**Abstract:**
The concept of the (dual) binary discriminator was introduced by R. Halas, I. G. Rosenberg and the author in 1999. We study finite algebras having the (dual) discriminator as a term function. In particular, a simple characterization is obtained for such algebras with a majority term function.

**Keywords:** binary discriminator, majority function, compatible relation, finite algebra

**Classification (MSC2000):** 08A40, 08A05
