App Clips (iOS)
A small, fast, launch-on-demand slice of your full app — invoked from a URL (NFC,
QR, App Clip Code, Safari banner, Maps, Messages) without an App Store install.
For a fintech app the common uses are pay-at-table, scan-to-pay a merchant code,
onboard-a-card, or claim-an-offer, then hand off to the full app. Grounded in
Apple's AppClip framework, StoreKit, and App Store Connect docs (iOS 26 era).
- Deep links / associated domains: an App Clip is Universal-Links machinery narrowed to one target; see
deep-linking. - Secure handoff: shared secrets go through an App Group container or CloudKit, not the Keychain (App Clip Keychain items are not readable by the full app) — see
swift-security,cloudkit. - Writing physical tags: encode the invocation URL on an NDEF tag with
core-nfc. - Purchases inside the clip: StoreKit works in a clip — see
storekit; Apple Pay viapasskit. - Submission gates: privacy manifest, size, entitlements — see
app-store-review.
