There are two main reasons why a barcode would have a reading error and that is either due to a poor image quality or because of flawed data quality.

Barcode Reading Errors

Poor image quality is a barcode failure that is easier to detect, since many of these problems can be identified visually or with low magnification. Barcode failure due to flawed data quality usually cannot be detected visually, but barcode verifiers are able to test for data structures, and when properly configured, can signal data problems quickly and easily.

Verification examines optical characteristics of the barcode compared to industry and international standards. The barcode is then given a pass or fail grade based on these parameters. Diagnostic information lets the operator know what defects may exist in the barcode, which can help to correct the printing process. Barcode verification is required for many industries and will ensure 100% scanability.

Barcode verification standards are set by international organisations (such as ISO) and industry groups (such as GS1 or HIBCC).

Limitations of Barcode Scanners

A common misconception is that a barcode scanner can be used to verify, but unfortunately this is not the case. A scanner is designed just to read the barcode, and just because the barcode can be read by your scanner this does not ensure that it can be read by all scanners. It only means that one area of the barcode can be read by that particular device.

Verifiers on the other hand can determine the quality of a barcode using various parameters such as; decoding, measuring and checking the format of the code. And as a barcode is measured through industry standards and not just from one scanner, they can analyze how well the barcode will perform in different environments. It will indicate where the barcode is defective so corrective action can take place.

Barcode Verifier Solution

Implementing a barcode verifier can go a long way to streamlining the quality control and manufacturing process. A barcode not scanning correctly can have serious effects ranging from manufacturing errors to production downtime. Verification gives you feedback about your barcode productions process that can be used to control the process itself. A successful verification result ensures that a labels or direct part marker is working properly and will be readable further in the supply chain.

Many retailers and also government agencies require barcodes to conform to industry standards. The only way to demonstrate barcode quality is through verification.

Verification guarantees a first time scan rate. Correctly scanning barcodes will prevent fines from major retailers or productions downtime. When barcodes do not scan correctly, the data has to be manually entered, opening it up to human error. Using a verifier would guarantee that this wouldn’t happen and that in turn would remove improve customer satisfaction.

The Cost Benefits

Barcode verification can save your company money by preventing chargeback’s. Major retailers, such as Tesco, are known for issuing costly chargeback’s when items delivered do not meet expectations. They fine £40,000 per incident and return the merchandise back at the manufacturer expense. Barcode verification will insure that merchandise will not be sent back because of unreadable barcode symbols.

If you are responsible for delivering readable, in-spec barcodes, then the only way to ensure that the barcodes function properly is with barcode verification.
