RFID in Retail

How RFID Works

RFID helps you track every item in your store. It uses radio waves to read tags on products. These tags have important information about each item. You put a tag on every product for item-level tagging. RFID readers send signals to the tags and get the data. Antennas help find tags even if you cannot see them. The system sends all the data to special software. This software sorts the data and shows your inventory clearly.

Component/Process	Description
RFID Tags	Small devices that store electronically encoded information attached to items or assets.
RFID Readers	Devices that emit radio signals to detect and read data from RFID tags.
Antennas	Enhance the detection capabilities of RFID readers.
Software Platform	Collects, processes, and organizes data from RFID systems to create actionable insights.

RFID Benefits for Inventory Accuracy

RFID lets you see your products in real time. You always know where items are and how they move. This helps you stop running out or having too much stock. Inventory counts are much faster with RFID. You can finish counting in less time, up to 75% faster. Your workers can help customers more instead of counting. RFID makes your inventory records more accurate. Stores using RFID see accuracy go from less than 70% to over 95%. Item-level tagging helps you find missing items and keep records right. Customers get better service because you know what is in stock.

Benefit	Description
Real-Time Visibility	RFID provides full visibility into inventory levels, locations, and movement.
