We study the effects of non-commutative QED (NCQED) in fermion pair production, gamma + gamma to f + f and Compton scattering, e + gamma to e + gamma. Non-commutative geometries give rise to 3- and 4-point photon vertices and to momentum dependent phase factors in QED vertices which will have observable effects in high energy collisions. We consider e+ e- colliders with energies appropriate to the TeV Linear Collider proposals and the multi-TeV CLIC project operating in gamma gamma and e gamma modes. Non-commutative scales roughly equal to the center of mass energy of the e+e- collider can be probed, with the exact value depending on the model parameters and experimental factors. The Compton process is sensitive to LambdaNC values roughly twice as large as those accessible to the pair production process.
