YJ-ES220 is equipped with dual-core capabilities—robust barcode scanning and high-performance digital image

acquisition—enabling stable, high-speed recognition of barcodes across all quality levels. From standard printed

barcodes to QR codes displayed on mobile device screens, it captures every code with precision. Leveraging professional

anti-glare and backlight optimization technologies, it can quickly decode barcodes even under extreme lighting conditions

such as direct outdoor sunlight or backlighting. The innovative wide-voltage design flexibly adapts to diverse power supply

scenarios, meeting the varied electrical needs of different terminal devices.

Advantages of Embedded Barcode Scanners

1.Decoding Technology: Adopts independently developed core decoding algorithms integrated with advanced image

preprocessing and fast error-correction mechanisms. It efficiently reads barcodes of all quality types, including faded,

wrinkled, and low-contrast ones, ensuring stable recognition in complex application scenarios.

2.Technical Support: Fully supports secondary development and provides a comprehensive SDK package compatible

with multiple operating systems, facilitating seamless customization and integration.

3.Rich Interfaces: Comes with USB, TTL, RS232, RS485, and Wiegand interfaces, covering connectivity requirements

across industrial control, terminal equipment, and security systems to achieve seamless docking with various hardware platforms.

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

5.Decoding & Scanning Capability: Universally compatible with 1D/2D barcodes on paper carriers (e.g., courier waybills,

product packaging) and digital screens (e.g., mobile payment codes, electronic documents), catering to scanning needs

across multiple industries.

6.Recognition Resolution: Equipped with a 300,000-pixel high-definition image sensor that accurately captures fine barcode

details, guaranteeing precise recognition of small-sized 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.
