Yes, I did understand that too. In that case, the problem is: how can
I "match" two pairs of chips so that they will understand each other's
cyphertext without user intervention.

The may have the same initial seed and an algorithm for generating
successive keys (isn't this security by oscurity?) there the secrecy is
in the method and not in the key =/
