A method and apparatus for conducting a commercial transaction over the Internet or other network connection are provided. The method includes the use of random numbers which are unique for each user session. These random numbers are pre-loaded onto a handheld, portable device, token, at the time of the device's manufacture or programming. These numbers are generated by external systems. The external systems then deliver the number sets to the token for storage in the token's internal memory and also to another random number database that is accessible by an authentication system. The random numbers are dispensed by the token to a user by pressing a button on the token or otherwise signaling the token. A simple polynomial equation may be employed in order to increase the number of codes. A dispensed number is cross referenced, by the authentication system, to the random number database that was created when the token was programmed. In this way the user or transaction can be authenticated. In its preferred configuration, it is intended that once the total number of random combinations, including the original random numbers and numbers generated by polynomial transformations, have been exhausted, the device becomes inoperable.

What is claimed is: 1. A token for conducting commercial transactions comprising: a power source; a memory storing a unique set of predetermined random numbers and software, when executed causes the token to perform the steps of: selecting and dispensing an unused number from the set of predetermined random numbers, wherein the set of random numbers is identical to a set of numbers stored in an external authentication system; a plurality of buttons wherein each button is assigned a unique account identification number representing an account for conducting a commercial transaction, and said buttons for selecting and dispensing a previously unused number from the set of random numbers using the software; and displaying means for displaying the dispensed numbers and said unique account identification numbers. 2. The token for conducting commercial transactions according to claim 1 wherein the token becomes inoperable when the unique set of random numbers becomes exhausted. 3. The token for conducting commercial transactions according to claim 1 further including a communications port, wherein the token may be reprogrammed via the communications port with a new set of random numbers by an external system when the unique set of random numbers becomes exhausted. 4. The token for conducting commercial transactions according to claim 1 further including 1 to N predetermined polynomial transformation equations, wherein the 1 to N predetermined polynomial transformation equations operate on each random number to provide 1 to N additional numbers for each of the predetermined random numbers. 5. The token for conducting commercial transactions according to claim 1 further including a magnetic transducer, wherein the software is configured to cause the magnetic transducer to generate magnetic pulses according to the selected button for emulating the conventional magnetic strip of a standard credit/debit card and, wherein the magnetic pulses represent one of the dispensed random number with the unique account identifier and predetermined credit/debit card identification numbers programmed for each of the buttons. 6. The token for conducting commercial transactions according to claim 1 further including a PIN number, wherein the software is configured to request a user to enter the predetermined PIN number each time the token is activated, and wherein the software is configured to not dispense a random number until the correct PIN number has been entered. 7. The token for conducting commercial transactions according to claim 6, wherein the PIN number is entered by selecting the appropriate buttons, and wherein there are sufficient buttons to represent each digit of the PIN number. 8. The token for conducting commercial transactions according to claim 6 further including a keypad, wherein the PIN number is entered by selecting appropriate keys on the keypad. 9. The token for conducting commercial transactions according to claim 1, wherein the power source includes at least one of a battery and a solar cell, and wherein the solar cell may optionally generate sufficient power from interior lighting. 10. A device for conducting commercial transactions comprising: a power source; first memory for storing a unique set of predetermined random numbers, second memory storing software when executed causes the device to perform the steps of: selecting and dispensing an unused number from the set of random numbers, wherein the set of random numbers is identical to a set of numbers stored in an external authentication system; a plurality of buttons wherein each button is assigned a unique account identification number representing an account for conducting a commercial transaction, and said buttons for selecting and dispensing a previously unused number from the set of random numbers using the software and displaying means for displaying the dispensed numbers and said unique account identification numbers. 11. The system for conducting commercial transactions according to claim 10 further including a communications port, wherein the system may be reprogrammed via the communications port with a new set of random numbers by an external system when the unique set of random numbers becomes exhausted. 12. The system for conducting commercial transactions according to claim 11, wherein the communications port may be connected to at least one of the Internet and a cellular network. 13. The system for conducting commercial transactions according to claim 10 further including 1 to N predetermined polynomial transformation equations, wherein the 1 to N predetermined polynomial transformation equations operate on each random number to provide 1 to N additional numbers for each of the predetermined random numbers. 14. The system for conducting commercial transactions according to claim 10 further including a PIN number, wherein the software is configured to request a user to enter the predetermined PIN number each time the system is activated, and wherein the software is configured to not dispense a random number until the correct PIN number has been entered. 15. A code dispensing device comprising: a power source, first memory for storing a unique set of predetermined random numbers; second memory storing software when executed causes the code dispensing device to perform the steps of: selecting and dispensing an unused number from the set of random numbers, wherein the set of random numbers is identical to a set of numbers stored in an external authentication system; a plurality of buttons wherein each button is assigned a unique account identification number representing an account for conducting a commercial transaction; means for selecting and dispensing a previously unused number from the set of random numbers using the software and displaying means for displaying the dispensed numbers and said unique account identification numbers. 16. The code dispensing device according to claim 15, further comprising: a power source for powering the dispensing device. 17. The code dispensing device according to claim 16, wherein said power source includes a photo-electric device. 18. The code dispensing device according to claim 15, further comprising: indicator means for indicating to a user of the dispensing device an amount of undispensed codes remaining in the storage means. 19. The code dispensing device according to claim 15, wherein each code is only dispensed once.
