Offline-first architecture
Online sign-in
Only features that inherently need the online network need a sign-in: Tap to PayCard acceptance on a phone via NFC, through a certified payment-provider SDK. Planned as an adapter; Simca does not read or store card numbers. Glossary, the co-op price counter, referral validation and the Logistics board relay. Selling never requires sign-in.
Designed in a document, no code yet
What to plan for
- Sign-in method not decided
- Disclosure screen
- Offline-first fallback
