Along with points, you must see if the best cash back card that you are going to select, is giving you extra perks or not. It is also important to know if the card is charging any fee whenever there is a foreign transaction. The other factor to consider is if the issuer is offering any protection for your trips and purchase. These are the things that can add important value to the card.
You also must know how much annual fee of the card they are going to charge you. Contact Maybank2u for more information on cash back cards.
