We consider the double parton scattering (DPS) initiated by direct photons in <a:math xmlns:a="http://www.w3.org/1998/Math/MathML" display="inline"> <a:mi>γ</a:mi> <a:mi>p</a:mi> </a:math> and <c:math xmlns:c="http://www.w3.org/1998/Math/MathML" display="inline"> <c:mi>γ</c:mi> <c:mi>A</c:mi> </c:math> collisions. We extend the previously known results for photoproduction to the case of electroproduction with nonzero photon virtuality <e:math xmlns:e="http://www.w3.org/1998/Math/MathML" display="inline"> <e:msup> <e:mi>Q</e:mi> <e:mn>2</e:mn> </e:msup> </e:math> , and then consider the DPS for both photo and electroproduction for HERA and EIC (electron ion collider) kinematics. The number of DPS events at the EIC is shown to be of the same order as in HERA and is even larger, with increase in luminosity compensating the decrease of the center-of-mass energy.
