Methods and systems of providing interoperability between incompatible payment systems

A system of mediating a payment, funded by a sender closed loop account in a first closed loop payment system, to a recipient closed loop account in a second closed loop payment system that is incompatible with the first closed loop payment system, the system:

• a server in a wallet connector system to:
• receive encoded data from a wallet server of the first closed loop payment system, the encoded data using an encoding scheme and being based on a digital encoding of a recipient;
• identify a receiving institution of the second closed loop payment system based on the encoding scheme;
• transmit the encoded data to the receiving institution;
• receive a response from the receiving institution, the response comprising a recipient identifier and a recipient attribute;
• and
• mediate the payment from the sender closed loop account to the recipient closed loop account based on the recipient identifier and the recipient attribute.

A system of mediating a payment from a sender account of a first payment system to a recipient account in a second payment system that is incompatible with the first payment system, the system comprising:

• a server to:
• receive, from a wallet server of the first payment system, sender identifying information identifying a sender, recipient identifying information that identifies a recipient associated with the recipient account, and a payment amount, the recipient identifying information being unknown to the first payment system;
• transmit the recipient identifying information to a plurality of payment systems, the plurality of payment systems including the second payment system;
• receive a response from the second payment system, the response comprising an indication that the recipient identifying information identifies a recipient that has an account associated with the second payment system and an attribute of the recipient;
• and
• mediate the payment from the sender account to the account associated with the second payment system based on the sender identifying information, the recipient identifying information, the payment amount, and the response.
