These credit cards are reward cards with free insurances. Platinum card has five insurances while Signature has six. Minimum income apply. These are the best fee free credit cards I can find to date: no annual fee + 0% BT offer + reward points(1.25/1.5 per $) + comprehensive insurances. Enjoy.
Edit: this has been extended to the end of March or July 2014.
I have a few cards with total credit limit exceeding 20k and was approved… balances owing on the cards are not much and usually paid off on time (unless I forget!).
