Abstract: A method for imposing fees on a merchant includes: storing, in a merchant database, a plurality of merchant profiles, wherein each merchant profile includes data related to a merchant in violation of a rule or regulation including at least a merchant identifier; receiving, by a receiving device, an authorization request for a payment transaction, wherein the authorization request includes at least a specific merchant identifier associated with a merchant involved in the payment transaction and a transaction amount; identifying, in the merchant database, a specific merchant profile where the included merchant identifier corresponds to the specific merchant identifier; processing, by a processing device, the payment transaction for the transaction amount; processing, by the processing device, a second payment transaction for the imposition of fees on the merchant involved in the payment transaction; and processing, by the processing device, a third payment transaction for revocation of the transaction amount.

Abstract: A method for identifying a level of authentication includes: storing a plurality of authentication processes, each tool being associated with transaction characteristics; storing a plurality of account profiles, each profile including account data and an account identifier; receiving an authorization request for a payment transaction, the request including transaction data and a specific account identifier; identifying at least two eligible authentication processes based on the transaction characteristics for the respective tool and the transaction data; identifying a specific account profile that includes the specific account identifier; estimating a profitability value of the transaction based on the transaction data; estimating an account purchase elasticity value based on the account data included in the identified specific account profile; and selecting one or more authentication processes of the identified at least two eligible authentication processes based on the estimated profitability and account pu

Abstract: A method for providing an assured currency exchange rate includes: storing, in an account database, an account profile, wherein the account profile includes data related to a payment account including at least an account identifier, a conversion rule, and a period of time; receiving, by a receiving device, an authorization request for a payment transaction, wherein the authorization request includes at least the account identifier, a transaction amount in a first currency, and a transaction time and/or date that is within the period of time; calculating, by a processing device, a new transaction amount in a second currency based on application of the conversion rule to the transaction amount in the first currency; updating, by the processing device, the authorization request to include the calculated new transaction amount in the second currency; and forwarding, by a transmitting device, the updated authorization request.
