7. A method for the production of an information support upon which at least one piece of information is disposed, wherein a material layer covers information on the information support, the material layer bonding securely on the information and, upon destruction of the material layer, the material layer can be removed without damaging the information, the method comprising the steps of:
a) passing the information support, disposed on a conveyor belt, through a gap between an ultrasonic sonotrode and an anvil;
b) pressing, when passing through the gap and using the ultrasonic sonotrode, a hot-stamping strip, having a support strip with a colored layer, against the information support and against the anvil; and
c) releasing, during step b) and under activation of ultrasonic vibrations, an area section of the colored layer from the support strip to permanently attach that colored layer section over the information on the information support.
8. The method of claim 7, wherein a rotational sonotrode is utilized as the ultrasonic sonotrode and the anvil is borne for rotation and rotates for introduction of the colored layer onto the information support.
9. The method of claim 7, wherein a stationary or vertically displaceable sonotrode is utilized as the ultrasonic sonotrode whose head extends along a direction of passage of the conveyor belt, wherein the anvil can rotate or can be moved in a vertical direction during the covering procedure.
10. The method of claim 7, wherein a stationary sonotrode is utilized as the ultrasonic sonotrode having a head which extends transverse to a direction of passage of the conveyor belt, wherein, while covering the information, the anvil rotates or can be moved in a vertical direction.
11. The method of claim 7, wherein a plurality of ultrasonic sonotrodes and a plurality of anvils are disposed and utilized, one after the other.
12. The method of claim 7, wherein the information support is configured as a prepaid card for communication devices or for mobile telephones.
