Compact and lightweight design

The seamless integration of the camera and decoder board makes the scan engine extremely small and lightweight(max Dimensions:21.5(W)*9.0(D)*7.0(H)mm,Weight only 1.2g), easy to install in miniature devices,such as Bluetooth pocket barcode reader,PDA,Finger barcode scanner,tablet barcode reader.

Multiple Interfaces

Q1 barcode scanner module supports USB and TTL-232 transmission interfaces.

Outstanding power efficiency

The scanning engine is equipped with advanced and latest technologies that help reduce its power consumption and prolong its service life.

Rapid on-screen barcode capture

Specially tuned design for on-screen barcode, The Q1 barcode module excels at reading on-screen barcodes even when the screen is covered with protective film or set to its lowest brightness.

High Performance

Equiped with 640*480 CMOS image sensor , read 1D 2D QR codes on screen and paper ; Scans fast and accurately,the scan engine can quickly and effortlessly decode poor quality bar codes (e.g., low contrast, twisted, laminated, damaged, torn or creased bar codes).

Wide-range in Application 

It can be used in PDA, wireless scanning gun, industrial internet of things devices, self-service machines, Kiosk , Turnstile, Mobile Payment and other usage scenarios. 

Support second development

Provide SDK Serial command available for development. 

Support Decoding Long Barcode

The engine is especially good at decoding long barcodes at close range, and can easily decode all kinds of long barcodes.
