I will be looking over www.mfcentral.com , which is a website run jointly by CAMS and Kfintech. All the MF entries go through these two companies. This website is supposed to be a one stop solution for all things MF. You can get your MFs with different brokers directly on this one website using your PAN card.
MFU is founded and run by all MF AMC to give centralized platform.
The drawback with these platforms is that they dont give DEMAT units, so one cant pledge or for other things like LAS etc which requires units to be blocked for collateral.
