Authentication outlets are special outlets supporting authentication based on Sony NFC*/FeliCa technology currently applied in contactless IC cards used as transit tickets and e-money. Authentication relies on two elements-the plug connected to electric appliances or electric vehicles, which contains a IC chip , and the outlet itself, which incorporates a contactless IC card reader/writer. When devices are plugged in, the system conducts authentication to identify the device and owner. Because the IC chip in the plug can be used for e-money purchases and keeping track of energy consumption, the system enables individualized billing, as well as energy management for each device. An added safeguard is that no power passes through the plug until authentication is completed, preventing the risk of electric shock if foreign objects are inserted by mistake.

Two types of authentication outlet under development
Here, authentication applies Sony NFC/FeliCa contactless IC card technology. A IC chip in the device's plug is read by a reader/writer in the outlet.
RFID* Authentication Over Power Line
Contactless IC card technology is combined with new RFID Over Power Line technology. A central reader/writer is located at an electric switchboard, for example, and each device plugged in is authenticated via power lines. This eliminates the need to have a reader/writer in each outlet, which reduces system construction costs.
*RFID: Radio-frequency identification
Not only can authentication outlets help cities build the charging infrastructure for electric vehicles, it can help us establish electricity service systems for a changing world. In coming years, Sony will continue to work with manufacturers in fields of power distribution, appliances, and residential development toward practical implementation of authentication outlets.
