The invention relates to an information support (12) comprising at least one information provided on said support (12), characterized in that said information is covered by a material layer which is triggered via an ultrasonic sonotrode (18) from a hot-stamping strip (24). According to the invention, the material layer is transferred to the information support (12) at the position where an information stored on the information support (12) is to be covered. The transfer of material layers to information supports by means of ultrasonic sonotrodes enables operations to be carried out in an easy and rapid manner at low temperatures. The ultrasonic sonotrodes operate preferably in a frequency range of 15000 to 35000 Hz. The information support (12) can also be configured as a support that receives a material layer without an information on the support being covered.
(ZH) 本发明涉及一种信息载体(12)，它具有至少一种设置在信息载体(12)上的信息，该信息由一个通过一个超声焊极(18)从一个热压条(24)取下的材料层覆盖，并且在此，材料层在要覆盖一个沉积在信息载体(12)上的信息的位置转送到信息载体(12)上。利用借助一个超声焊极将材料层转送到信息载体上的方式，可在低温下快速而低廉地进行加工。超声焊极优选在15,000－35,000Hz的振动范围内工作。信息载体(12)也可构造为接收材料层的载体，而不覆盖载体上的信息。
