Android PDA Embedded 2D Scanner with NFC Fast Barcode Decoding + Contactless Data Transfer

YJ-ES220N delivers outstanding barcode scanning performance and superior digital image acquisition capabilities, enabling

stable, high-speed reading of barcodes across a wide quality range—from common printed barcodes to QR codes displayed

on the screens of mobile phones, tablets, and other portable devices. Furthermore, it comes with built-in NFC fast card-swiping

functionality, making it a versatile solution for seamless data collection and contactless interaction in diverse IoT applications.

Advantages of Embedded Barcode Scanners

1.Decoding Technology: Employs independently researched and developed core decoding technology, which features

advanced image processing and pattern recognition algorithms to achieve fast and accurate reading of barcodes of different

qualities, including those with low resolution or printing defects.

2.Technical Support: Supports secondary development with a comprehensive SDK development kit that offers extensive API

documentation and sample codes, ensuring compatibility with multiple operating systems and simplifying the integration

process for developers.

3.Rich Interfaces: Features a complete set of interface options—USB, TTL, RS232, RS485, Wiegand interfaces, and NFC

protocol—providing flexible connectivity solutions for various terminal devices, from consumer electronics to industrial control systems.

4.Acquisition Method: Adopts an image-based acquisition approach that captures 2D visual data of barcodes, allowing for

more robust recognition compared to traditional laser scanning, especially for distorted or irregularly shaped codes.

5.Decoding and Scanning Capability: Can efficiently recognize 1D and 2D barcodes printed on paper and displayed on digital

screens; the integrated NFC module supports fast card-swiping operations, enabling applications such as access control, loyalty

program management, and contactless payments.

6.Recognition Resolution: With a 300,000-pixel recognition resolution, the device ensures that even small or dense barcodes are

captured clearly, supporting reliable data extraction in high-volume transaction environments.

Application Scenarios for Embedded Barcode Scanners

Primarily used for integration into various terminal devices in the IoT industry chain, such as self-service vending machines

in shopping malls and offices, self-service inquiry terminals in banks and hospitals, intelligent logistics express cabinets in

residential areas, queue number calling systems in government service centers, self-service ticket machines at cinemas and

stadiums, and POS payment devices in supermarkets and convenience stores.
