    Abstract: A method for producing a smartcard body for receiving a semiconductor chip includes forming at least one lead frame of the smartcard body in a carrier material connected by at least one material strip. Surrounding the at least one lead frame is an electrically insulating casing having a cavity for receiving the semiconductor chip. Either before or during the forming of the casing, the at least one material strip is separated or severed, so that the material strip is separated into a first strip part connected with the carrier material and a second strip part connected with the lead frame forming an interspace there between. When forming the casing at least a portion of the first strip part as well as at least a portion of the second strip part of the at least one material strip is comprised by the casing.
