1. Make sure that the cashier of the store does not read the card twice. With two readings, the first reading will be your payment for the purchase, while the second reading will be a second reading, allowing others to embezzle the price of your purchase.
2. The cashier who has memorized the CVV number or the 3-digit code on the inside of the card and the remaining 16-digit number when the card is read becomes fully available for online shopping. 80% of bank card theft is done in this way, and only in the United States and England, the amount of money victims of this theft exceeds 1 billion dollars per year.
To be careful:
- Be careful not to have your card read twice. Check your account.
-Warn against giving the opportunity to see the 3-digit code.
- If possible, get a separate card for online shopping and don't use it every day
