When making an online purchase, you must enter your card details to proceed with the payment if you have chosen to pay by card.
Once you click on "pay", a screen of your bank opens where you have to enter the OTP code received via text message or App.
Once the code has been entered, the payment is finalized.
We recommend that you contact your credit institution for more precise and complete information.
If you have a credit card with which you usually shop online and you have not yet activated the two-factor service (3DS), you will not be able to make the payment. This is because your bank will ask you to enter a special OTP security code (One Time Password, i.e. a disposable code / password) or to access your online banking app to authorize the payment. The only solution is to contact the institution that issued your card and proceed with the activation of this security system.
