Besides just scanning ISBN barcodes, CLZ Scanner can also “read” ISBN numbers that are printed on the book using our automatic built in Optical Character Recognition (OCR) system.

Reading ISBN numbers with OCR is super useful for:

  • Older books without barcodes, but with an ISBN printed on the cover or on the inside of the book.
  • Books where the barcode on the book is not an ISBN barcode but a UPC barcode. Those UPC barcodes usually have the ISBN number printed above the barcode which can be read!
