The present invention relates to a hybrid card reader for a smart phone capable of bi-directionally reading a magnetic card for convenient usage, improving the efficiency of electricity usage by having the self-generating function by a solar cell and a micro motor and being formed in a compact structure. The device of the present invention comprises an earphone plug which is inserted into an earphone jack of the smart phone to transmit an speaker output and a micro signal; a hybrid electricity distribution module which generates electricity from the speaker output of the earphone plug or supplies power by using the electricity of a solar cell or a micro motor generator; a pair of magnetic heads which are provided to read the magnetic card in the both sides; an encoder which encodes data detected from the magnetic heads; a encoding module which encodes the encoded readout data; a readout data output module which alters the encoded readout data to an audio signal to be transmitted to a microphone input end of the earphone plug; an earphone speaker distribution module which connects a signal of the earphone plug to an extension earphone jack when earphones are connected to the extension earphone jack while outputting the speaker output received from the earphone jack of the smart phone by the speaker; and a microprocessor which controls the entire operation.
