The paper deseibes a new type of feature information card-images feature information card based on self-drawn figure by user(IIC).The Paper construets the mathematical models which are fit to the relation between geometries true ture of dynamic sampling IIC installing strueture of sensor;According to the method of vertical and horizontal inclining gradually，we take advantage of infrared double-diodeto arrange IIC pattern information and make use of software and hardware to collect it alternately and dynamically;The PaPe reonstruets electric eireuit models of sampling system of IIC;The paper proposes various effective algorithm storestore primitive double-value electronic image twisted for need of sampling to the original electronic image.At the same time，the sampling algorithm of IIC in combination with software and hardware reflectvivid features.IIC has some outstanding advantages，sue has eonvenient applieation，cheap hardware cost，ingenious bulk，distinet and reliable result integrated software with hardware.Because of the advantage of self-drawnfigurebyuser，IICwouldhave broad developing and applying prospect in lots of domains，sue has door-lock，authority management，pattern reeognition and its manipulation，etc.
