The Zebra RFD40 Series is a high-performance handheld UHF RFID sled designed to transform compatible mobile computers into powerful RFID inventory capture tools. Offering high tag read rates, broad range coverage, and options for integrated 2D barcode imagers and extended range antennas, this modular sled communicates via secure direct eConnex connections or Bluetooth wireless. It is widely used in retail item-level inventory cycle counting, loss prevention, warehouse asset tracking, healthcare equipment audits, and supply chain cross-docking. By reading hundreds of tags per second without requiring direct line of sight, the RFD40 Series slashes inventory audit times from hours to minutes and dramatically elevates inventory accuracy.
