Impinj Speedway Revolution R420 | UHF RFID Reader - 4 Port

Impinj Speedway Revolution R420 UHF RFID Reader (4-Port) is a high-performance fixed RFID reader designed for real-time inventory tracking, asset management, and large-scale RFID deployments in retail, warehouse, and industrial environments.

Best for:
Retail inventory visibility, warehouse management, supply chain tracking, and RFID systems requiring multiple antennas and wide coverage.

Compatible with:
UHF RFID antennas, EPC Gen2 RFID tags, and RFID software platforms for inventory and asset tracking systems.

Note:
RFID reader only — requires antennas, RFID tags, and software for full system deployment. Not a barcode scanner or traditional POS device.

• 4 antenna ports for multi-zone and large-area RFID coverage
• High read performance using Impinj Autopilot for automatic RF optimization
• Reliable 24/7 operation for enterprise and industrial environments
• Scalable deployment for retail, warehouse, and logistics applications
• Flexible system design with support for multiple antennas and configurations

The Impinj Speedway R420 is one of the most widely deployed fixed RFID readers, offering proven performance for businesses implementing RFID-based inventory and asset tracking systems. With four antenna ports, it supports larger coverage areas and more complex deployments than entry-level RFID readers.

• Ideal for warehouse and distribution center tracking
• Used in retail for real-time inventory accuracy and shrink reduction
• Supports multi-zone RFID deployments
• Designed for high-volume, high-visibility environments

How it compares:

• Compared to R220 → more antenna ports (4 vs 2) for larger deployments
• Compared to handheld RFID readers → fixed infrastructure vs mobile scanning
• Compared to barcode systems → enables bulk, non-line-of-sight scanning

Where it fits:
Retail stores, warehouses, distribution centers, and industrial environments implementing RFID tracking systems.

Build your RFID system:

• Add RFID antennas for coverage and read range
• Add RFID tags for inventory and asset tracking
• Compare RFID readers to explore other configurations
