<p>This invention relates to a method to set Personal Identification Numbers (PINs) used in authenticating the identity of users of electronic transaction terminals, credit cards, financial accounts, or any other systems requiring entry of predetermined numeric codes for authorization to perform a transaction or access data. This is achieved by placing an automated voice call to the mobile phone of the user, performing a security check by asking a security question, upon successful completion of the security check, asking the user to enter the desired PIN, and storing this value as the PIN of the said card, or account for this user.</p> |
