Document Type and Number:
WIPO Patent Application WO/2017/196075
Kind Code:
A1
Abstract:
The present invention relates to a device for transmitting data and, particularly, to a device for transmitting data by using a magnetic stripe method. According to one embodiment of the present invention, the magnetic stripe data transmission device comprises: a coil to which a current is supplied in a first direction and a second direction, which is opposite to the first direction; a core for inducing a magnetic field when the current is supplied to the coil; a power source for supplying the current to the coil; driving units for intermittently supplying, to the coil, in the first direction or the second direction, a pulse or pseudo-pulse current supplied from the power source; and a control unit for outputting, to the driving units, a control signal in order to perform control such that the current is supplied to the coil alternately in the first direction and the second direction, wherein the core can be made of a material having an aspect ratio value of at least 0.5, having a coercivity value of 1000-10,000 [A/m], and having pseudo-hard magnetic density of which the saturated magnetic flux density value is at least 1[T].
