A New Ultra-Compact Scanner for Tiny Spaces

DENSO WAVE’s Smallest and Lightest Scanner Ever

The QM30 series is equipped with the newest module developed in-house by DENSO WAVE. The new module makes it possible to reduce the scanning lens surface area and shrinks the unit’s volume to about 1/4* that of the previous product.

Compact Dimensions Ideal for Incorporation into Various Devices

At just 3.5 cm wide, the unit is ideal for incorporating into devices that couldn’t otherwise accommodate a scanner. The QM30 helps design smaller scanner modules for space-saving installations.

Supports New High-security QR Code

The QM30 supports SQRC with its enhanced security features and can be used for authenticity verification of high-security member ID cards and similar applications. The Q M 30 al so scans QR co des displ ayed on smartphones for payment purposes.

Scanning range and field of view


  1. Scanner specifications are values obtained under an ambient light intensity of 500 lx or lower.
  2. Depending on light source position, angle to the label surface, and other factors, specular reflections may prevent scanning in certain cases.
  3. Close-distance scanning may be restricted in certain cases, depending on scanning field of view.
