# Real-World Payments (Apple Pay / Wallet / Tap to Pay)
**You MUST use this skill when accepting ANY real-world payment — physical goods, services, donations, ticketing, loyalty cards, contactless card-present, or post-purchase order tracking. NOT for in-app purchase or digital content.**
## When to Use
Use this skill when you encounter:
- Adding Apple Pay to an iOS / iPadOS / macOS / Catalyst / visionOS / watchOS app
- Adding Apple Pay to a website (Apple Pay JS or W3C Payment Request API)
- Building Wallet passes (boarding passes, event tickets, coupons, loyalty cards, store cards)
- Accepting contactless card payments on iPhone (Tap to Pay on iPhone / ProximityReader)
- Surfacing post-purchase order tracking in Wallet (Orders in Wallet, FinanceKitUI add-order helpers)
- Issuer or bank card provisioning into Wallet (issuer extensions)
- Apple Pay merchant ID, processing certificate, or merchant identity certificate setup
- Pass Type ID or Order Type ID certificates and PKCS #7 signing chains
- Tap to Pay managed entitlement (`com.apple.developer.proximity-reader.payment.acceptance`)
- App Review rejections that mention payments, IAP, Apple Pay, Wallet, or Acceptable Use Guidelines
- Domain verification for Apple Pay on the web (`.well-known/apple-developer-merchantid-domain-association.txt`)
- Sandbox testing with Apple Pay sandbox cards or sandbox tester accounts
## When NOT to Use
| Issue | Correct Skill | Why NOT axiom-payments |
|-------|---------------|------------------------|
| In-app purchase, subscriptions for digital content | **axiom-integration** | StoreKit 2 / digital goods boundary; see `axiom-integration (skills/in-app-purchases.md)` |
| Generic NFC tag reads (Core NFC, non-Wallet) | **axiom-integration** | Different framework; PassKit NFC is Wallet-specific |
| Code signing / provisioning fundamentals | **axiom-security** | Code signing is generic; payment certs are *added* to that flow |
| App Store rejection workflow & appeals | **axiom-shipping** | Rejection workflow lives there; payment-specific rejection patterns route from there into here |
| HIG cross-cutting design guidance | **axiom-design** | Apple Pay / Wallet HIG specifics live here, but design overview lives in axiom-design |
| Consumer banking surface (FinanceKit) | *Out of scope* | This suite uses FinanceKitUI only for Orders. Account aggregation / transaction queries are not covered. |
| PKSecureElementPass, transit cards, car keys | *Out of scope* | Issuer-controlled, not relevant to merchant developers |

Simplified routing:
1. Is this a digital good or subscription for digital content? → **Use `axiom-integration/skills/in-app-purchases.md` instead.**
2. Selling physical goods / services / donations, or unsure? → `skills/apple-pay-vs-iap.md`
3. Native Apple Pay (iOS / iPadOS / macOS / Catalyst / visionOS / watchOS)? → `skills/apple-pay.md` + `skills/apple-pay-ref.md`
4. Apple Pay on the web? → `skills/apple-pay-web.md` + `skills/apple-pay-web-ref.md`
5. Tap to Pay on iPhone (ProximityReader)? → `skills/tap-to-pay.md` + `skills/tap-to-pay-ref.md`
6. Wallet passes (ticket / coupon / loyalty / store card)? → `skills/wallet-passes.md` + `skills/wallet-passes-ref.md`
7. Orders in Wallet (post-purchase tracking)? → `skills/wallet-orders.md`
8. Issuer / bank card provisioning? → `skills/wallet-extensions-ref.md`
9. Something not working (no sheet / merchant validation fails / pass won't import / Tap to Pay never enables)? → `skills/payments-diag.md`
## Cross-Suite Routing
**Apple Pay vs IAP boundary** (the most common cross-suite question):
- Selling physical goods, services, or donations → **stay here** (`skills/apple-pay-vs-iap.md`)
- Selling digital content, premium app features, subscriptions for digital content → **use axiom-integration** (`skills/in-app-purchases.md`)
- App was rejected for using the wrong one → `skills/apple-pay-vs-iap.md` then `skills/payments-diag.md`
**Payments + App Review rejection**:
- Rejection cites Section 3.1 / 3.2 / Apple Pay AUG → **stay here** (`skills/payments-diag.md`) for the root cause; **also invoke axiom-shipping** (`skills/app-store-diag.md`) for appeal workflow
**Payments + cert management**:
- Merchant Identity Certificate, Pass Type ID Certificate, Order Type ID Certificate, Payment Processing Certificate — operational discipline → **stay here**
- Generic Keychain export / `.p12` mechanics → **also invoke axiom-security** (`skills/keychain-ref.md`)
- Tap to Pay managed entitlement → **stay here** (`skills/tap-to-pay.md`); generic managed-capability mental model → axiom-security (`skills/code-signing.md`)
**Payments + Xcode capability / provisioning**:
- Apple Pay capability checkbox in Xcode, merchant ID selection, Tap to Pay entitlement plumbing in the provisioning profile → **also invoke axiom-build** for capability/profile mechanics; payment-specific guidance stays here
**Payments + HIG**:
- Apple Pay button vs Apple Pay Mark, Wallet pass design specs, Tap to Pay button label → **stay here**
- Cross-cutting design context → **also invoke axiom-design** (`skills/hig.md`)
**Payments + Catalyst / macOS**:
- Apple Pay on Mac and Catalyst (window requirement, web security model, static merchant validation URL) → **stay here** (`skills/apple-pay.md` Catalyst section)
- Generic Catalyst patterns → axiom-macos
**Payments + Apple Watch**:
- WKInterfacePaymentButton, watchOS payment delegate flow → **stay here** (`skills/apple-pay-ref.md` watchOS section)
- Generic watchOS patterns → axiom-watchos
