There are two ways of taking payments: Offline and Online.
Offline
An offline payment method is a payment method that does not involve any kind of online transaction. There are two types:
Non-Credit Card: e.g. 'EFT / Direct Bank Payment', 'Cheque on Delivery', 'Cash on Delivery', 'Invoice with Order' etc..
These are payment methods where the payment details are sorted out by directly contact with the customer after receiving the order.
Online
If you want people to pay for the goods whilst they are online then you need to use a 'Payment Service Provider'.
A Payment Service Provider (or 'PSP') is a third party company who specialise in taking credit / debit card payments online.
Your online customers are passed to the server belonging to the PSP when they are ready to pay for their order. They enter their details into the PSP page, and then the PSP contacts their bank, validates the card and takes the payment. The PSP then passes the payment to you at a later time.

Virtual Card Services are fully 3D-Secure compliant. 3D-Secure (3 Domain Security) is a new method of security mandated by the Card Associations to enhance the security of online transactions. Mastercard's product is called "SecureCode" and Visa's product is called "Verified by Visa".
The 3D-Secure refers to three domains involved in the security they are
the Acquiring or Merchant's bank
the Card Association's financial networks ie Mastercard and Visa
the Issuing or Cardholder's bank.
Very simply the system authenticates the cardholder before the transaction takes place by diverting the browser to the bank that issued the card, who then request some secret, perhaps a pin, from their cardholder that will conclusively prove that this actually is the cardholder entitled to use this card. Once they are satisfied that this is their cardholder they issue an authentication receipt which is then presented to the merchants bank along with the authorisation request. If the transaction is then approved by the issuing bank they may not charge the transaction back to the merchant because the cardholder disputes the transaction as not being originated by them.
