Provide a fixed-scope audit that tests the operator's critical access journeys across a managed inventory of older and current phones. Reproduce failures involving installation, login, identity verification, ticket acceptance, wallet display, camera scanning, Bluetooth, and geolocation, then deliver prioritized fixes and documented fallback procedures for customer support and venue staff. Begin as an expert testing service and productize recurring regression checks and compatibility certification after establishing repeatable test cases.

Mandatory digital ticketing is colliding with frequent operating-system changes, aging customer devices, and increasingly complex identity and location controls. The evidence shows that failures are preventing completion of the core transaction rather than merely creating cosmetic inconvenience.
