Inventory counts no longer have to elicit groans from retail employees: manual outdated methods are quickly being replaced by hands-free, always-on RAIN RFID solutions that offer unparalleled inventory insight and ease.

Accurate inventory data is key to an efficient, optimized retail organization. But many retailers are stuck doing things the old way—manually counting items. When the cycle count is complete, the data is quickly outdated. The Impinj platform uses RAIN RFID, an inexpensive battery-free technology that wirelessly connects information about an item’s identity, location and authenticity to enterprise retail systems. Accurate inventory information unveils a wealth of information that retailers need to confidently sell down to the last item in stock, know what products are popular, and understand how customers move and shop in their stores.

How it Works


Attach Impinj-powered RAIN RFID tags to items.


Use Impinj readers/gateways (handheld, overhead or on walls) to wirelessly identify and locate items in the store.


See accurate, real-time data about inventory across stores and distribution centers in enterprise retail systems.

"The better visibility customers have of inventory, the more likely they are to make a purchase: 74 percent of customers are likely to come into a store to buy an item if they know in advance the item is in stock, yet only 19 percent of Index retailers have an option to refine search results to show only what is available in store; only 44 percent provide store availability lookup on category or product detail pages."

  • Replace manual inventory counts with always-on RAIN RFID inventory intelligence

  • Maximize sales by optimizing on-shelf availability with RAIN RFID for retail

But stores using RAIN RFID technology can get automated replenishment reports that tell busy sales associates what items are needed on the sales floor. This simple and automated process means customers aren’t disappointed, and stores see increased revenue.
  • Optimize allocation of stock among distribution centers and stores 
    Too much inventory to stores means higher material handling, labor costs and clutter. And, maintaining the right stock levels at the distribution centers improves online fulfillment. But it’s hard to make the right decision when you’re guessing. With accurate inventory data, retailers make smart decisions about allocation that improves margins with less inventory in the supply chain.
  • Eliminate costly overstocking with retain RAIN RFID technology 
    With accurate inventory data, retailers can make their full line of products available to their customer, selling down to the last item no matter where it’s located – reducing the number of items marked down.
  • One platform to drive digital transformation across your retail business
