  We construct contact interactions for bosonic and spinning strings. In the
tensionless limit of the spinning string this reproduces the super-Wilson loop
that couples spinor matter to Abelian gauge theory. Adding boundary terms that
quantise the motion of charges results in a string model equivalent to spinor
QED. The strings represent lines of electric flux connected to the charges. The
purely bosonic model is spoilt by divergences that are excluded from the
spinning model by world-sheet supersymmetry, indicating a preference for spinor
matter.
