How does an RFID Solution works
- Tagging: Each item, asset, or product intended for tracking is affixed with an RFID tag. This tag consists of a microchip that stores a unique identifier and other relevant data, and an antenna to transmit and receive radio signals.
- Reading: RFID readers, strategically placed at key points (e.g., doorways, production lines, warehouse aisles), emit radio waves. When an RFID tag enters the reader’s range, it receives energy from these waves (for passive tags) or uses its own power source (for active tags) to activate and transmit its stored data back to the reader.
- Data Transmission: The RFID reader captures the data from the tags and converts it into a digital format. This data is then typically sent via network connections (wired or wireless) to a central middleware or software application, like a RFID Solution.
- Data Processing & Integration: Middleware acts as a bridge, filtering and aggregating the raw RFID data before sending it to the core business systems, such as an Enterprise Resource Planning (ERP) system or a Warehouse Management System (WMS). This ensures only relevant, clean data is passed on, preventing data overload.
- Action & Analysis: The integrated software then processes this real-time data. For example, it can automatically update inventory levels, track asset movements, trigger alerts for low stock, or provide detailed reports for analysis. This enables automated decision-making and provides valuable insights into operations.
