About Impinj
We and our partner ecosystem build item-visibility solutions using products that we design and either sell or license, including silicon radios; reading systems; tag design, manufacturing, test, encoding and commissioning systems, or collectively “tag production systems”; and intellectual property. We also offer software and cloud services, and while nascent from a standalone revenue perspective, they enable our other product offerings and we intend to expand them as a part of our growth strategy. We sell two types of silicon radios. The first are endpoint ICs that store a serialized number to wirelessly identify an item. Our partners embed endpoint ICs into an item or its packaging. These ICs may also contain a cryptographic key to authenticate the item.
