Abstract

A computerized method for generating a time-limited number for use in a payment card transaction involving a payment card issued by a financial institution. The payment card comprises an original payment card number. A first plurality of digits of the original payment card number is provided to a processor. The first plurality of digits are predetermined digits associated to the financial institution. A desired expiration date through which the time-limited number is valid for acceptance in the payment card transaction is provided to the processor. A program is executed by the processor to set a first plurality of digits in the time-limited number to the first plurality of digits in the original payment card number, generate a first number corresponding to the desired expiration date, set a second plurality of digits in the time-limited number to the first number, and output the time-limited number.

Claims3

Dependent claims

A computerized method for identifying an account assigned to a user by an institution, wherein the institution associates the account with validation data that the institution requires to be supplied by the user to allow the user utilization of the account, and with an identifier that distinguishes the account from other accounts maintained by the institution for other users, and wherein a credential comprises a combination of the validation data and the identifier, comprising the steps of:

providing a computing device having a processing device;
and
providing a media that stores computer-executable instructions that cause the computing device to execute the steps of
receiving, at the computing device, controlled by the user, a first part of the credential from the institution, wherein the first part comprises a first portion of the validation data and a first portion of the identifier;
receiving at the computing device from the user a second part of the credential, wherein the second part comprises a second portion of the validation data and a second portion of the identifier and wherein a combination of the second part with the first part completes the credential;
and
transmitting the credential from the computing device, via a wide area network, to a receiving server with a request to conduct a transaction with the institution based on the account.
