@GN bhai and others,
Kotak offers ActivMoney, which is a sweep facility FD. I have been using it since some months. Working fine. FDs are auto-created in multiples of 5k/10k for a fixed period of 6 months, and broken in multiples of this only on LIFO basis whenever required due to any withdrawal/debit.
It seems whoever guided you is himself not knowing or did not understand your query, but you can opt for it through the app, no need to visit branch etc.
Only downside is, the interest rate is 7% p.a. only on those funds which complete 6 months and mature. Otherwise rate of interest is significantly lower, even lower than saving account interest rate for some period.
