Metallic foil card and manufacturing thereof

A method of manufacturing a data carrier (1), suitable for use as a smartcard, comprising the steps of:

• Providing at least one carrier body (4);
• Providing at least one metallic foil (2);
• Providing at least one transferring element (8) temporarily in connection with the metallic foil (2),
• wherein the metallic foil (2) is transferred from the transferring element (8) to the carrier body (4) in a step of transferring, and the metallic foil (2) comprises one or more microcracks (3), wherein said step of transferring generates the microcracks (3) in the range of 1 micrometer to 900 micrometers as a result of the transferring element (8) being heated to a temperature in the range of 100° to 150°;
• and
• Providing at least one movement element in connection with the carrier body (4),
• wherein the movement element is moved along a movement direction while the metallic foil (2) is provided to the carrier body (4) in a step of moving,
• wherein the transferring element (8) is rolled about at least one rolling element (9) in a step of rolling,
• wherein the transferring element (8) is pressed onto the carrier body (4) in a step of pressing,
• wherein the metallic foil (2) is electrically non-conductive or essentially electrically non-conductive, and/or
• wherein the metallic foil (2) comprises an electrical conductivity that is less than 0.5 μS/m,
• wherein the thickness of the metallic foil (2) is 5 micrometer or less,
• wherein the metallic foil (2) comprises (i) one or more metals and/or (ii) one or more metal-containing compounds including organometallic compounds, and
• wherein the metallic foil (2) comprises or consists of aluminium and/or of one or more aluminium-containing coordination complexes, and
• wherein the step of rolling, the step of pressing, the step of heating and the step of transferring are performed simultaneously.
