Woocommerce Warranty Advice?

I’m looking for suggestions for wordpress/woocommerce plugins or configurations that would help with a warranty processing website:

My client sells electronics to the government and would like me to design a website to help with processsing/upselling warranties and processing reworking for out-of-warranty items.

Each product sold has a unique serial number that indicates the week it was sold. Someone suggested a QR code could be put on a sticker that the customer could scan to find details about their product. It would let them know whether their item was still covered by warranty or not.

I have no idea how to execute that serial number functionality! I’ve made many other normal ecommerce sites though.

Maybe I don’t need woo for this, but it features a number of warranty plug-ins. I’m open to suggestions to do this in a more efficient way.

More detail:
? I have set up a wordpress/divi site for this.
? These serial numbers would ideally be able to be entered and searched, or embedded into the QR codes to be scanned which would tell the customer which products are still covered by warranty.
? Someone in the client’s shipping department would probably enter newly sold products into the website’s database and create the QR codes before shipping, unless there is a better way to do this. (Is there a QR plugin that would help with this?)
? My main area of concern is: how do I take these serial numbers and make them do anything useful? We’d have to connect them to something that would be able to decide if the individual serial number was in our out of warranty.

Thanks!!
