Features
Excellent reading capability
The QS20H can read standard QR Code with approximately 2,000 characters (numeric), thus creating a wide range of applications using large portable data files. Additionally, the QS20H reads Micro QR Code, PDF417 and MaxiCode, as well as linear bar codes.

Enhanced reading abilities with triple LED pointer
The triple LED pointer shows the center and the range of the reading area. This allows you to read the target symbol easily. The QS20H has been designed to accommodate fluctuations in ambient light, which enables increased reading ability in any environment.

Capable of reading high density bar codes omni-directionally
Allows you to read various types of bar codes (UPC/EAN, Code 39, NW7, ITF, Code 128) in all directions. The QS20H can read high density bar codes with narrow 0.15mm bars to bars that are wider than the reading window.
