Credit Card Slave

I'm all set to fly, was worried about my credit card limit as I'll be there with CXOs. Colleagues lifted my worries when he told me that credit card can be use as debit card as well. All I have to do is to transfer some money into it in advance.

Eg.
My credit limit = RM15K
Transfer = RM5K
Swipeable (my own word) amount = RM20K

Viola!

ps. I'm glad that I didn't know about this because it means I've never over spend :P
