FeliCa is externally powered, i.e. it does not need a battery to operate. The card uses power supplied from the special FeliCa card reader when the card comes in range. When the data transfer is complete, the reader will stop the supply of power. FeliCa was proposed for ISO/IEC 14443 Type C but was rejected [citation needed].
