The self-service cash register scanning engine is a scanning device used in self-service cash register systems. It can quickly and accurately read product barcodes or QR codes, and automatically complete price calculations and transaction processing.

Self-service cash register scanning engines usually use technologies such as high-definition cameras, image recognition algorithms, and laser scanners to achieve rapid and accurate identification of product barcodes or QR codes. When the customer places the product on the checkout counter, the scanning engine will automatically scan the barcode or QR code on the product and match the scan result with the product information to quickly calculate the product price and complete the transaction processing.

The self-service cash register scanning engine has the following features:

Efficiency: The scanning engine can quickly and accurately identify product barcodes or QR codes, shortening customer waiting time.

Convenience: Customers can operate the self-service cash register by themselves without the assistance of staff, which is convenient and fast.

Reliability: The code scanning engine uses advanced technology and high-quality hardware equipment to ensure the accuracy and stability of recognition.

Scalability: The self-service cash register scanning engine can cooperate with various payment methods to achieve diversified payment methods.

The internal structure of the self-service cash register scanning engine usually consists of the following parts:

Image Capture System: including high-definition cameras and lighting systems, used to capture images of product barcodes or QR codes.

Image Processing Chip: used to process the captured images, including decoding, analyzing, matching and other operations on the images to identify product information.

Central Processing Unit (CPU): It is the core component of the code scanning engine. It is responsible for processing various instructions and data and controlling the operation of the entire code scanning engine.

Memory (RAM): used to temporarily store data and programs during processing, and to quickly access various data and programs.

Memory (ROM): used to store the firmware (firmware) and other programs of the scanning engine.

Power Module: used to provide power, usually using switching power supply or other forms of regulated power supply.

Communication Interface: used to communicate with other modules of the self-service cash register, such as monitors, keyboards, printers, etc.

In addition, the scanning engine may also contain other auxiliary components, such as fans, radiators, etc., to maintain stable operation of the device.

It should be noted that the internal structure of the QR code scanning engine of different brands and models of self-service cash registers may be different, but they usually include the above main parts.
