Electronics are embedded in the cookware, which monitor the food and send wireless signals to adjust the temperature of the induction heater accordingly; this prevents the loss of nutrients and saves thermal energy because the food is not overheated.

Each pan is embedded with a RFID tag in the handle of cookware, which is covered by a special pan tag that protects the RFID tag from heat and moisture. A temperature sensor connected to the RFID tag is imbedded within a tunnel in the bottom center of the pan. The RFID tag monitors the food 16 times per second and transmits a proprietary signal to the |induction heater regarding the heating characteristics of the contents as well as the temperature of the contents to adjust the heat accordingly; [cite web|url=http://www.ntv.co.jp/news/430/sakidori/20060222.html|title=調理ロボット|date=2006-02-22|publisher=Nippon Television|accessdate=2007-03-05|language=Japanese] cite web |url=http://www.vitacraft.com/rfiq/rfiq.html|title=What is RFIQin|publisher=VitaCraft|date=2005|accessdate=2007-01-02|language=English] the special pan tag is not battery powered and does not need to be recharged.cite web |url=http://www.vitacraft.gr.jp/rfiq/system.html|title=System|publisher=VitaCraft Japan|accessdate=2006-12-24|language=Japanese]

During the cooking process the food does not need to be monitored or stirred because the pans use waterless cooking methods and the induction heater uses alternating pulses to control the heat, so the liquid in the pans continually revolves in a circular motion. The RFIQin pans are built with a vapor seal that enables the pans to use techniques of pressure cooking.cite web |url=http://www.freshpatents.com/Pressure-cooker-dt20060601ptan20060112834.php|title=Pressure cooker patent invention|publisher= [http://www.freshpatents.com/ FreshPatents.com] |date=2006-06-01|accessdate=2007-01-03|language=English] The portable induction heater and cookware can be used in a manual mode as a regular induction heater.

Popular Science reported RFIQin will cost $600 dollars; [cite web|url=http://www.popsci.com/popsci/whatsnew/a21648e61178c010vgnvcm1000004eecbccdrcrd/39.html|title=The MegaGoods Gadget Review - Photo Gallery|publisher=Popular Science|accessdate=2007-03-05|language=English] however, in May 2006, The Sacramento Bee reported RFIQin costs $2,100 (241,500 Yen) in Japan.
