RFID (Radio Frequency Identification)

RFID (Radio-Frequency Identification) is a wireless technology that uses radio waves to automatically identify, track, and capture data from tagged items as they move through the supply chain. 

Unlike barcodes, RFID tags do not require line-of-sight scanning, meaning multiple items can be read simultaneously, even when inside cartons, on pallets, or moving rapidly through a facility.

In logistics and warehouse operations, RFID enables real-time visibility, improved inventory accuracy, automated data collection, and enhanced productivity across every stage of the fulfillment process.

How RFID Works

RFID systems consist of three primary components:

• RFID Tag
  A small tag containing a microchip and antenna. It stores data such as product IDs, SKU numbers, batch or lot details, expiration dates, and more.
  
• RFID Reader
  A device that emits radio signals to activate nearby RFID tags and capture their stored information. Readers can be fixed at doorways, mounted on forklifts, or handheld.
  
• RFID Software System
  The data collected by readers is sent to a warehouse management system (WMS) or inventory platform, creating real-time visibility into inventory movement and status.

When a tagged item passes an RFID reader, the system automatically records the event—no manual scanning, direct contact, or visual alignment required.

Types of RFID Tags

Tag Type	Description	Best Use Cases
Passive RFID Tags	No internal battery; activated by a reader’s signal	Inventory tracking, retail, warehouse scanning
Active RFID Tags	Battery-powered; longer read range	Asset tracking, yard management, vehicle or equipment tracking
Semi-Passive (BAP)	Battery-powered but still reader-activated	Cold chain monitoring, environmental data logging

Key Uses of RFID in Logistics

Real-Time Inventory Visibility

RFID provides instant insight into inventory location and movement from receiving docks to storage aisles to outbound staging areas.

Automated Data Capture

Multiple items are scanned at once, enabling faster receiving, picking, and shipping with minimal human intervention.

Improved Accuracy

RFID significantly reduces miscounts and increases inventory accuracy, often to 99% or higher, helping prevent stockouts, overshipments, and shrinkage.

Streamlined Warehouse Operations

RFID accelerates high-volume processes such as cycle counting, replenishment, cross-docking, and consolidation.

Security and Loss Prevention

Systems can trigger alerts if tagged items move into unauthorized areas or leave a facility unexpectedly.

Reusable Asset Management

RFID tags track the movement and usage of pallets, bins, kegs, roll cages, and returnable containers, which improves asset utilization and reduces loss.

Environmental Monitoring

Specialized RFID tags equipped with sensors can record temperature, humidity, or shock, supporting compliance for pharmaceutical, food, and chemical logistics.

Example Applications of RFID in Warehousing

• Receiving – Automated inbound scanning identifies pallet and case contents instantly.
  
• Picking & Packing – Readers confirm correct SKU selection without manual barcode scanning.
  
• Cycle Counting – Staff can count thousands of units in seconds by walking through aisles with handheld readers.
  
• Dock Door Monitoring – Fixed readers verify outbound loads, reducing shipping errors.
  
• High-Value Asset Tracking – Equipment, tools, or IT assets can be tagged for real-time location tracking.
  
• Cold Chain Compliance – Sensor-enabled tags ensure temperature-sensitive goods remain within required ranges.
  

RFID vs Barcode Scanning

RFID does not replace barcodes entirely—but it dramatically increases efficiency in high-volume warehouse environments.

RFID	Barcode
Does not require line-of-sight	Requires line-of-sight scanning
Multiple items scanned simultaneously	One item scanned at a time
Higher accuracy and automation	More manual labor and slower processes
More expensive to implement	Low-cost, simple technology
Can read through packaging/materials	Must have clear visual access

Benefits of RFID for Logistics Providers

• Increased productivity
• Reduced labor costs
• Higher accuracy in receiving, picking, and inventory
• Real-time visibility across multiple locations
• Better decision making through live data
• Enhanced customer satisfaction due to fewer errors and faster fulfillment
