Signing the contract is the last step in the process of opening the account. After confirming that you have read and accepted the contract, you will receive an SMS on the mobile phone number you provided at the beginning of the process, or a notification from the app, with the confirmation code that you must enter where indicated. This signature system is as valid as a handwritten signature.
Remember that a copy of the signed contract will be available in the My Profile/My Documents section of your remote banking.
