What Can You Do With a Handheld RFID Reader?
Cycle Counting
Walk through a stockroom or warehouse and capture compatible RFID tags without individually aligning every item with a barcode scanner.
Item Finding
Use RFID data to help locate tagged products, assets or equipment within an operational area.
Inventory Management
Capture RFID-tagged inventory during stock checks, replenishment and other inventory processes.
Asset Tracking
Identify tagged tools, IT equipment, reusable assets, machinery or other business equipment.
Goods Receiving
Use handheld RFID as part of workflows for verifying tagged products or assets entering a facility.
Retail Stock Control
Support stock counts, back-of-store management, item finding and inventory visibility in RFID-enabled retail environments.
Why Use RFID Instead of Scanning Every Barcode?
A conventional barcode scanner normally requires the operator to locate and present each barcode to the scanner.
UHF RFID works differently. Compatible RFID tags can be detected using radio-frequency technology without requiring the same direct visual alignment.
Barcode Scanning
- Individual barcode normally needs to be visible
- Very widely used
- Low-cost identification technology
- Excellent for individual transactions
- Simple and established workflows
UHF RFID
- No equivalent line-of-sight requirement
- Multiple compatible tags can be detected rapidly
- Useful for stock counts and asset searches
- Requires RFID tags and compatible software
- Performance depends on tags and environment
Many businesses use both barcode and RFID. RFID does not have to replace every barcode workflow.

RFD40/RFD90 or a Fixed RFID Reader?
Choose a Handheld RFID Reader
Use an RFD40 or RFD90 when the employee moves to the tagged items.
Examples:
- Stock counts
- Asset searches
- Retail inventory
- Warehouse audits
- Equipment checks
Choose Fixed RFID
Consider fixed RFID infrastructure when the tagged items move through a known read point.
Examples:
- Dock doors
- Warehouse portals
- Production checkpoints
- Conveyor areas
- Controlled entrances or exits
Some RFID deployments use both handheld and fixed readers.
Check Your Mobile Computer Compatibility
RFD40 and RFD90 sleds can form part of a combined Zebra mobile-computing and RFID solution, but compatibility depends on the exact reader, connection method, adaptor and host device.
Zebra's eConnex system supports compatible Zebra mobile computers, while selected models also provide USB and/or wireless connectivity.
Don't order the sled from the family name alone. Check the complete reader MPN, the mobile computer being used, required adaptor, charging arrangement and connectivity before purchasing.
