Abstract

A card-based system electronically transfers funds in real time. A customer card stores digital data representing a unique customer account number associated with a unique, remotely located customer account having at least one vendor-associated subaccount. A merchant terminal having a merchant IP address designating a unique merchant is affiliated with at least one unique vendor for transmitting to a system control center customer transaction data including the merchant IP address, the customer account number read from the customer card and account adjustment data designating either the value of a credit to be added to the vendor-associated subaccount reflecting a customer pre-payment or the value to be subtracted from the vendor-associated customer subaccount reflecting a customer purchase. The system control center maintains a vendor account database and a customer account database. The customer account database associates each customer account number with the unique customer account number, stores the subaccount credit balance corresponding to the specified vendor, receives the customer transaction data transmitted by the merchant terminal, adjusts the customer subaccount value up or down in response to the customer transaction data, transmits to the merchant terminal customer account status information and adjusts the vendor account database to reflect credits resulting from vendor-associated customer transactions.

Claims

1. A card-based system for electronically transferring funds in real time comprising:

a. a customer card for storing digital data representing a unique customer account number associated with a unique, remotely located customer account having at least one vendor-associated subaccount;

b. a merchant terminal having a merchant IP address designating a unique merchant affiliated with at least one unique vendor for transmitting to a system control center customer transaction data including the merchant IP address, the customer account number read from the customer card and account adjustment data designating either the value of a credit to be added to the vendor-associated subaccount reflecting a customer pre-payment or the value to be subtracted from the vendor-associated customer subaccount reflecting a customer purchase; and

c. the system control center for maintaining a vendor account database and a customer account database, the customer account database associating each customer account number with the unique customer account number, for storing the subaccount credit balance corresponding to the specified vendor, for receiving the customer transaction data transmitted by the merchant terminal, for adjusting the customer subaccount value up or down in response to the customer transaction data, for transmitting to the merchant terminal customer account status information and for adjusting the vendor account database to reflect credits resulting from vendor-associated customer transactions.

2. The card-based system of claim 1 further including a vendor datalink for transmitting data between the vendor and the system control center for enabling a vendor to access and review the vendor database.

3. The card-based system of claim 2 wherein the vendor datalink is established via the Internet.

4. The card-based system of claim 1 further including a wireless datalink network for transmitting data between the merchant terminal and the system control center.

5. The card-based system of claim 1 further including an Internet datalink for transmitting data between the merchant terminal and the system control center.

6. The card-based system of claim 1 further including a remote credit card database and a credit card datalink for transmitting data between the system control center and the credit card database.

7. The card-based system of claim 6 wherein the credit card database is coupled to the system control center via the Internet.

8. The card-based system of claim 7 further including an Internet data interface for enabling a customer having a customer card to access the customer account database on the system control center via the Internet and for enabling the customer to transfer funds from the remote credit card database to the customer account database.

9. The card-based system of claim 1 wherein the merchant terminal designates a merchant affiliated with first and second vendors.

10. The card-based system of claim 1 wherein the customer account database includes multiple subaccounts wherein each subaccount corresponds to a unique vendor and wherein the credit balance of each subaccount can be adjusted independently of the credit balances of the other subaccounts.
