I generally purchase things like clothes or gadgets by card. It is definitely an easier way to purchase stuff. Actually, in South Korea, most people use cards instead of cash cause they don't need to carry a wallet. and I think every people know that coin is really heavy and it is really hard to put in a wallet. That is why I always use a card whenever I buy things but in the Philippines, a card is not as common as in Korea. So, whenever I go to a local market in the Philippines, I always bring cash. But in the future, I think if the Philippines become an industrialized country, definitely Filipinos will use card cause it is much more comfortable.
