Ohh!! Thanks!
I was impressed in this one
The Institute of Mathematical Machines exhibited its IMMVein terminal for infrared identification of people by the pattern of the veins on their hands, which is unique for each individual.I've never heard this identification system using vein. Interesting!
Information Technology I guess.
Yeah, it's well know. I heard the biggest computer science university in EU is in Poland (Silezja...? I forgot). Polish computer science will be more developed in future, won't it.
