Method and system for using machine-readable codes to perform a transaction

A system for performing a transaction, the system comprising:

• a client transaction processor system comprising computer hardware, the client transaction processor system configured to:
• access a machine-readable code associated with a transaction, wherein the machine-readable code comprises transaction details associated with the transaction;
• translate the transaction details into a human-readable format to obtain translated transaction details;
• cause the translated transaction details to be presented to a customer user;
• and
• in response to receiving an acceptance response from the customer user, the client transaction processor is configured:
• to initiate payment to a merchant user;
• and
• access a second machine-readable code associated with a completed transaction, wherein the machine-readable code comprises transaction details associated with the completed transaction and wherein the completed transaction is based at least in part on the transaction.

A method of performing a transaction, the method comprising:

• receiving transaction details associated with a transaction;
• generating a machine-readable code associated with at least a subset of the transaction details;
• providing the machine-readable code to a customer computer system;
• in response to providing the machine-readable code, receiving payment confirmation information associated with a third-party payment system, wherein at least the generating is performed by a computer system comprising one or more processors;
• and
• in response to determining that the third-party payment system is a trusted third-party payment system, generating a second machine-readable code comprising completed transaction details.

A system for performing a transaction, the system comprising:

• a merchant transaction processor system comprising computer hardware, the merchant transaction processor system configured to:
• receive transaction details associated with a transaction;
• generate a machine-readable code associated with at least a subset of the transaction details;
• provide the machine-readable code to a customer computer system;
• in response to providing the machine-readable code, receive payment confirmation information associated with a third-party payment system;
• and
• in response to determining that the third-party payment system is a trusted third-party payment system, generate a second machine-readable code comprising completed transaction details.
