  Fix a finite group G and an n-dimensional orthogonal G-representation V. We
define the equivariant factorization homology of a V-framed smooth G-manifold
with coefficients in an $E_V$-algebra using a two-sided bar construction,
generalizing [And10, KM18]. This construction uses minimal categorical
background and aims for maximal concreteness, allowing convenient proofs of key
properties, including invariance of equivariant factorization homology under
change of tangential structures. Using a geometrically-seen scanning map, we
prove an equivariant version (eNPD) of the nonabelian Poincare duality theorem
due to several authors. The eNPD states that the scanning map gives a
G-equivalence from the equivariant factorization homology to mapping spaces out
the one-point compactification of the G-manifolds when the coefficients are
G-connected. For non-G-connected coefficients, when the G-manifolds have
suitable copies of R in them, the scanning map gives group completions. This
generalizes the recognition principle for V -fold loops spaces in [GM17].
