Updating digital passesThe combination of pass type identifier and serial number is used throughout PassKit to uniquely identify a pass.

Goal
The aim is to learn as much in other to establish a re-usable template for other NHS services
Why
We have a series of user journeys on the NHS app which needs to work offline
Hypothesis
