YJ-ES220 integrates two core functionalities—high-performance barcode scanning and advanced digital image acquisition—

delivering consistent, high-speed reading of barcodes regardless of quality. From standard printed codes to QR codes displayed

on mobile devices, every barcode is captured with exceptional precision. Engineered with professional anti-glare and backlight-

resistant technologies, the device excels at rapid barcode decoding even under extreme outdoor lighting conditions like direct

sunlight or backlighting. The innovative wide-voltage design flexibly accommodates different power supply scenarios, addressing

the varied electrical requirements of various terminal devices.

Advantages of Embedded Barcode Scanners

1.Decoding Technology: Employs independently developed core decoding algorithms combined with sophisticated image

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

wrinkled, and low-contrast variants, ensuring stable recognition performance in complex use cases.

2.Technical Support: Supports secondary development comprehensively, providing a complete SDK package compatible

with multiple operating systems to facilitate customized integration.

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

industrial control, terminal equipment, and security systems, enabling seamless integration with a wide range of hardware platforms.

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

5.Decoding & Scanning Capability: Universally compatible with 1D/2D barcodes on paper-based media (e.g., courier labels,

product packaging) and digital screens (e.g., mobile payment codes, electronic certificates), meeting scanning demands

across diverse industries.

6.Recognition Resolution: Features a 300,000-pixel high-definition image sensor that accurately captures fine-grained

barcode details, ensuring reliable 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 numbering systems, self-service ticketing machines,

and POS payment terminals in the retail and catering sectors.
