Abstract
The invention provides a two-sided auxiliary structure for induction cards, which comprises: a metal shield layer; and two high-conductivity magnetic layers, which are respectively set on two opposite sides of the metal shield layer, wherein the area of the metal shield layer is greater than those of the two high-conductivity magnetic layers. The two-sided auxiliary structure for induction cards of the invention improves the problem of poor induction success rate of plural induction cards.
