Impinj Protected Mode

The Protected Mode feature provides a secure, flexible, easily reversible, and high-speed method to make tag data invisible to RAIN RFID readers.

Increase privacy, performance and flexibility of RAIN RFID systems

Enterprise systems need to comply with consumer privacy regulations while maintaining operational efficiency and flexibility. To meet these requirements, systems need to control when and where tagged items are read and prevent tag data from being shared with unauthorized readers. With Impinj Protected Mode, a RAIN RFID system can determine when and where a tag will respond to a reader request for data.  

Available on select Impinj RAIN RFID tag chips and readers, RAIN systems use Impinj Protected Mode to:  

  • Comply with emerging privacy regulations by making tagged items invisible to unauthorized RAIN RFID readers 
  • Increase RAIN system performance by focusing readers on the right tags 
  • Help secure the supply chain by preventing tagged items from being read by unauthorized readers 

Impinj Protected Mode use in retail and supply chains

Retail automated self-checkout Enhance the shopping experience with fully automated self-checkout systems that don’t require an employee to remove a security device. 
Retail loss prevention Improve the performance of loss prevention systems by making tags on purchased items no longer visible to RAIN RFID security portals.
Retail omnichannel fulfillment Optimize sales with real-time accurate inventory data, updated as tags are automatically deactivated when products are sold and no longer available to online shoppers.  
Retail returns and inventory management Streamline return processes and reduce fraudulent returns by reactivating tags to access product and purchase data. With the original purchase confirmed, the item can be added back to store inventory without re-tagging.  
Supply chain and logistics Strengthen supply chain security by controlling when sensitive or high value tagged items are visible to RAIN RFID readers during transit.

How Impinj Protected Mode works

Most RAIN RFID tags respond to any RAIN RFID reader inquiry with the tag’s EPC data -- including readers that are not part of the enterprise’s RAIN RFID system. Using a secure password, the reader enables Impinj Protected Mode and the tag becomes invisible to all readers. A tag with Protected Mode enabled does not respond to a reader unless the correct password is included with the reader query command. And, using the password, a RAIN RFID reader can turn Protected Mode on and off to control when and where tags can be read. 
Impinj RAIN RFID readers use the standard GS1 Gen2 commands (Select, Access, and Write) to control whether Protected Mode is on or off. The password is a 32-bit value that can be set by the user or within a RAIN RFID application.
