Next, however, the e-passport has to be placed over an inductive reader that provides the radio-frequency energy to power up the passive RFID so it can spit out its data.
At present, proximity high frequency RFID (Radio frequency Identification) system based on inductive coupling load modulated technology is used worldwide.
