App serial number function added to existing app

hi, we have an existing app for colouring books, we need to have serial number recognition built into it. We would then put a serial number on each book, they input it into our app and the app is activated.

We already have the full app, just need to recognise, buy and host the serial numbers.

please say serial app to show you know

thanks
