Claim:
A method for completing a transaction relating to an account in which an account-holder is not required to know an account number and is not required to have an account card physically present during the transaction, the method comprising the steps of: linking a selected alias of the account-holder with the account number of the account and a selected personal identification entry, which is associated with the account number, in a database, wherein each of the selected alias and the selected personal identification entry is previously selected by the account-holder; effecting a transaction for the account-holder by receiving from the account-holder the selected alias; searching the database for the selected alias and the selected personal identification entry that is linked to the selected alias; prompting the account-holder for entry of an entered personal identification entry; accepting entry of the entered personal identification entry; authenticating the transaction upon determining that the entered personal identification entry entered by the account-holder matches the selected personal identification entry found through the database search; and performing the transaction for the account number once the transaction is authenticated; and wherein at least one of the selected alias and the selected personal identification entry includes both: a static portion, the static portion being a designated portion of the selected alias or selected personal identification entry that is not changed; and a dynamic portion, the dynamic portion being a designated portion of the selected alias or selected personal identification entry that is changed, the method further including the step of changing the dynamic portion of the selected alias or selected personal identification entry while not changing the static portion of the selected alias or selected personal identification entry.
