Does the Intermec Scanner SG20T1D scan Qr code? or ARD? or only bar caodes

The Intermec SG20T1D scans only 1D barcodes. It does not scan QR codes or other 2D codes like ARD. For 2D code scanning, a 2D model of the SG20 is required.

    Long-term exposure to the laser framing beam can damage your vision. The SG20T contains either a 1D imager (SG20T1D), a 2D imager (SG20T2D or SG20T2DHC) or high performance 2D imager (SG20THP or SG20THC) to scan bar code data. The type of scan engine you are using and the type of bar code you are decoding determines the way you scan the bar code.
  • Page 23 Chapter 2 — Scanning with the SG20T If you are using bar code labels that are encoded in a different symbology, you need to enable the symbology on your SG20T. Use EasySet version 5.6.5.1 or later to enable and disable symbologies for your scanner.
