How to read barcodes from PDFs and images?

Automate barcode scanning from documents with no-code workflows in 15 minutes!


Barcodes are everywhere. From books, clothes, and medicines to shipping containers, barcodes make it possible to store a lot of information in an array of white and black pixels.

Now, if you have a barcode, how do you extract information from the barcode?

If it is on paper or a physical product, it’s easy, you can use a laser-based barcode reader, or you can use a camera-based barcode scanning app. But what if you have a PDF with multiple barcodes or a scanned document with barcodes on multiple pages?

Well, there are two ways to go about it.

Either you can use an online barcode scanner, or you can use automated solutions to do so. We will take a look into how to read barcodes from PDFs and images using:

How to read barcodes from PDFs and images using document automation software?

Document automation software can automate document data extraction using advanced parsing rules-based workflows. You can use document automation software like Nanonets to extract data like:

  • Numeric data: dates, taxes, discounts, amounts, etc
  • Alphanumeric data: Passport number, ID, addresses
  • Selective text: email address,
  • Special text: QR codes, barcodes, signature

And more from various documents like contracts, insurance applications, identity documents, passports, legal documents, and more.
