Choosing a barcode verifier

What are barcode verifiers? A barcode verifier is a piece of equipment used primarily by businesses that print and use barcodes.  Companies at all stages in the supply chain for a product may want to test barcode quality.

The need to test and grade the quality of a barcode arises from the necessity to ensure that any reader in the supply chain can interpret the barcode with a low margin of error. This is important in the industry as retailers often apply large penalties for non-compliant barcodes - understandably, given that products with an erroneous barcode cannot be scanned or processed by the retailer.  Customers cannot easily pay for and check out the goods, stock systems cannot be updated - the products with defective barcodes are effectively useless to them.

A barcode verifier works very much like a reader, but rather than simply decoding the barcode, a verifier performs a number of tests - eight in total. For each test, a grade is awarded which ranges from 0.0 to 4.0 (F to A). The lowest of the 8 grades is the scan grade. In most cases, a 2.5 (C) is the minimum acceptable grade.

Contrasting the barcode verifier again with a barcode reader, the verifier measures a barcode - and there is a requirement for the measurement to be repeatable and consistent. To achieve this, constant conditions - like sensor angle, distance, verifier aperture and illumination angle - are essential. A barcode reader, on the other hand, must interpret a barcode as reliably as possible in a wide range of conditions.

Standards for your Barcode Verifier

Barcode verifiers need to comply with ISO/IEC 15426-1 (linear) or ISO/IEC 15426-2 (2D) standards. 

This standard serves to define the measuring accuracy of a bar code verifier.
