RFID, or Radio Frequency Identification, is a technology that uses electromagnetic fields to automatically identify and track tags attached to objects. These tags contain electronically stored information that can be read from a distance by RFID readers.
Automatic Updates: Automates inventory counts and updates, minimizing manual intervention and human error.
Improving Efficiency
Speed: Speeds up the process of inventory tracking and management.
Automation: Automates various inventory management tasks, freeing up human resources for other activities.
Increasing Visibility
Tracking: Enables precise tracking of items throughout the supply chain.
Transparency: Enhances transparency and accountability in inventory processes.
How RFID Works in Inventory Management
RFID technology operates through a combination of tags, readers, and software to collect and process data. Here’s a step-by-step overview of how it works:
Step 1: Tagging
Attachment: RFID tags are attached to inventory items or containers.
Encoding: Information about the item, such as SKU, serial number, and other relevant data, is encoded onto the RFID tag.
Step 2: Reading
Scanning: RFID readers emit radio waves to scan RFID tags within their range.
Data Capture: The reader captures the information stored on the tags and sends it to the middleware for processing.
Step 3: Data Processing
Middleware: Processes the captured data and integrates it with inventory management systems.
Real-Time Updates: Updates inventory records in real-time, reflecting the latest status of each item.
Step 4: Monitoring and Analysis
Tracking: Continuously tracks the movement and status of inventory items.
Analysis: Analyzes inventory data to generate insights and support decision-making.
