Hi - I’ve never done this before!
But… one suggestion would be to use an LLM which is Vision capable such as GPT-4o-mini or Gemini 1.5/2.0 Flash. Via REST API, you could send the image and ask it to extract the information you require from the tag as a JSON response.
You don’t mention whether you require to extract the SKU from the barcode, but presumably you would need to do that also, there are various libraries available to read barcodes, so you could use one of these. There is also a Retool barcode scanner here: New: Scanner V2
Also:
Free: zxing-js
Paid: strich
If you need help with any of this, I am a software contractor and could potentially work on it for you.
Good luck!
