About Impinj
Founded in 2000 and headquartered in Seattle, Washington, Impinj pioneered RAIN RFID technology, growing from a Caltech research lab into the global leader in wirelessly connecting items in the physical world to the AI-powered digital world.
The Impinj platform combines RFID readers, gateways, antennas, and endpoint ICs to give retail, logistics, healthcare, and industrial businesses real-time visibility into inventory, assets, and supply chains, enabling identification and tracking of everyday physical items — from retail merchandise and groceries to shipping pallets and packages. Impinj developed Gen2X, a standards-compatible enhancement to the RAIN radio standard, to add key solution innovations developed working with Fortune 500 enterprises. Gen2X unlocks enterprise use cases including shipment verification, fresh food management, and health & beauty inventory by enhancing tag readability, especially for small tags, tags in historically challenging environments or materials, and in densely packed containers.
Impinj has shipped more than 160 billion endpoint ICs worldwide and trades publicly under the ticker PI. Its technology unlocks Physical Intelligence, enabling everyday item identification at enterprise scale, providing operational insights so businesses can visualize everything, waste nothing, and act instantly.
Impinj's enterprise-grade hardware is trusted by major retailers and supply chain operators for its reliability and performance, making it a foundational partner for organizations building or scaling RFID deployments.

What Sets Impinj Apart
Impinj has been a driving force behind RAIN RFID since the technology's earliest days — from helping author the Gen2 standard that underpins it to co-founding the RAIN Alliance that promotes it. Over 25 years of R&D and real-world deployments at the world's largest retailers have made Impinj the standard other RFID providers are measured against. From chip design to reader hardware to software, here's what sets Impinj apart.
RAIN RFID Pioneer
Impinj helped author the Gen2 standard that underlies RAIN RFID and co-founded the RAIN Alliance in 2014. That early, hands-on role in shaping the technology informed the development of Impinj Gen2X, a standards-compatible enhancement to the Gen2 standard adding capabilities Impinj developed with Fortune 500 enterprises to solve real-world challenges.
End-to-End Platform
Impinj is one of the only companies that designs the full stack – endpoint ICs, readers and reader ICs, gateways, and software – so every component is engineered to work together, not just to spec.
Proven at Massive Scale
Impinj has shipped over 160 billion RFID chips, powering deployments at the world's largest retailers and supply chain operators. That scale demonstrates battle-tested reliability, not lab-only performance.
Industry-Leading Read Performance
Impinj AutoTune technology automatically optimizes each endpoint IC's performance for its environment, delivering longer read range and higher accuracy across materials, form factors, and frequencies.
Next-Gen Innovation (Gen2X)
Impinj is driving RAIN RFID forward with Gen2X, which speeds up inventory counts, extends read range, reduces environmental interference, and lowers overall solution cost. Gen2X is widely available and easy to deploy.
Global Partner Ecosystem
Impinj works with a broad network of tag converters, system integrators, and software partners, making it easier for businesses of any size to find a compatible, ready-to-deploy solution.

Frequently Asked Questions: Impinj
Which Impinj RFID reader is right for my application?
Choosing the right Impinj RFID reader depends on your environment, read range requirements, and application. The Impinj R700 RAIN RFID reader is the newest enterprise reader and is ideal for retail inventory, warehouse management, manufacturing, healthcare, and supply chain visibility. It offers faster processing, enhanced security, native IoT connectivity, and support for Impinj Gen2X features.
If you’re replacing an existing deployment or need a proven legacy platform, the Impinj Speedway R420 remains a reliable option for many fixed RFID applications - but is slowly being produced less and will likely be sunset in the coming years.
If you’re unsure which Impinj reader is best for your project, the Atlas RFID team can recommend the right hardware, antennas, tags, and accessories based on your requirements.

Does the Impinj R700 require PoE or PoE+?
The Impinj R700 supports Power over Ethernet Plus (PoE+) for full operation using a single Ethernet cable for both power and data. The reader can also be powered using an external power supply if PoE+ infrastructure is unavailable. For best performance, Impinj recommends using PoE+ or the approved external power supply.
Can Impinj readers work with antennas and RFID tags from other manufacturers?
Yes. Impinj RFID readers are designed to work with industry-standard UHF RAIN RFID equipment. The Impinj R700 can be paired with compatible antennas from many leading manufacturers, and it supports EPC Gen2 and Gen2X-compatible RFID tags from a wide range of tag suppliers. This flexibility allows organizations to choose the best combination of readers, antennas, and tags for their specific application.
