A conditional purchase offer (CPO) management system is disclosed for receiving CPOs from one or more customers, such as airline passengers, and for evaluating the received CPOs against a number of CPO rules defined by a plurality of sellers, such as airlines, to determine whether any seller is willing to accept a given CPO. A CPO rule is a set of restrictions defined by a given seller, such as an airline, to define a combination of restrictions for which the seller is willing to accept a predefined price. The CPO rules may be securely stored by one or more servers. The CPO management system permits a seller to correct for forecasting errors, if necessary, or other competitive forces which have produced excess capacity, by providing inventory for sale to CPO customers.

Some embodiments of the present invention provide for detecting a physical change (e.g., via a sensor of a transaction card), and, in response to detecting the physical change, producing an output signal promoting use of a financial account.

A conditional purchase offer (CPO) management system is disclosed for receiving CPOs from one or more customers, such as airline passengers, and for evaluating the received CPOs against a number of CPO rules defined by a plurality of sellers, such as airlines, to determine whether any seller is willing to accept a given CPO. A CPO is a binding offer containing one or more conditions submitted by a customer for purchase of an item, such as airline travel, at a customer-defined price. A CPO rule is a set of restrictions defined by a given seller, such as an airline, to define a combination of restrictions for which the seller is willing to accept a predefined price. The CPO rules may be securely stored by one or more servers. The CPO management system permits a seller to correct for forecasting errors, if necessary, or other competitive forces which have produced excess capacity, by providing inventory for sale to CPO customers.
摘要:
Methods and apparatuses are disclosed for computer-based evaluation of a test-taker's performance with respect to a reward threshold. A performance assessment of the test taker can be standardized or customized, as well as relative or absolute. The system allows a parentally-controlled reward system such that children who reach specified objectives can claim an award that parents are confident was fairly and honestly earned without the parent being required to proctor the testing.
