Is it possible to store hidden fields in Passes? (iOS 6.0 Passbook JSON)

I want to store hidden values in the JSON file, which aren't displayed in the passbook, but can be accessed from my app after I loaded my passes like this:

[_pass localizedValueForFieldKey:@"hidden_field_1"]

With the new iOS 7.0 API it is possible with the userInfo key. For more information, read the documentation

Since the pass serial format is arbitrary, you it might work for you to append the (short) data to it.

normal serial          serial with data

00001                  00001|laskjfrg645sa
00002                  00002|a654sf6s54fas64
00002                  00003|a6sd5f4a46sdf5

As you are in control of the "id" part, the serial will always remain unique.

Anyway, while it probably works, it's not very kosher.

According to my reading of Passbook Programming Guide all fields are displayed. Users are supposed to know what is being stored in the pass so they aren't afraid to accept it. You might consider using the backFields to store a encrypted string with a label that says something like "Verification tracking field".
