How do we scan a 2D Data Matrix?

Tagged With:-

Hi All,

I'm Arun. We've received work for scanning 1-D, 2-D barcodes. I have understood how to scan a linear barcode, Firstly we divide the entire height into 10 equal intervals and send the light at different heights and get the overall grade. Please correct me if I'm wrong.

Also please help me to understand the scanning procedure for 2D Data Matrix, how is it graded?

Thanks In Advance.

Ben	Best Answer This information is not made available. You could try researching handheld scanner engines to learn about how scanners work. Posted 8.7 year(s) ago (0) (0) Report Abuse

Hi Ben,

Sorry Ben. I have put the question wrong.

I meant how do we verify the 2D Barcode (DataMatrix) using a scanner?

Attached is the image which tells how to do it for Linear Barcode. Can you please explain how the same is done for a 2D Barcode?

Thanks in Advance.

Ben	All 2D barcodes scan the same way; it can also depend on the scanner. If you are referring to how the scanner interprets the modules, this information is not provided. Posted 8.7 year(s) ago (0) (0) Report Abuse

Hi Ben,

Thank you for the answer. I'm looking specifically at the procedure in how Data Matrix (2D barcode0 is scanned.

Thanks in advance.

A 2D laser scanner such as the SC7USB2D scanner scans 2D barcodes with a point and click. This is how most 2D scanners work.

Here is a video example of the SC7USB2D scanning a QR Code barcode:

We do not have information about the scanning procedure and grading; most handheld scanners are not verifiers. However, we do have a PQA assessment for our 2D scanner.
