Abstract
A process for manufacturing a hybrid card, and a hybrid card which functions as a smart card with flush contacts and/or produces acoustic signals which can be transmitted by telephone. The card includes a first sheet that has on one of its surfaces an interconnection pattern and electronic components, and through the body of the first sheet perforations for a double faced micro module (10). A second sheet is on an opposite face of the card. An intermediate sheet is between the other two sheets and has cut-outs (210, 215) in which are housed electronic components affixed to the first sheet, and has metal coatings (260) for making electrical connection to the micro module (10) and also to the interconnection pattern (110) on the first sheet (100).
