## 3. Priority Gap Themes (Recommended Sequencing)

| Priority | Theme | Key Gaps | Rationale |
|---|---|---|---|
| P0 | Card-rail readiness | Network tokenization, 3DS/SCA on payments, scheme integration, PCI DSS | Blocks Apple/Google Pay and any real card issuing at scale |
| P0 | Payment completeness | Request money, scheduled/recurring payments, customer scan-to-pay QR | Table-stakes wallet UX Way4 ships out of the box |
| P1 | FX & cross-border | Live FX rates, rate locking, cross-border rails | Differentiator for GCC remittance corridors |
| P1 | Credit expansion | BNPL, installments, pre-approved loans | Monetization; loan engine foundation already exists |
| P2 | Agent network CICO | Agent onboarding, float, commissions | Financial-inclusion reach beyond branches |
| P2 | Engagement | Coupons, referrals, PFM analytics, personalized offers | Retention; rewards foundation already exists |
| P3 | Acquiring stack | POS switch, e-comm gateway, merchant payouts | Large build; consider partner gateway instead |
