Identiv expands ID-Safe NFC tags, offering tamper detection and secure traceability to enhance product authenticity and ...

A cryptographic tag uses terahertz waves to authenticate items by recognizing the unique pattern of microscopic metal particles that are mixed into the glue that sticks the tag to the item's surface.

At every turn, networks must handle additional traffic from new sources. One of the latest and soon-to-rise sources of increased network traffic arises from the implementation of radio frequency ...

After passing through the tag and striking the object’s surface, terahertz waves are reflected, or backscattered, to a receiver for authentication. A few years ago, MIT researchers invented a ...
