The App Clip experience for NFC.cool Business Card got a substantial polish pass:
Frictionless save. Recipients see your card in a native iOS sheet and can save to Contacts in a single tap.
Tighter NFC handshake. The AppClip payload is verified and the card content prefetched before the sheet shows.
Apple Wallet route. Visitors can drop your card into Apple Wallet for instant access later.
Visitor privacy preserved. Save events are recorded as anonymous counts only - no visitor identity is captured.
Background context on the architecture (App Clip + SwiftUI + secure backend APIs) was the subject of a mDevCamp 2025 talk in Prague.
