Systems and methods for performing payment transactions using indicia-based associations between user interfaces

A system for indicia-based payment transaction, the system comprising:

• a data storage device storing instructions for performing an indicia-based payment transaction;
• a server that hosts a site that is displayed on an external user interface;
• a first user device having a user interface;
• and
• a processor configured to execute the instructions to perform a method including:
• receiving, from a merchant device of a merchant, transaction information related to a selection of goods or services from the merchant;
• generating or receiving an indicia encoded with the transaction information and encoded with additional information including payment preferences of a user;
• transmitting the indicia to be displayed, the display of the indicia enabling the first user device to scan the indicia and extract information related to the transaction information;
• receiving, subsequent to (i) the indicia being scanned by the first user device, and (ii) the indicia-based payment transaction being authorized on an application, of the first user device, that was opened in response to the indicia being scanned by the first user device, an authorization from the merchant device of the merchant to process the indicia-based payment transaction;
• generating and transmitting a token indicating the authorization of the indicia-based payment transaction to the merchant device of the merchant, wherein the token conceals information related to the indicia-based payment transaction;
• and
• processing the indicia-based payment transaction using the token.

A non-transitory machine-readable medium storing instructions that, when executed by an indicia-based payment system, cause the indicia-based payment system to perform a method for performing an indicia-based payment transaction, the method including:

• receiving, from a merchant device of a merchant, transaction information related to a selection of goods or services from the merchant;
• generating or receiving an indicia encoded with the transaction information and encoded with additional information including payment preferences of a user;
• transmitting the indicia to be displayed, the display of the indicia enabling a first user device to scan the indicia and extract information related to the transaction information;
• receiving, subsequent to (i) the indicia being scanned by the first user device, and (ii) the indicia-based payment transaction being authorized on an application, of the first user device, that was opened in response to the indicia being scanned by the first user device, an authorization from the merchant device of the merchant to process the indicia-based payment transaction;
• generating and transmitting a token indicating the authorization of the indicia-based payment transaction to the merchant device of the merchant, wherein the token conceals information related to the indicia-based payment transaction;
• and
• processing the indicia-based payment transaction using the token.
