I. Self-service, Say Goodbye to Queues: The Ultimate Smooth Shopping Experience

The core mission of self-service checkout machines is to completely eliminate checkout queues. Customers use the device's built-in high-sensitivity scanner to scan product barcodes, and then quickly complete payment via mobile payment methods such as mobile phone scanning, facial recognition, or NFC. The entire process requires no employee intervention, reducing the average checkout time to less than one minute. This is especially suitable for customers buying small quantities of items and prioritizing efficiency, significantly improving shopping smoothness and satisfaction.


II. Smart Hardware Integration: High-Definition Touchscreen, High-Speed ​​Printing, and Stable Connection

The device integrates the core hardware required for retail POS systems:


High-Definition Large-Size Touchscreen: Provides clear and intuitive operation guidance and information confirmation interface.


High-Sensitivity Scanner: Quickly and accurately recognizes 1D/2D barcodes.


Thermal Receipt Printer: Automatically prints a receipt after successful payment.


Wireless Antenna: Ensures stable Wi-Fi/4G network connectivity and supports real-time data synchronization and updates.


III. Advertising Carousel: Transforming Idle Screens into Marketing Platforms

The device features an intelligent advertising carousel mode. In standby mode or during checkout intervals, the screen automatically loops preset advertising images or videos, covering content such as:


Store Promotions


New Product Recommendations and Brand Promotions


Member Discount Information


Public Welfare or Friendly Reminders


This function transforms previously idle terminals into 24/7 online digital billboards, continuously enhancing store marketing exposure and promotional effectiveness, and improving space efficiency without incurring additional costs.

Significantly reduce operating costs: Reduce reliance on cashiers and optimize manpower structure.


Improve operational efficiency: Achieve 24/7 unmanned checkout capability and extend effective service time.
