Abstract
An improved contactless sensing device comprises a cover plate, a case, a base, a light-guiding module, a printed circuit board, and two lateral plates. When the sensing device senses a credit card containing a specific tag, a plurality of second light-emitting elements on the two lateral plates emit light of specific colors. The light is displayed on a light-permeable sensing element of the cover plate through the light-guiding module and a second opening of the housing.
