Software

Supports rMQR code scanning（except AT27Q-SB）

The new QR code 'rMQR Code', which enables printing in long, narrow spaces, can also be read. This expands the range of applications. (To read rMQR, update the firmware to the latest version.)

＊Please use a model that supports 2D codes.
＊AT27Q-SB does not support reading.

Scanning Performance

High-speed shutter and readability from any direction (360 degree)

You can improve your work efficiency by the high-speed shutter that enables operation not affected by camera shake, and readability from any direction.

Wide-angle scanning, improved readability

The number of horizontal pixels is increased and reading algorithms improved. Readability for wide barcodes used for public utility bills, medical bills, etc. is improved.

Improved resolution useful for various businesses

The newly developed reading engine enabled 0.125 mm resolution for 1D barcodes and 0.167 mm for 2D barcodes. The scanner can be used for a wide range of businesses such as operations of plants, hospitals and shops.

Multi-row barcodes can be read at one time.

The scanner can read two-row barcodes of books and up to three-row other barcodes. Decrease in the reading frequency can lead to drastic reduction in working hours.

Useful Functions

Possible to read barcodes on mobile phone LCD screen

The newly developed unique LED illumination control function is incorporated in the scanner to suppress specular reflection. The device can quickly read barcodes on mobile phone LCD screens.

Eye-friendly LED marker

In addition to the laser guide marker-type model, which is already on the market, the LED marker-type model that indicates the scanning area has been released. The scanner considers the safety of eyes, ideal for the use in service industries such as supermarkets.

Easy-to-use image capture function

The scanner can read not only barcodes but also take pictures. The device enables you to easily read even small characters. This function is useful particularly for logistics and transportation industries dealing with bills.(2)

1. With one reading pass over a 5s period.
2. One JPEG image can be transferred within one second in the case of USB connection.
