Method and system for creating a unique identifier

Apparatus for creating a second unique identifier based on a first unique identifier, the apparatus comprising at least one memory including computer program code, and at least one processor in data communication with the at least one memory, wherein the at least one processor is configured to:

• receive, from a user terminal operated by a user, the first unique identifier, wherein the first unique identifier is a primary account number;
• identify a first system based on the first unique identifier, the first system being different from the user terminal;
• initiate a first authentication process based on the first unique identifier;
• and
• responsive to the user successfully authenticating during the first authentication process:
• receive user data from the first system;
• generate, by a second system, based on at least a part of the user data associated with the first unique identifier in the first system, at least a part of the second unique identifier, the second unique identifier being different from the first unique identifier;
• storing, by the second system, the first unique identifier;
• receiving, by the second system, the second unique identifier from the user terminal;
• and
• initiating, a payment transaction using the stored first unique identifier and the at least part of the user data.

A non-transitory computer-readable medium comprising computer-executable instructions which, when executed by a processor, cause a computing device to perform a method of creating a second unique identifier based on a first unique identifier, the method comprising:

• receiving, by a second system from a user terminal operated by a user, the first unique identifier, wherein the first unique identifier is a primary account number;
• identifying a first system based on the first unique identifier, the first system being different from the user terminal;
• initiating a first authentication process based on the first unique identifier;
• and
• responsive to the user successfully authenticating during the first authentication process:
• receiving, by the second system, user data from the first system;
• generating, by the second system, based on at least a part of the user data associated with the first unique identifier in the first system, at least a part of the second unique identifier, the second unique identifier being different from the first unique identifier
• storing, by the second system, the first unique identifier;
• receiving, by the second system, the second unique identifier from the user terminal;
• and
• initiating, by the second system, a payment transaction using the stored first unique identifier and the at least part of the user data.
