High-Speed Embedded QR Reader for Automated Systems
Small Form Factor: Designed to be extremely compact to fit within the constraints of host equipment like kiosks,
vending machines, or industrial robots.
Board-Level Components: Often comes as a modular engine or board-level product (e.g., SFK, SE-K, or SE-SL
form factors), allowing OEMs (Original Equipment Manufacturers) to design it directly into their PCBs.
2. High-Performance Scanning
Advanced Imaging Technology: Utilizes a high-resolution CMOS image sensor to capture barcodes as a digital
image, enabling it to read both 1D (linear) and 2D (QR, Data Matrix, etc.) codes with high accuracy.
Motion Tolerance: Features a high frame rate that allows it to read barcodes on fast-moving objects, essential for
conveyor belt systems in logistics and manufacturing.
Omni-Directional Reading: Can decode barcodes presented at various angles, providing a "presentation" style of
scanning where users don't have to perfectly align the code.
3. Superior Illumination and Optics
Integrated Illumination: Includes built-in LEDs (often infrared or red) to provide consistent lighting for reliable scanning
in various ambient light conditions.
Wide Field of View: The optics are designed to have a specific field of view (near and far focus) to capture barcodes at
varying distances.
Application Scenario of Embedded Code Scanner
1. Retail & Self-Service
Self-Checkout Kiosks: Allow customers to scan item barcodes independently, reducing wait times and improving the
shopping experience.
Vending Machines: Used to scan QR codes for promotions or, in smart vending machines, to read a customer's mobile
payment code.
Smart Lockers: Scan barcodes on parcels for depositing items. Users retrieve their items by scanning a pickup code or
QR code from their phone.
Interactive Kiosks: In malls, museums, or airports, users can scan QR codes on tickets, membership cards, or brochures
to access information or redeem offers.
2. Logistics & Warehousing
Automated Sortation Systems: Embedded scanners are mounted above or alongside conveyor belts to automatically read
package barcodes at high speeds, directing them to the correct destination. This is a core component of modern distribution
centers.
Handheld Terminals & Inventory Vehicles: The scanning engine inside these mobile devices is embedded, enabling
workers to perform fast and accurate receiving, picking, and stock counting.
Smart Shelving & Robotic Picking: Integrated into shelving units or autonomous mobile robots (AMRs) to ensure accurate
identification and location of items for automated "goods-to-person" order fulfillment.
3. Industrial Manufacturing
Production Line Tracking: Installed along assembly lines to read barcodes (including Direct Part Marking - DPM) on
components. This allows for full traceability, recording production data, and quality control.
Robotic Guidance: Integrated into the arms of industrial robots to guide them in precisely picking up or assembling marked
parts.
