About This Product

■ High -speed reading of mobile QR code
The QR code displayed on the LCD screen of the mobile phone can be read at high speed regardless of the backlight status (ON/dimming).

■ Expansion of reading fields
With the realization of wide-viewing fields, wide barcodes such as PDF417 and GS1-128 (EAN-128) have become easier to read.

■ Compatible with various code
Not only reading various barcodes printed on paper, 2D code, but also 2D cords such as SQRC and AZTEC code.

■ High -resolution code reading
The adoption of the mega pixel sensor has achieved a resolution of 0.25mm.

■ Read of SQRC (QR code with security function)
Since it supports SQRC, it is powerful for applications that do not want to leak information to third parties such as personal information and parts characteristic information.

Features
1: Locks code data
Only any scanner can have data that can be read

2: Mixing public data and private data
Public data that can be read with a general scanner and private data that can read only a specific scanner can be mixed in one code

3: It looks like a conventional QR code
The appearance is the same as a normal QR code. Therefore, it is difficult to understand the presence or absence of private information, and a higher security effect is obtained.
