I already run a Node.js service that takes an 8-digit barcode from a customer, generates an Apple Wallet / Google Wallet pass, and hosts it under my current Apple and Android developer accounts. The passes are live and in daily use. Phase 1 is urgent: move the existing Apple Pass certificate to a new Apple Developer account without breaking a single live pass. After the hand-over, all previously issued passes must keep updating exactly as they do today. (Please see the attached picture of the existing Apple Pass), Phase 2 extends the platform. I want a simple way—ideally via an admin UI or a config file—to refresh the look of every pass on the fly: • Colours, logos, and overall layout must be editable. • Specifically, background and text colours need to change; the barcode area stays untouched. • No fixed colour codes: just stay consistent with our current brand palette. • When I hit “save”, every stored pass (existing and future) should pick up the new styling automatically through PassKit / Google Pay updates. * Currently, we are not maintaining a Database of the passes issued, but prefer to do so. Not Mandatory You’ll be working inside a clean Node.js code-base already wired to PassKit and the Google Pay API. Deliver working code, migration instructions for the certificate move, and a brief read-me covering how to trigger appearance updates. Smooth continuity for our users is the yardstick for success.
