Where do you get the impression that the online transaction is foc? 

The GIA is available in maybank2u as eGIA-i under fixed deposit section

Any bank transfer within the bank is free 

Yes, however GIA you can uplift everything, where as m2u saver you are tied with the minimum balance of 250 in that account

Moreover, m2u saver does not give interest below 2000 (same rate as bsa for the islamic m2u saver)

And yes, GIA interest is calculated daily, and when you uplift, it will give you the interest equals to the day you put in according to the monthly interest rate as quoted in their website

Yes. Not important. However if you select 1 month you need min rm5k.

be mindful that accessing eGIA is from 6am till 10.30pm, 7 days a week including public holidays.

If the sum is minimal n extremely short duration, it's not worthwhile as u need to login for placement n withdrawal

Planning to do ut when I get my credit card. After all this is my SA now. Anytime need money just uplift. Simple. What's a few minutes compare to totally zero interest (interest in normal SA is negligible)

yah, I'm doing this.

egia serial number already reaching #65 lol

I see. Then I just need to ensure my balance is more than 2k by night time. Tq very much.

If is let say 9.30pm, then we can exploit it with GIA-i account. Everyday morning withdraw the GIA-i to earn 3.5%, then put at savings account until 9.30pm to get another 2%, then put back at GIA-i @ 9.45pm.
