I am looking for a ready made package for my web application with the following criteria:
1- Complete support for all versions of IOS, Android and laptops.
2- Ability to zoom in and zoom out.
3- Support for rear camera if there are multiple cameras in the back. I want it to be like the native camera app.
4- Ability to support Ajax requests after reading the QR Code.
I don't need someone to develop something from scratch, I think there are a lot of open sources libraries, so you can select on of them after validating all the previews criteria.
