EFID is the Electronic Flight Instrument Display (EFID). Flight instruments mainly include attitude instrument, navigation instrument and aircraft status instrument. Attitude instrument is an instrument that displays aircraft attitude, mainly consisting of horizon instrument, altimeter, speedometer, glide speed indicator, Angle of attack overload indicator, etc. Navigation instrument mainly includes integrated compass, inertial navigation guide, satellite, magnetic compass, beacon compass, tacan navigation and auxiliary landing indicator, etc. Aircraft status instruments are mainly fuel meter, consumption meter, engine tachometer, temperature meter, brake pressure gauge, hydraulic pressure gauge, etc., in addition to the navigation meter, and a signal plate composed of various signal lights.
Radio Frequency identification (RFID) is a wireless communication technology that can identify a specific target through radio signals and read and write related data without establishing mechanical or optical contact between the identification system and the specific target.
Such an IC card is actually an EFID tag, which is an application of RFID, so there is no comparison. You can think of IC cards as RFID tags, but RFID tags are not just IC cards. It is only one aspect of RFID application.
