Why Scan Barcodes in Web Apps?
Implementing your barcode scanning workflows in web apps offers unique advantages over native apps:
No Gatekeepers
No need to worry about App Stores and the headaches they bring. Host your web app anywhere you like, without platform risk.
Easy Distribution, Always Fresh
Distribute your app by sharing a link or a QR code. Web apps are always up-to-date.
Decrease Development Costs
Write your app once for the web instead of relying on expensive iOS/Android development. Avoid duplicating efforts and invest in a single code base instead.
Counter App Fatigue
Don't force users to install an apps they seldom need. App fatigue is real and it's is unlikely you need a native app, especially for business apps.
Rich Experiences
Progressive Web Apps (PWA) allow installing a web app on the user's home screen, increasing engagement and retention while offering advanced capabilities like offline operation and push notifications.
