Two bank accounts, one 360, and one Frank, both with OCBC. All incomes and major transactions all go thru the 360, but there is no ATM access. I transfer my monthly allowance from 360 to the Frank on 26th of each monthly (feels like pay day!!). The Frank account is the only one that I can access with my atm card. 1) I love this arrangement because everytime I go to the atm, I see available balance and am reminded how much left there is and whether to tighten the belt a bit. 2) the giro deductions can easily clear from 360, with no insufficient balance and 10 charge for failed transaction. 3) easier for bank reconciliation and how where your monies is going mainly by reading the flows in 360, and not the miscellanous small charges. 4) better security I guess. Its rather tough to touch my money in the 360, without going thru online banking, and even if so, 80% of the funds are locked down in savings goals. I used to want different banks for the two accounts, but I didnt feel it was a necessity. Besides when I do my qtrly balance sheets, I just need to login one bank. Also I consider if I have two much money in the bank, some of it must be not working hard enough. Invest the rest I say.
