Embedded 2D Barcode Scanner with NFC Seamless Integration for Android PDA Devices

YJ-ES220N is engineered with robust barcode scanning proficiency and high-performance digital image acquisition

capabilities, enabling it to stably and swiftly decode barcodes of varying quality levels—ranging from standard printed

paper barcodes to dynamic QR codes displayed on smartphone and tablet screens. Additionally, it integrates seamless

NFC fast card-swiping functionality, catering to the diverse data collection demands of modern IoT applications.

Advantages of Embedded Barcode Scanners

1. Decoding Technology: Leverages independently developed core decoding algorithms, which deliver reliable and rapid

recognition of barcodes across different quality spectrums, ensuring minimal read failures even for low-contrast or damaged

codes.

2.Technical Support: Fully supports secondary development initiatives, offering a comprehensive SDK development kit that is

compatible with a wide array of mainstream operating systems, including Windows, Linux, and Android, to facilitate flexible integration.

3.Rich Interfaces: Comes equipped with an extensive set of interface options—USB, TTL, RS232, RS485, Wiegand interfaces,

and NFC protocol—covering the connectivity requirements of most industrial and consumer terminal devices.

4.Acquisition Method: Employs an advanced image-based acquisition approach, which captures detailed visual data to ensure

precise barcode recognition, outperforming traditional laser-based scanning in complex scenarios.

5.Decoding and Scanning Capability: Excels at recognizing both 1D and 2D barcodes printed on physical media and displayed

on digital screens; the integrated NFC module also enables quick and secure card-swiping operations for access control or

payment functions.

6.Recognition Resolution: Features a 300,000-pixel image sensor, providing sufficient clarity to capture fine barcode details

and ensure accurate data extraction in fast-paced operational environments.

Application Scenarios for Embedded Barcode Scanners

Designed for seamless integration into a broad range of terminal devices within the IoT industry chain, such as smart

vending machines, self-service information inquiry kiosks, intelligent logistics express lockers, queue management systems,

self-service ticketing terminals, and POS payment terminals for retail and catering sectors.
