Barcode Readers Vs. Verifiers

Barcode readers vs. verifiers reading datamatrix vs. grading datamatrix

The verification process differs from barcode reading in several important ways

While barcode readers are designed to read codes, a barcode verifier ensures that codes are marked correctly and meet an industry’s—rather than an individual producer’s—quality threshold. Compared to barcode readers, barcode verifiers are a superior measure of symbol readability because they normalize the range of performance among various types of readers, from camera and laser to handheld and fixed-mount.

While a barcode reader is designed specifically to read codes, a barcode verifier:

  • Ensures data is formatted correctly
  • Confirms barcodes can be read by all scanners
  • Pinpoints the reason(s) why a barcode will not scan
  • Prints reports listing barcode grades to certify they meet industry standards

Analyzes Industry Standard Parameters

A verifier takes more time to analyze a code and generates more data than a reader, which only reveals the data within a code. Verifiers analyze and report on formal parameters based on international standards. These parameters measure a number of factors that affect barcode readers’ abilities to identify and decode a code. Verifiers test different parameters for 1-D, 2-D, and direct part mark (DPM) codes based on a governing standard, such as an ISO international standard.

Identifies Printing and Marking Problems

Unlike barcode readers, verifiers also pinpoint the reason(s) why a barcode will not scan, revealing where the barcode is deficient so the producer can take corrective action. Printed reports listing barcode grades help certify that codes meet industry standards.
