Tools/Materials Credit Card Methods/Steps 1 Credit cards have a billing date and a repayment date, and the longest time of these two dates can reach 45 -55 days. In other words, let's spend the credit card first and wait for more than a month to return it. If we can make good use of this month, then we can use credit cards to save money, so as to make money.
We can help others shop and let others give us cash, which we can use to manage our finances. As soon as the date arrives and the principal is paid back, the income from financial management will be ours.
Nowadays, many people use POS machines to swipe their cards. I don't agree. It's dangerous. In order to cash in, you have to pay a handling fee. If you make money by investing in cash, the risk is too great. I don't recommend doing this.
It is also a kind of making money to spend more with credit cards, save points, exchange points for goods, and then sell the goods below the market price.
