Letter: Letters: Behind bars

Published 26 March 1994

From ANDREW PETTIT

Q: There is a sequentially updated bar code appearing on the front cover
of copies of Â鶹´«Ã½. I have tried without success to decipher these.
How does the coding system (or any bar-coding system) work and how do bar
code readers work?
