New payment security measures will be introduced from 14 September 2019 in response to a change in the law. The new system is called SCA (Strong Customer Authentication) and will apply whenever you make a purchase from any retailer, including Alensa.
Extra security checks will become more frequent when you're paying online. These are applied at random and you'll be asked to authenticate the purchase by entering a unique one-use passcode, which your card issuer will send to your phone.
You may have been asked to authenticate with 3D Secure when paying online before, however with the new regulation comes a new process, offering better security and easier ways to authenticate.
However, your bank may have defined an entirely new process to improve your payment experience. Some banks have designed a new smartphone application specifically for this purpose. Please get in touch with your bank for more information.
Make sure your card issuer or bank has your most up-to-date phone number, so that they can send the passcode to you, and that you have your phone to hand when you place an order.
