Predictive authorization techniques

1. A method comprising:

receiving an authorization request for a transaction over a network, the authorization request including account information and transaction information specifying at least a transaction amount;

identifying a financial account from the account information;

predicting future debiting and crediting of the account based on a history of the financial account;

predicting a balance of the financial account based on the predicted future debiting and crediting of the account, the predicting the balance of the financial account including generating a payment window for at least one credit to the account, the payment window specifying a time period within which the at least one credit is expected;

determining whether the predicted balance of the financial account is sufficient to support the transaction for the transaction amount, the determining based in part on the payment window; and

generating an approval response to the authorization request based on the determining.

2. The method recited in claim 1 wherein:

the financial account comprises a debit account; and

the predicted balance of the financial account is greater than or equal to the transaction amount.

the transaction is for a purchase by a customer from a merchant; and

the authorization request is received from the merchant,

the method further comprising transmitting the approval response to the merchant.

16. The method recited in claim 13 wherein the predicting the balance of the financial account at the specified future time comprises an estimate of a reliability of the prediction.

17. A system comprising:

a communications device;

a processor;

a storage device; and

a memory coupled with the processor, the memory comprising a computer-readable medium having a computer-readable program embodied therein for directing operation of the system to process a transaction, the computer-readable program including:

instructions for receiving, with the communications device over a network, an authorization request for the transaction, the authorization request including account information and transaction information specifying at least a transaction amount;

instructions for identifying, with the processor, a financial account from the account information;

instructions for predicting, with the processor, future debiting and crediting of the financial account based on a history of the financial account;

instructions for predicting, with the processor, a balance of the financial account based on the predicted future debiting and crediting of the financial account, the predicting the balance of the financial account including generating a payment window for at least one credit to the account, the payment window specifying a time period within which the at least one credit is expected;

instructions for determining, with the processor, whether the predicted balance of the financial account is, sufficient to support the transaction for the transaction amount, the determining based in part on the payment window; and

instructions for generating, with the processor, an approval response to the authorization request based on the determining.

18. The system of claim 17 wherein:

the financial account comprises a checking account;

the predicted balance of the financial account is greater than or equal to the transaction amount;

the transaction comprises payment using a check drawn on the checking account; and

the account information includes an account number obtained by reading a magnetic-in character-recognition (“MICR”) line from the check.

19. The system of claim 17 wherein:

the financial account comprises a credit account; and

a difference between a credit limit of the credit account and the predicted balance of the financial account is greater than or equal to the transaction amount.

20. The system of claim 17 wherein the instructions for predicting future debiting and crediting of the financial account comprise separate instructions for analyzing actions that increase the balance of the financial account and actions that decrease the balance of the financial account.

21. The system of claim 17 wherein:

the transaction is for a purchase by a customer from a merchant; and

the authorization request is received from the merchant,

the computer-readable program further includes instructions for transmitting the approval response to the merchant.

22. The system of 17 wherein the instructions for predicting, with the processor, the balance of the financial account comprise instructions for predicting, with the processor, a balance of the financial account at a specified future time.

23. The system of claim 22 wherein the specified future time comprises a time interval.

24. The system of claim 23 wherein the prediction of the balance of the financial account at the specified future time comprises a prediction of a minimum balance of the financial account over the time interval.

25. The system of claim 22 wherein the prediction of the balance of the financial account at the specified future time comprises an estimate of a reliability of the prediction.

26. A machine-readable medium having sets of instructions stored thereon which, when executed by a machine, cause the machine to:

generate a model of at least one characteristic of a financial object over time from historical information;

receive data defining an action to be taken with the financial object;

predict future debiting and crediting of the financial object based on the historical information;

predict a future state of the financial object based on the predicted future debiting and crediting, the predicting the future state including generating a payment window for at least one credit to the account, the payment window specifying a time period within which the at least one credit is expected;

predicting an effect of the action based on the input data and the predicted future state of the characteristic of the financial object, the predicting the effect of the action based in part on the payment window; and

decide whether to take the potential action based on the predicted effect.

27. The machine-readable medium recited in claim 26 wherein the financial object comprises a financial account.

28. The machine-readable medium recited in claim 27 wherein the characteristic of the financial object comprises a balance of the financial account and the future state of the characteristic comprises a predicted balance of the financial account.

29. The machine-readable medium recited in claim 28 wherein the historical information comprises a record of withdrawals of funds from the financial account.

30. The machine-readable medium recited in claim 27 wherein the historical information comprises a record of deposits of funds to the financial account.

32. A method comprising:

receiving an authorization request for a transaction over a network, the authorization request including account information and transaction information specifying at least a transaction amount;

identifying a financial account from the account information;

predicting, independently of a current balance of the financial account, a balance of the financial account based on the predicted future debiting and crediting of the financial account, the predicting the balance of the financial account including generating a payment window for at least one credit to the account, the payment window specifying a time period within which the at least one credit is expected;

determining whether the predicted balance of the financial account will support the transaction for the transaction amount, the determining based in part on the payment window; and

generating an approval response to the authorization request based on the determining.
