>		Summary :
SuperKEKB e+e- collider is designed to provide a very high luminosity for Belle-II experiment, using nano-beam scheme. In this context, the fast luminosity monitoring collaboration aims to develop a reliable instrumentation to measure the luminosity and provide fast input for luminosity feedback corrections as well as for luminosity optimization phase. The measurements are based on the detection of the electron or positron arising from the Bhabha scattering process at zero degree photon angle, which offers a significant amount of signal. The fast luminosity monitoring system will be set at few meters downstream the interaction point, ideally both in the High and Low energy rings, just immediately outside the beam-pipe. Several kind of detectors are under development, combining thus complementary technologies, namely scintillator, Cerenkov counter and diamond sensor, all requiring fast readout electronics enabling both the measurements of the whole-ring averaged luminosity and the bunch by bunch luminosity.
