A viable way of preventing fraud or abuse of Bank Cards (Credit and/or Debit ) that can be established by creating a Primary Account which is accessed and linked to a User's Bank Card in the customary manner and that normally contains no funds (supposing that overdra ft protection is not in effect for this account). In normal use, the Principal Owner of the Primary Bank Ca rd would transfer funds from a Subsidiary Deposit Account (Savings Account) or a Subsidiary Credit Account (Line of Credit, Credit Card Account, etc.) which could be linked to the Primary Account by virtue of the ir ownership, and also by various stored procedures (software or hardware) which could be effected by their Primary Owner, for the transfer of funds between these accounts, after the introduction of a Second Security Code into the Computer Terminal, Automatic Banking Machine, Telephone, etc., used to aces the bank accounts in the normal manner. Only the Number of the Primary Bank Card is given out by its Principal Owner to be used in Debit or Credit Transactions so as to maintain security in relation to th e Subsidiary Deposit Account(s) (Savings Account(s)) or the Subsidiary Credit Account(s) (Line(s) of Credit, Credit Card Account(s), etc.).
