As ecommerce fraud management experts recommend, the simplest method is to keep a card only for Internet transactions. The second way to e-commerce fraud protection is to always redirect the amounts in the card account to the savings account when they exceed a specific value. That is if your package of products and services also includes a savings account. In this way, the balance of your card used for online transactions will always be anemic. Every time he makes a purchase, the cardholder will move the money from the savings account to the account attached to the card; every time he has a payment, he will transfer the excess amounts back to the savings account.
