RFID Chip

Hospitals are major consumers of RFID tags for supply chain management, but these electronic tags also serve as real time locators for medical staff workers and even patients. The RFID system, then, becomes a potential site for a hacker intent on causing disruption, distraction or destruction. To address this security issue, electrical engineers at MIT and Texas Instruments have designed a RFID tag that works almost like the World War II “Enigma” cypher machine. While this piece doesn’t make a point of medical applications, virtually every electronic device—environmental, wearable, implantable, ingestible—might benefit from improved encryption function.
