Barcode verification

Barcode verification is a test performed on your product sample. The test ensures the correctness of the number and the physical attributes of the barcode - size, height, location, reflective properties, etc. The test assesses the correctness and integrity of the encoded number and data as well as the scanning performance of the barcode symbol.


Barcode verification is best performed on an example of a completed product.
