Data Timings for Magnetic Emulation
Fig. 5
The magnetic Emulation Sequence starts with the Card Present Line going active (down). There next
follows 10 clocks with Zero ‘0’ data. At the end of the 10 leading clocks the start character (11010) is
sent and this is followed by the data. At the end of the data the end character is sent followed by the
LCR. Finally 10 trailing clocks are sent and the card present line is raised.
The data bit duration is approximately 330uS. The approximate clock duration is 110uS. Because of the
symmetry data can be clocked off either the rising or falling edge of the clock.
