First of all, go to the mall to cash out, which is normal consumption. The key depends on whether the other machine has points. If there are points, it will be safe, and if there are no points, it will be unsafe.

Secondly, it doesn't cost much to buy a new card for the first time. First, it is safe to go to the supermarket to buy dozens of credit cards.

Third, don't spend a lot of money every time you swipe your card. It is best to take the number after zero. It is safe to use it frequently.

Finally, don't swipe your card on a machine without points, otherwise it is easy to have an accident.

I hope I can help you.
