Around 1980 we had to use the puncher in my first Fortran class in the university. Later I bought a Z80-PC with an 8" floppy - what a progress! :-)

I thought I'd need a card puncher to write true Fortran ... (remembering that dangerous type of stack)

Our state (Germany) emits ID cards with chips to uniquely verify my identity with readers connected to the PC. Could be easy to establish a code signature instance based on these personal identifications (Only if our country wants digital progress :) )? I'm sure other at least european countries have similar mechanisms ...
