“Smart” Technologies Radio frequency identification (RFID) Integrated data read by radio waves (similar to merchandise control tags commonly used in stores). Data could be stored in a variety of ways, such as on a magnetic strip or memory chip. An example for use in gun technology is embedding a data chip in a watch or ring, with a reader embedded in the firearm. The firearm “recognizes” the user via the data chip, the safety disengages, and the gun can be fired. When originally examined by Colt, the iGun technology was designed for long guns; the project has largely been abandoned. Another version of this approach, called TriggerSmart, is under development by the Georgia Institute of Technology in Ireland. A design feature under development, known as “wide area control,” would allow a receiving device embedded in the firearm to be enabled or disabled remotely when entering designated areas, which has possible military application.
  Magnetic encoding Magnetically locks mechanisms of the gun and will unlock when in close proximity to the magnetic device, such as a magnetic ring. Existing technology is commercially available as retrofit installations under trade names such as Magloc and Magna Trigger.
  Biometric systems Automated devices that measure unique physical characteristics to identify and authenticate the authorized user. A number of different systems have been examined, including grip-pattern verification, fingerprint identification, and voice recognition. One system developed by the New Jersey Institute of Technology uses a gri-pverification approach called Dynamic Grip Recognition
