Laser Marking of Smart Cards
Typical applications are marking of Smart Cards such as ID cards and credit cards. The possibilities of laser marking covers photos, text and/or barcodes. There are basically two different ways of laser marking these cards.
- Due to the extreme short pulses the lower layer of so called multi layer cards can be marked by changing the color of the pigments without touching the transparent top layer. Even high-resolution, greyscale images are possible.
- Tactile laser marking creates a kind of recast on the top layer. This kind of marking can be found e.g. on all European EC cards where the name, card and account number is marked that way. The combination of the above mentioned methods makes these cards fraud safe.
