To use your Netcoins exchange virtual card, follow these steps:
Log in to your Netcoins exchange account and click on the "Virtual Cards" option in the menu.

Once the card is activated, you can use it to make online purchases wherever Visa or Mastercard is accepted.
When making a purchase, enter the card details (card number, expiration date, and security code) at the checkout.
The purchase amount will be deducted from your Netcoins exchange balance, so make sure you have sufficient funds in your account before making a purchase.
