Abstract

A method for entering the serial number into the nonvolatile memory of an electronic postage meter upon completion of assembly of the meter including the steps of programming a given chip number into a nonvolatile memory to be used in assembly of the meter, assembling the electronic postage meter with a meter body serial number and a nonvolatile memory with a given chip number, communicating the serial number and chip number to a data center, receiving information from the data center in response to the communicating steps, and entering the serial number into the nonvolatile memory if the received information is properly enterable into the meter. In accordance with further aspects of the present invention, an intercommunication system is provided for entering a serial number into the nonvolatile memory of an electronic postage meter upon completion of assembly of the meter, a data center communicates a serial number to the electronic postage meter after assembly of the meter, and an electronic postage meter is provided into which a serial number is enterable upon completion of assembly of the meter.

Claims

1. An intercommmunication system for communication between a data center of the type that stores postage meter information and electronic postage meters each of which has a nonvolatile memory wherein the intercommunication system supplies information for the entering of a serial number into the nonvolatile memory upon completion of assembly of each meter, comprising:

the data center having storage means for storing a chip number and a seed number for each nonvolatile memory to be used in assembly of the electronic postage meters;

first communicating means for communicating the serial number and chip number of each of the assembled meters to said data center;

data center receiving means for receiving the serial numbers and chip numbers;

generating means located within the data center for generating seed numbers associated with said chip numbers;

second communication means for communicating respective serial numbers and seed numbers to each of the electronic postage meters;

electronic postage meter receiving means located in each postage meter for receiving information from said data center in accordance with its respective serial number and seed number;

means for selectively entering the information from said data center into each electronic postage meter;

means for indicating acceptance of the information by each of the electronic postage meters;

means for writing the serial number in the nonvolatile memory upon acceptance of the information by each electronic postage meter; and

means for preventing further writing into the nonvolatile memory where the serial number is written.

2. The intercommunication system recited in claim 1, including:

means for preventing further writing in the data field of the nonvolatile memory where the serial number has been written.

3. The intercommunication system recited in claim 1, wherein:

said communicating means includes a data link.

4. The intercommunication system recited in claim 1, wherein:

said communicating means includes a voice answer-back unit.

5. A method for entering a serial number into a nonvolatile memory of an electronic postage meter that is communicatingly connectable with a data center of the type that stores postage meter information and is communicatingly connectable with a plurality of postage meters, wherein the electronic postage meter is assembled within a case having the serial number assigned thereto, the serial number being entered upon completion of assembly of the electronic postage meter, comprising the steps of:

generating chip numbers for entering into a plurality of nonvolatile memories,

storing the chip numbers in the data center;

entering one of said chip numbers into the nonvolatile memory to be used in assembly of the electronic postage meter;

assembling the electronic postage meter having the serial number and including the nonvolatile memory with said one chip number;

upon completion of the assembly, communicating the serial number and said one chip number to the data center;

deriving reset information at the data center based upon the serial number and chip number in response to the communicating step;

transmitting the reset information from the data center to the electronic postage meter;

confirming the reset information is properly enterable into the nonvolatile memory;

entering the serial number into the nonvolatile memory if the information received is properly enterable; and

preventing further writing into the nonvolatile memory where the serial number is written.

6. The method recited in claim 5, including the steps of:

deriving a seed number based upon the chip number, and

storing the chip number for the nonvolatile memory to be used in asembly of the meter and the seed number in a data center.

7. The method recited in claim 5, including the step of:

displaying proper entry of the received information into the meter.

8. The method recited in claim 5, including the step of:

directly entering the information received from the data center into the meter.

9. The method recited in claim 5, including the step of:

communicating to the data center the rejection of the received information in the absence of it being properly enterable into the meter.

10. The method recited in claim 5 including the step of:

rejecting the meter if the received information is not properly enterable into the meter.

11. An electronic postage meter into which a serial number is enterable upon completion of assembly of the electronic postage meter within a case to which the serial number had been assigned, the electronic postage meter being communicatingly connectable to a data center, comprising:

a nonvolatile memory into which a chip number is entered;

means for communicating the serial number of the electronic postage meter and the chip number of the nonvolatile memory to the data center;

means adapted for receiving from the data center reset information based upon the chip number and serial number of the electronic postage meter;

means for entering the received reset information into the meter;

means for writing the serial number of the electronic postage meter into the nonvolatile memory if the received reset information is properly enterable into the meter and

means for preventing further writing into the nonvolatile memory where the serial number is written once said means for writing the serial number has written the serial number in the nonvolatile memory.

12. The electronic postage meter of claim 11, wherein:

said means adapted for receiving information includes a data link.

13. The electronic postage meter of claim 11, wherein:

said means adapted for receiving information includes a telephone.

14. The electronic postage meter of claim 11, wherein:

said entering means includes a keyboard.

15. The electronic postage meter of claim 11, wherein:

said entering means includes a data link for directly entering the received information into the meter.
