'Inspired by a car wash': Researchers unveil quasi-universal tag that's virtually unhackable thanks to glue — terahertz antitampering tag could help save billions of dollars in counterfeiting costs

Cryptographic ID tag .

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

Researchers at MIT have developed a revolutionary cryptographic ID tag that overcomes these hurdles and could help combat the billion-dollar problem of supply chain counterfeiting.
