  We consider tachyon effective theory with Born-Infeld electromagnetic fields
and investigate the configurational entropy of the various tachyon kink
solutions. We find that the configurational entropy stats at a minimum value
and saturates to a maximum value as the negative pressure of pure tachyonic
field increases. In particular, when an electric field is turned on and its
magnitude is larger than or equal to the critical value, we find the
configurational entropy has a global minimum, which is related to the
predominant tachyonic states.
