PWA Technology: Why Your Digital Card Works Like a Native App
When someone receives your Scaanme digital card, they can install it directly to their phone's home screen, just like a native app. No App Store, no Google Play, no download wait. This is PWA (Progressive Web App) technology, an open standard defined by the W3C Web App Manifest specificationW3C Web App Manifest specificationhttps://www.w3.org/TR/appmanifest/ that enables web apps to function with native app capabilities.
What Is a PWA?
A Progressive Web App is a website that behaves like a native mobile application. It can:
- Install to home screen with an icon, just like any app
- Work offline using cached data
- Load instantly without app store delays
- Send notifications (where supported)
- Update automatically without user intervention
Why PWA Matters for Digital Cards
| Feature | Regular Website | PWA |
|---|---|---|
| Home screen icon | No | Yes |
| Offline access | No | Yes |
| Loading speed | Depends on connection | Near-instant (cached) |
| App store needed | N/A | No |
| Auto-updates | N/A | Yes |
| Full-screen mode | No | Yes |
How It Works with Scaanme
- Someone scans your QR code or taps your NFC card
- Your profile opens in their browser
- They see an "Add to Home Screen" prompt
- One tap and your card is installed as an app icon
- Next time they need your info, they tap your icon, loads instantly, even offline
