Why RFID Is Becoming a Preferred Choice in Inventory Management
RFID offers a modern approach that enhances efficiency, accuracy, and overall control of inventory. Its growing popularity is driven by its ability to automate and streamline processes that were once manual and prone to error.
Whether you are using active or passive RFID tags, the process of tracking inventory in a warehouse works like this:
- Tagging: Each item or pallet is fitted with an RFID tag, which contains a small radio transponder, receiver, and transmitter.
- Reading: An RFID reader in the warehouse emits an electromagnetic pulse. When an RFID tag comes within the range of this pulse, it activates.
- Responding: Once activated, the RFID tag sends back digital information to the reader, including a unique inventory number.
- Identifying: The RFID tag’s memory holds specific identifiers, allowing the system to read and recognize each tag individually.
- Tracking: The inventory number received from the RFID tag is used to monitor and manage the location and status of inventory items throughout the warehouse.
How RFID Functions in a Warehouse
The key distinction between active and passive RFID inventory systems lies in how the RFID tags are powered, but the overall workflow in a warehouse is similar for both types. Before a shipment arrives at the warehouse, each item or pallet is equipped with an RFID tag, which stores essential information about the contents. Upon arrival at the warehouse, RFID tags on the shipment send their data to readers strategically positioned throughout the receiving and storage areas to ensure optimal signal reception.
The readers transmit this information via electromagnetic waves and then relay it to a central warehouse management system. The system processes and can update this data, sending new information back to the RFID tags for future retrieval.
This setup allows warehouse operators to conduct real-time asset counts and manage advanced inventory transactions efficiently. Once the inventory arrives, the following processes occur:
- Scanning: RFID readers begin scanning each tagged item when the shipment arrives.
- Data Transmission: The scanned information is transmitted to the central warehouse management system.
- Data Update: This data is then updated and returned to the products’ RFID tags for future reference and recall.
Does RFID Enhance Inventory Accuracy?
Yes, RFID significantly enhances inventory accuracy. Unlike traditional barcode systems, which require line-of-sight and manual scanning, RFID tags can be read from a distance and through obstacles. This leads to fewer errors and more reliable data. RFID systems provide real-time updates, which helps maintain accurate stock levels and reduce discrepancies between recorded and actual inventory. This improved accuracy supports better decision-making and helps prevent stockouts or overstock situations.
