Hi @Ayoub,

I guess this Qr Scanner is the one that in the marketplace?

As far as I’m aware that don’t work with PWA and only in Native.

There are two Qr Scanners that works in PWA and you could use them!

> Hi Emillio, I guess you are using the Adalo Marketplace QR Scanner right? If this is not Native and if this is PWA then that component doesn’t works. But the Pragmaflow QR Scanner and the Knight’s QR Scaner works on PWA! Pragmaflow QR Scanner : Knight’s QR Scanner : Thank you

Thank you
