Navigate to a website that offers a free check digit calculator such as, or These websites verify if a barcode is valid by matching its check digit, which is the last digit displayed on the barcode.

Can you test a barcode?

The only way to reliably predict barcode performance is to test it against a known and internationally accepted standard that defines the quality of its various characteristics—things like reflective differences between the bars and spaces and the reflective consistency of the symbol and its background.

What is barcode validation?

Barcode Validation is the process of confirming that the correct barcode information is being applied to the correct product, but not necessarily that the barcode meets a particular quality standard. A poorly printed barcode may pass a validation test but could fail on verification.

What is barcode confirmation?

Barcode verification is the process of grading barcodes. These standards enable interoperability between barcode printing and scanning systems, so that both industries and individuals can depend on symbols being printed and scanned successfully, regardless of where they were produced or handled.

How is a barcode scanner used?

A barcode scanner, also called a point-of-sale (POS) scanner or a price scanner, is a device used to capture and read information contained in a barcode. A barcode scanner works by directing a beam of light across the barcode and measuring the amount of light that is reflected back.

How are barcodes generated?

Do barcode scanners need calibrated?

No need for calibration. A barcode scanner operates digitally based on Binary signals (0, 1). What you might wish to do is validate the software if it developed in house or just mention the fact that it is commercially available (if bought in).
