When you have already created an account you should activate it. The easiest way to do so is by simply opening the application and ordering the card. When you have created the account you will be prompted to order your payment card of choice.
Order it and it will transfer you to a new window where you will be asked to put in your current address of living in order for the Lanistar payment card to arrive at your doorstep. Once that is finished you will be prompted to undergo a KYC (Know Your Client) check to prove your identity.
When all of this is finished you will be done with the activation of your account.
