Thats sometimes the hard part. I started to search Barcode API - but I think that was the wrong approach. It was a bunch of stuff they wanted to sell me to plug into code.
I think the key here - it's stuff you can "embed" into your web site - anything that's as simple as that (like a YouTube video) can work - also - you need a little human readable text in the embde code - i put in some bogus text to make sure when I looked @ their embed code it was something I could pass a pareter into. ("NUMBER") - Simple as that.
