What are Barcodes?

The technology of bar coding is based on the recognition of dark and light elements of defined dimensions according to the rules defining the transition of characters into such patterns, known as the symbology specification.

The bar code symbol, as a machine-readable data carrier, must be produced in such a way as to be reliably decoded at the point of use, if it is to fulfil its basic objectives. Standard methodologies have been developed for measuring and assessing the quality of the symbols for the process control and quality assurance purposes during symbol production as well as afterwards. This standard is ISO/IEC 15416.

What is Barcode Verification?

A barcode verification system checks the bar code print quality. This process must use a reading devise and software that is manufactured under ISO/IEC 15426-1, bar code conformance specifications.

Barcode Verifiers V Barcode Scanners

Normal everyday barcode input devices, such as laser, wand and CCD scanners are not manufactured to the ISO/IEC 15426-1 standard and therefore cannot be used as verification equipment. They will only read, or not read, the bar code. They will not analyze the barcode and tell you what defects, if any exist in the code. Furthermore, because scanners are not calibrated on a regular basis like verifiers, one scanner may read a barcode and another may not. If you want to verify, you must have a verifier.

What are the key benefits of a Barcode Verification System?

A properly implemented barcode verification system provides cost saving benefits:

• Efficiency – Save time by eliminating the need to reprint barcodes
• Accuracy – Scan every barcode, every time without errors of manual data entry
• Compliance – Ensure your barcodes meet the requirements of your customer

What should you address when making a barcode verification system?

When putting together an effective and suitable barcode verification system there are a few key questions to answer:

1. What type of code do you need to verify? 1D or 2D?

2. Are you verifying codes for internal use or contract compliance?

3. How many barcodes will you need to verify daily?

4. Do you need a handheld or online verifier?

5. What printer are you using?

6. Will you need traditional or ISO/ANSI verification? Industry specific?

What are the components of a Barcode Verification System?

All barcode verification systems consist of one of these two components:

1. Handheld verifier – These verifiers are mobile devices that have a built in scanner and small display that provides a grading of each barcode. These allow you to spot check barcodes after they are printed and offer printed or downloadable reports on the verified codes.

2. Online verifier – An online verifier mounts on front of and connects directly to your printer to check each barcode as it is made. These devices allow you to automatically reprint poorly made barcodes at the printer level or even stop printing if continued poor quality codes are being made. These are best suited for high volume print applications where spot checking is not feasible.
