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.

Traditional radio-frequency identification (RFID) tags, commonly used for product authentication, have several limitations including size, cost, energy requirements, and security vulnerabilities.

MIT researchers have developed a new iteration of their anti tampering ID tag using terahertz waves as per a report published on the official MIT website on February 18. This tiny tag is said to be ...

Unlike traditional RFID tags, which are known for their size, cost, and susceptibility to counterfeiting, MIT stated in its press release that this innovative cryptographic chip utilizes terahertz ...

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 ...

(Nanowerk News) A few years ago, MIT researchers invented a cryptographic ID tag that is several times smaller and significantly cheaper than the traditional radio frequency tags (RFIDs) that are ...
