MIT researchers have developed a new tiny cryptographic ID tag with revolutionary terahertz technology, making it smaller, cheaper, and more secure than traditional radio frequency tags (RFIDs). The latter are often attached to products to verify authenticity but can easily be compromised by counterfeiters who remove and reattach them to fake products. To combat this,…

Researchers at MIT have developed a cryptographic ID tag that is significantly smaller, cheaper, and more secure than traditional radio frequency identification (RFID) tags. The new tag is based on the use of terahertz waves which are smaller and have much higher frequencies than radio waves. The innovation overcomes a major security flaw common with…

MIT researchers have created a secure and portable ID tag, utilizing terahertz waves, a technology considered superior compared to traditional RFIDs due to the improved security it offers. The team has bypassed the significant vulnerability of both RFID and terahertz tags, where a counterfeiter can remove the tag from an original item and transfer it…
