Many organisations now issue electronic tickets as a pdf with QR code. These cannot be stored in AppleWallet without being in .pkpass format. Some organisations such as airline tickets are issued .pkpass capable.

Although several (possibly non trustworthy?) small software apps exist to create a .pkpass format from PDF, it would be beneficial for users to be able to do that from Acrobat as Creative Cloud Users.

Paper tickets should not be necessary wherever possible

Thanks.
