I only agreed your partly statement. You can transfer your fund to other bank via GIRO service through several channels. We can transfer our fund to others bank in Malaysia via 3 methods. ATM, Internet Banking, and OTC(over the counter). ATM and Internet Banking allowed us to transfer up to MYR5K per transaction per day. And that's the limit through self-service. While you done your transaction via OTC, there's is not limited. The only limit is depends how much credits in your account. Last year I did transferred OTC about MYR50K via GIRO from Bank A to Bank B. They only charged me RM2.00 and takes 3 days for clearance.
