1. A portable data carrier, comprising:
- data storing and processing apparatus;
an antenna for transmitting energy and information, the antenna being connected to the apparatus; and
a plastic surrounding the apparatus and the antenna;
wherein the plastic of the portable data carrier is transparent or partially transparent and the antenna includes at least one security feature,wherein the entire antenna and the entire security feature are visible through the plastic,wherein the at least one security feature is disposed on either or both of an inner or outer surface of the antenna,wherein the security feature of the antenna comprises at least one of a pigment, a micro particle, a color capsule, or a coating,wherein at least a color of the at least one of pigment, micro particle, color capsule, or coating changes in dependence on a temperature of the security feature, wherein the at least one of pigment, micro particle, color capsule, or coating emits light in a first spectral range when the security feature has a first temperature and emits light in a second spectral range when the security feature has a second temperature.

35. A method for producing a contactless data carrier having:
-
an antenna that is printed or produced of wire or etched, an apparatus for storing and processing data which is connected to the antenna, and a plastic body enclosing the apparatus and the antenna, wherein the plastic body is transparent or partially transparent, and wherein the entire antenna and the entire security feature are visible through the plastic body, the method comprising the step of; either or both of applying at least one security feature on a surface of the antenna, or mixing the at least one security feature with a material of the antenna, including using as the security feature at least one of a pigment, a micro particle, a color capsule, or a coating, wherein a color of the pigment, micro particle, color capsule, or coating changes in dependence on a temperature of the security feature, wherein the at least one of pigment, micro particle, color capsule, or coating emits light in a first spectral range when the security feature has a first temperature and emits light in a second spectral range when the security feature has a second temperature. - View Dependent Claims (36, 37, 38, 39, 41)
