We consider the Minkowski embedding space of the Reissner-Nordstrom solution to show that the embedding space plays the same role as the Kruskal maximal extension. We point out that a static observer in Reissner-Nordstrom exterior geometry is a particular kind of uniformly accelerated observer in the six-dimensional Minkowski embedding space and therefore he experiences a thermal bath of Rindler particles. However, since the static observer is restricted to a 4-D manifold, his horizon, unlike accelerated observer's horizon, is finite and so is the entropy.
