Here is a list of websites from which you can invest online with your Folio number and PAN number. You will be asked to register an email id the first time. I could find the websites for some AMCs including HDFC, Reliance, BirlaSF, DSPBR, ICICI, Sundaram etc. Please add to this list if you have more.
If you are a new investor (without a Folio number), you have to fill out some paperwork and go via CAMS or Karvy.
For HDFC, use: https://investor.hdfcfund.com/MFonlineForm/ExistingFolio.aspx
For BirlaSF, use: https://www.birlasunlife.com/BirlaSunLife/Mutual_Fund/BSLAMC_Mybsfs/DontHaveCIPTPIN_MF.aspx
and http://mutualfund.birlasunlife.com/ManageInvestments/InvestNow/tabid/100/Default.aspx
For Reliance: https://converz.karvymfs.com/ReliancePOM/online/ExistingUser.aspx
For DSPBR: http://www.dspblackrock.com/services/epayin.asp
(online investments are NOT possible, i think)
For ICICI, use: https://www.icicipruamc.com/InvOnline/invest.asp
For Sundaram, use: http://www.sundarambnpparibas.in/invest_online/io_essentials.php
For IDFC MFs, use https://mfonline.idfc.com/AddPur_IDFCWebClient/
For CanaraRobeco, I could not find it
Good luck investing online and save time and money
