In the past, most people thought we should not own too many credit cards as it might lead to over-consumption or missing payment. With the development of modern society and more credit card offers, many of us own several credit cards for various purposes, such as one for overseas spending, one for earning Asia Miles, and the other one for monthly installments.
Keep in mind that if you always pay your credit card bills after the due date while owning many credit cards, your credit score may drop, which is likely to affect your credit card, mortgage and loan applications.
