The 3D-Secure technology provides, in particular,
cardholder authentication for online purchases. |
 |
 |
| A common communication protocol between the retailer,
the receiving bank and the issuing bank, the 3D-Secure technology
(see
3D-secure payment: contents) was presented on Cartes Bancaires's
stand at the 2003 'Cartes' trade show. |
 |
 |
|
Card payment request |
| When making online purchases from
a retailer accepting 3D-Secure payments, the customer
enters, on the site, his/her bankcard number and
its expiry date. |
|
 |
|
 |
|
Authentication request |
| On receipt of the data supplied
by the customer, the MPI (retailer plug-in that
processes the payment operation) sends an authentication
request to the customer's bank. In return, it receives
a response signed with the customer's agreement. |
|
 |
|
 |
|
Authentication verification |
| The customer's bank asks the customer
to provide online authentication (for example, a
password). Its access control server checks the
authentication and forwards approval to the retailer. |
|
 |
|
 |
|
Authorisation request |
| The retailer's bank systematically
sends an authorisation request to the customer's
bank. The conventional electronic payment system
takes over the transaction from this point onward. |
