Dynamic currency conversion selection and control processing

Abstract:

A terminal receives card details for a payment card to process payment for a transaction. The card and transaction details are sent to an intermediate server. The card details are identified as being associated with a card issuer associated with a first currency while the terminal is associated with a second different currency from the first currency. A currency conversion entity selection request is sent to the card issuer. The card issuer requests a consumer select a currency conversion entity for payment at the terminal. A mobile device of the consumer generates encoded data representing: a selected currency conversion entity, the card details, and the transaction details. The encoded data is processed to verify and process payment for the transaction with the selected currency conversion entity preventing any override by a merchant to use a different currency conversion entity at the terminal.
