Actually, there is no approximate time for this. In general, if you change businesses, you'd better brush it again every half an hour.

However, there is also a special situation. If you swipe your credit card (debit card) across provinces and cities, you'd better swipe it the next day. After all, it is difficult to do cross-provincial transactions for half an hour. Otherwise, you must be using your credit card (debit card) to swipe your credit card (debit card) illegally.
