Hello,
I hope you are doing well!
Thanks for sharing your requirement. I checked your requirement and understood that you want an Mobile app focused on QR & Barcode scanner.
I would like to tell you that I have a good amount of experience in the same(without any 3rd party library) and would love to help you with your requirement as well.
I got a basic understanding of the system, user can scan the bar code or qr code from mobile and and after successfully scanning the code user will get the information from bar code.
I have some queries and it would be great if you clear all my queries before moving to the next step.
It would be great if you could come over a Skype call where we discuss about the queries and discuss about your requirement in details.

Looking forward to hearing from you soon.
Stay Safe!
Thank You
