Arealer MJ-340 Embedded USB 1D/2D/QR Barcode Scanner Module
Arealer MJ-340 Embedded Barcode Scanner – Fast, Reliable 1D/2D/QR Code Reading Meet the Arealer MJ-340 Embedded Barcode Scanner Module — a compact, high-performance scanning soluti on built for self-service kiosks, gate machines, ticket checking systems, and mobile payment terminals. With self-induction (hands-free) scanning and blazing-fast 200 scans/second speed, this USB module delivers accurate reads every time, even on damaged or blurry codes. Why Choose the Arealer MJ-340? Versatile 1D & 2D Scanning: Reads virtually all major barcode formats including EAN-13, UPC-A, Code128, Code39, QR Code, PDF417, Data Matrix, and many more — all in one module. CMOS Image Technology: The 752×480 CMOS sensor scans both printed paper barcodes and on-screen codes with ease, overcoming partial damage or low contrast without missing a beat. Self-Induction (Auto-Trigger) Mode: Hands-free inductive reading automatically activates when a barcode is presented — perfect for high-traffic, self-service environments. Eye-Safe White LED: Soft white LED light source (0–100,000 LUX) with no harmful laser — safe for customers and staff during continuous operation. Rugged Solid Insulation Design: Engineered with solid insulation construction to protect the internal components from external interference and ensure user safety. Large Scan Window: The 46.5 × 31.5 mm scanning window easily captures larger barcodes in a single pass. Plug-and-Play USB Interface: USB 1.1 (HID-KBW / HID-POS) connectivity means no drivers needed — just plug in and start scanning on any Windows XP/Vista/7/8/10 system. Low Power Consumption: Runs at just 1.75W (DC 5V, 0.5A), making it energy-efficient for 24/7 deployments.

Frequently Asked Questions Q: What barcode types does the Arealer MJ-340 embedded scanner support? A: The MJ-340 supports a wide range of 1D barcodes (including EAN-13, UPC-A, Code128, Code39, ITF, GS1 Databar, and more) as well as 2D codes such as QR Code, PDF417, and Data Matrix — making it suitable for virtually any retail, ticketing, or payment application. Q: Is this barcode scanner module easy to install? A: Yes. The MJ-340 features a USB plug-and-play interface (HID-KBW / HID-POS), so no additional drivers are required. Simply connect it via USB to any Windows XP/Vista/7/8/10 computer or kiosk, and it's ready to scan immediately. Q: Can this scanner read barcodes from phone screens or damaged labels? A: Absolutely. The CMOS image scanning technology is designed to decode both printed paper barcodes and on-screen codes (e.g., on smartphone displays). The high-performance decoding chip also handles incomplete or blurry barcodes that traditional laser scanners often fail to read. Q: What environments is this embedded barcode scanner best suited for? A: The MJ-340 is purpose-built for embedded deployment in self-service kiosks, gate/turnstile machines, ticket checking systems, mobile payment terminals, and retail POS setups. Its self-induction (auto-trigger) mode makes it ideal for high-traffic, hands-free operations. {"@context": "https://schema.org", "@type": "FAQPage", "mainEntity": [{"@type": "Question", "name": "What barcode types does the Arealer MJ-340 embedded scanner support?", "acceptedAnswer": {"@type": "Answer", "text": "The MJ-340 supports a wide range of 1D barcodes (including EAN-13, UPC-A, Code128, Code39, ITF, GS1 Databar, and more) as well as 2D codes such as QR Code, PDF417, and Data Matrix — making it suitable for virtually any retail, ticketing, or payment application."}}, {"@type": "Question", "name": "Is this barcode scanner module easy to install?", "acceptedAnswer": {"@type": "Answer", "text": "Yes.
