Abstract

A public access kiosk for conducting trusted lightweight e-commerce transactions. A trusted transactional cache and the associated transactional protocol allow e-commerce transactions to be committed to a remote server extremely quickly and with little network overhead. The end-to-end transactions are completed is just a few seconds allowing users to carry out e-commerce transactions without having to stand in front of the a display for minutes as is usually the case when making purchases on the Internet. The invention operates equally well on robust private networks as on unpredictable Internet or wireless networks, avoiding upsetting shoppers who would otherwise have to wait for the transaction to complete in the case of a temporary communication failure with the remote server or other failure. The methods and devices described herein may advantageously be used to offer large scale and cost-effective micro-payments solutions.

Claims

1. An electronic kiosk comprising:

a processor for controlling the kiosk;

a network interface to interface with a computer network;

a user interface enabling user interaction with the processor and initiation of a transaction with a remote server coupled to the computer network, the transaction including a plurality of execution sequences and associated plurality of critical states, and

a non-volatile cache memory configured to selectively store a context of the transaction, the context of the transaction including all information that is necessary for the processor to resume execution of the transaction at a beginning of an interrupted one of the plurality of execution sequences;

a context data save engine controlled by the processor for selectively storing the context of the transaction to the non-volatile cache memory at each of the plurality of critical states, and

a context data recovery engine controlled by the processor for retrieving the stored context from the non-volatile cache memory to enable the processor to resume and to complete execution of the transaction from the beginning of the interrupted execution sequence.

2. The kiosk of claim 1, wherein the non-volatile cache memory is solid-state.

3. The kiosk of claim 1, wherein the non-volatile cache memory includes a Non-Volatile Random Access Memory (NVRAM).

4. The kiosk of claim 3, wherein the processor is configured to execute the transaction in a first user session that concludes after the context data save engine has saved the context of the transaction to the NVRAM and a provisional acknowledgment is provided to the user and to execute a second remote server session that concludes after a confirmed acknowledgement is received from the remote server and provided to the user.

5. The kiosk of claim 4, wherein the user session is shorter in duration than the remote server session.

6. The kiosk of claim 1, wherein the context data save engine is configured to store the context of the transaction at least one of:

before sending the transaction to the remote server;

after sending the transaction to the remote server but before having received an acknowledgment of the transaction from the remote server;

after having received a continued acknowledgment of the transaction from the remote server.

7. The kiosk of claim 1, further including a printer controlled by the processor, the printer being configured to print at least one of human-readable information and machine-readable information.

8. The kiosk of claim 7, wherein the printer is configured to print an acknowledgment of the transaction.

9. The kiosk of claim 1, further including a reader controlled by the processor, the reader being configured to scan and decode printed machine-readable information.

10. The kiosk of claim 9, wherein the machine-readable information includes a barcode and wherein the reader includes a barcode reader.

11. The kiosk of claim 1, further comprising at least one of a magnetic and a smart card reader.

12. The kiosk of claim 1, wherein the user interface includes at least one of a display and a touch screen.

13. The kiosk of claim 1, wherein the processor is progrannned to cause the kiosk to:

enter a user session that exposes the user to messages and accepts user input to initiate the transaction via the user interface, commit the transaction to the non-volatile cache and provide the user with a provisional acknowledgment, and

enter a remote server session that commits the transaction to the remote server via the computer network by sending a single data packet that encapsulates all information necessary to initiate the transaction and to repeatedly re-send the single data packet until a valid acknowledgment is received from the remote server.

14. The kiosk of claim 13, wherein the processor is further programmed to ignore any duplicate data packet that is received from the remote server.

15. The kiosk of claim 1, wherein the kiosk is configured for public access.

16. A method of carrying out an online transaction between an electronic kiosk and a remote server, each of the kiosk and the remote sewer being coupled to a network, the method comprising the steps of:

initiating a transaction at the kiosk;

staring a copy of the transaction in a non-volatile memory within the kiosk;

sending the transaction to the remote server under a control of the kiosk, and

generating a provisional acknowledgment of the transaction from the copy of the transaction stored in the non-volatile memory when a confirmed acknowledgment is not received from the remote server within a predetermined period of time.

17. The method of claim 16, further comprising the step of:

receiving the confirmed acknowledgment from the remote server after the predetermined period of time and storing the received continued acknowledgment in the non-volatile memory.

18. The method of claim 17, further including a step of providing the stored confirmed acknowledgment upon request.

19. The method of claim 16, further comprising the step of re-sending the copy of the user transaction stored in the non-volatile memory to the remote server upon failure to receive the confirmed acknowledgment from the remote server.

20. The method of claim 19, wherein the re-sending step is carried out until a confirmed acknowledgment of the transaction is received from the remote server.

21. The method of claim 19, wherein the re-sending step is carried out a predetermined number of times.

22. The method of claim 16, wherein the generating step includes a step of printing the provisional acknowledgment together with corresponding machine-readable information that uniquely identifies the transaction.

23. The method of claim 16, wherein the generating step includes a step of printing the provisional acknowledgment together with machine-readable information uniquely identifying the transaction and wherein the method further includes a step of the kiosk reading the machine-readable information and providing the stored confirmed acknowledgment that corresponds to the read machine-readable information.

24. The method of claim 23, wherein the stored confirmation acknowledgment providing step includes a step of printing the confirmation acknowledgment.

25. The method of claim 16, wherein the kiosk includes a user interface that enables user interaction with the kiosk and wherein the initiating step includes a step of providing user credentials and selecting goods and/or services for purchase via the user interface.

26. The method of claim 25, wherein the user credentials include at least one of identification and payment instrument information.

27. The method of claim 16, wherein the initiating step includes a step of encapsulating all information required for the remote server to process the transaction into a single data packet and wherein the storing and sending steps store and send the single data packet in the non-volatile memory and to the remote server, respectively.

28. The method of claim 27, wherein the information required for the remote server to process the transaction includes at least one of:

user credentials including at least one of an identity of the user;

payment instrument information;

delivery information, and

information identifying the subject matter of the transaction.

29. The method of claim 27, flitter including a step of encrypting the single data packet prior to the sending step.

30. The method of claim 16, further comprising a step of receiving a confirmed acknowledgment of the transaction from the remote server and providing the confirmed acknowledgment.
