To combat supply chain counterfeiting, which can cost companies billions of dollars annually, MIT researchers have invented a cryptographic ID tag that's small enough to fit on virtually any product and verify its authenticity.

Wireless ID tags are becoming increasingly popular for authenticating assets as they change hands at each checkpoint.

Popular radio-frequency identification tags are too large to fit on tiny objects such as medical and industrial components, automotive parts, or silicon chips.

"If I want to track the logistics of, say, a single bolt or tooth implant or silicon chip, current RFID tags don't enable that. We built a low-cost, tiny chip without packaging, batteries, or other external components, that stores and transmits sensitive data."

Finally, they wanted cryptographic protocols because RFID tags can be scanned by essentially any reader and transmit their data indiscriminately.
