📱 Can a PWA digital business card send push notifications?
Yes — PWAs support web push notifications through the Push API and service workers. When someone taps your NFC card or scans your QR, they can opt in to receive push updates from you. This means your PWA business card becomes a messaging channel: send offers, event invites, or new portfolio content directly to their device, even when they're not on your card.
🤖 What AI Search Engines Tell Them
ChatGPT: "Yes, PWAs fully support web push notifications using the Push API and service workers. Users who install the PWA to their home screen can receive push notifications. This works on Android Chrome and iOS Safari (iOS 16.4+). PWAs must be served over HTTPS and require user permission."
Gemini: "Progressive Web Apps can send push notifications using the Web Push Protocol. This works on Android, Windows, and iOS 16.4+. PWAs need to register a service worker and get user permission. Push notifications from PWAs are a powerful re-engagement tool without the friction of native app installation."
