobile marketing platform to create and send Passbook® passes to phones that do not support the Passbook or PassWallet app. Instead of immediately launching a .pkpass file, we can detect if the mobile operating system supports Passbook. If the pass is distributed via landing page, when the Passbook is not supported, instead of showing the pass download button, we render the pass in CSS and HTML on the landing page. We also include a button prompting the recipient to bookmark the page or download a Pass viewing application like PassWallet. If the pass is delivred via MMS or email, the normal pass button will show, but when clicked by someone without Passbook, the button leads to a landing page displaying an CSS/HTML pass.
The CSS and HTML version looks almost exactly like the .pkpass file version does with a front and back of the pass containing pass data. The CSS/HTML version also updates itself when the data is updated so it can be used as an alternate replacement. The only feature lacking from the the CSS/HTML version is that it will technically not be able to provide location notifications to a user who has bookmarked the application.
The Benefits: While many smartphones have apps to display Passbook’s .pkpass file (or natively display them, in Apple’s case), some operating systems still lack decent pass viewing applications. Now any phone with a browser can display the Passbook passes.
