 Smart
Cards
Typical applications are marking of Smart Cards such as ID cards,
phone cards for cellular phones and credit cards. The possibilities
of marking covers photos, text and/or barcodes. There are basically
2 different ways of marking these cards. Due to the extreme short
pulses the lower layer of so called multi layer cards can be marked
by changing the colour of the pigments without touching the transparent
top layer. The other way to mark is to create 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 save.
