A system provides an efficient way of providing electronic accounts to customers over a public network, in which all payments are traceable, i.e. anonymity is available to the degree that the customer provides an account number for paying for the transaction, and that uses as much as possible of emerging public network payment protocols. One embodiment of the system handles small payment from customers to merchants without burdening the banks with each small transaction by aggregating the payment at a payment gateway from the customers and to the merchants.

An authorization system allows for cardholder-provided parameters to a personal authorization subsystem. The parameters can be selected by the cardholder to limit the authorizations that would otherwise be granted on the card. The parameters can indicate limits by frequency, dollar amount, merchant, geographic location, time of day, combinations thereof, or the like. Authorization for a given transaction, even where authorized by an issuer and a network operator, might be denied based on self-constraints set by the cardholder. In some variations, messages are sent to the cardholder based on constraints set by the cardholder and transactions might be approved and messaged, or denied and messaged.

A check acceptance system provides interactive authorizations and off-line terminal approvals. A merchant uses an interactive transaction terminal to communicate with a check acceptance service's authorization host computer. The terminal includes an electronic check reader and a magnetic stripe reader for reading magnetic stripe drivers licenses. The terminal acquires transaction data associated with a pending check transaction. The transaction data is analyzed to determine whether the transaction can be approved by the terminal. If so, an approval code is generated and a transaction packet including the transaction data and terminal approval code are stored in the terminal until subsequent communication with the host computer. If the pending transaction is not approved by the terminal, the transaction data is transmitted to the host computer. The host computer applies a risk scoring algorithm to the data to determine whether the transaction should be approved, declined, or whether additional information is needed. If the transaction is approved or declined, a response packet including authorization indicia is transmitted to the terminal. If additional data is needed, the host computer transmits prompts to the terminal. The terminal displays the prompts and the merchant enters the requested data into the terminal. A new transaction packet including the original transaction data and the additional requested data is transmitted to the host computer, where it is approved or declined.

A system and method for accelerating customer sales transactions in a retail store. A customer checkout accelerator provides a customer user interface to initiate a request for a preapproval amount for a sales transaction before reaching the point of sale terminal for completion of the purchase transaction. A card reader integrated into the customer checkout accelerator reads a customer payment card number when the payment card is swiped through the reader. A customer checkout accelerator server module resident on a store controller server determines a preapproval amount for the sales transaction and transmits the request to an external card services system for payment approval. The customer checkout accelerator also provides the ability to purchase additional promotional items in the checkout lane with this process integrated into the payment preapproval process. Once payment approval is obtained from the external card services system, an entry is placed in a preapproval database associated with the customer checkout accelerator server module on the store controller server. The server module forwards the approval notification to the point of sales terminal where it is placed in a preapproval cache for use in completing the actual sale transaction.

This is an expenditure data recording system using a uniquely designed classification binary code (or its equivalent) stored within the point of sale terminal system consisting of a cash register, a credit/debit card reader, and a telecommunications line. In a sales transaction, a credit/debit card passes through this reconfigured point of sale terminal not only to furnish relevant information (date/time, vendor identification, cardholder's name and account number, and transaction amount), but also to classify the expenditure by category via instant telecommunications link upon approval by the credit/debit card issuer (financial institution). Whenever there is a needed classification change at the point of sale terminal, one utilizes a unique set of color, binary-encoded cards to redefine a new expenditure category. Whereupon the credit/debit card issuer can process this classified expenditure sales transaction information to produce a periodic financial report, and remit it to the credit/debit account holder at any time. This entire operational system is virtually transparent to the cardholder and sales personnel.
