YJ-ES220 is built with dual-core performance—robust barcode scanning and high-precision digital image acquisition—

delivering stable, high-speed reading of barcodes of all quality levels. From standard printed barcodes to QR codes

displayed on mobile screens, every code is captured with exceptional accuracy. Leveraging specialized anti-glare and

backlight compensation technologies, the device maintains fast barcode decoding even in harsh outdoor lighting conditions

such as direct sunlight or backlighting. Its innovative wide-voltage design flexibly adapts to different power supply scenarios,

addressing the varied electrical requirements of various terminal devices.

Advantages of Embedded Barcode Scanners

1.Decoding Technology: Utilizes independently developed core decoding algorithms fused with advanced image

preprocessing and real-time error-correction mechanisms. This enables efficient reading of barcodes in diverse

conditions, including faded labels, crumpled receipts, and low-contrast codes, ensuring reliable recognition in complex

operational settings.

2.Technical Support: Offers comprehensive secondary development capabilities with a feature-rich SDK package

compatible with multiple operating systems, allowing developers to customize and integrate the device seamlessly.

3.Rich Interfaces: Provides USB, TTL, RS232, RS485, and Wiegand interfaces, covering connectivity needs for industrial

control systems, terminal equipment, and security applications, enabling seamless integration with diverse hardware platforms.

4.Acquisition Speed: Boasts an ultra-fast acquisition speed of 1/60 second, ensuring instant barcode capture and decoding

without delay.

5.Decoding & Scanning Capability: Universally compatible with 1D/2D barcodes on physical media (e.g., shipping labels,

product packaging) and digital displays (e.g., mobile payment QR codes, electronic invoices), meeting the scanning requirements

of numerous industries.

6.Recognition Resolution: Incorporates a 300,000-pixel HD image sensor that accurately captures minute barcode details,

ensuring precise identification of small-format and high-density barcodes.

Application Scenarios for Embedded Barcode Scanners

Deeply integrated into various terminal devices within the IoT industry chain, it is suitable for self-service vending machines,

self-service inquiry terminals, intelligent logistics express lockers, queue number calling systems, self-service ticketing machines,

and POS payment terminals in retail and catering sectors.
