Barcodes are printed by various types of printers like Zebra printers and others. The barcodes printed are read by devices called barcode scanners or barcode readers. The main function of a scanner is to recognize the data encoded in a barcode. So it is necessary to have a better quality scanner which can read even lesser quality barcodes.
However, in order to increase the quality control and reduce contract compliance standards of barcodes, it is necessary to verify the printed barcodes. Barcode verifiers are the devices which are used to check the validity of barcodes. The process of barcode verification is risk management and includes high knowledge and experience. A barcode verifier decodes, measures, and grades the quality of the barcode symbol. Industry specification standards are checked by barcode verifiers. The barcodes are verified during or after the printing process. Any faulty barcodes created must be eliminated and reprinted again.
Barcode scanners and barcode verifiers are not the same. A barcode scanner only helps in assuring the scanning nature of a printed barcode by that particular scanner. But a barcode verifier ensures scannability of a barcode by any type of scanner.
The other difference between scanners and verifiers is the time where they are used. Barcode verifiers are used in between printing process and scanning process. But, barcode scanners are used for scanning in the final process.
Hence, it must be known that a barcode label printed by a Zebra printer is scanned by a barcode scanner and checked by a barcode verifier.
