Abstract: An electronic card for electromagnetic data exchange, the electronic card including an electronic circuit (2) which is contained in a housing (1), the housing (1, 1′) being provided with a bottom element (10) and a top element (20), the electronic circuit (2) being contained between inner surfaces (10′, 20′) of the bottom and top elements (10, 20). At least one of the bottom element (10) and the top element (20) is provided with at east one recess (11, 12, 21, 22, 11a, 12a, 21a, 22a), into which the electronic circuit (2) is inserted, the shape (11′, 12′, 21′, 22′, 11a′, 12a′, 21a′, 22a′) of the recess (11, 12, 21, 22, 11a, 12a, 21a, 22a) corresponding to an outer shape (2a′, 2b′, 2c′; 2a′, 2c′) of the electronic circuit (2), the electronic circuit (2) being at least partially covered by the top element (20), and the housing (1; 1′) being encased by a sheathing (50) made of plastics.
