## Abstract

A technique for reconfiguring in the field postage meters having a set of features that may be selectively enabled or disabled by software. The technique provides security so that the meter company will always have a correct record of the configuration of the meter in the field. A technique is provided for reconfiguring in the field of external devices in communication with postage meters, the external devices having an external device feature set that may be selectively enabled or disabled by software. A technique for securely adding postage to a remote setting postage meter without the remote setting code is also provided. A technique for detecting the entry of an invalid code for remote setting the meter a predetermined number at times is also provided. Once detected, a security lock flag stored in memory is set which prevents the meter from being reset until the flag is cleared in a separate procedure.

## Claims

### Claim 1

An electronic postage meter having a postage amount that can be remotely set by the entry of a remote setting code, the meter comprising:
(a) detection means for detecting the entry of an invalid remote setting code a predetermined consecutive number of times;
(b) prevention means, responsive to the detection means, for selectively preventing the postage amount from being remotely set upon the entry of an invalid remote setting code the predetermined consecutive number of times;
(c) generating means for generating a first meter code and a second meter code, said generating means firmly engaged with the meter;
(d) display means, coupled to the generating means, for displaying the first meter code;
(e) entry means for entering a non-meter code different from said remote setting code, said non-meter code generated at a data center computer by receiving said first meter code;
(f) comparison means, coupled to the generating means and the entry means, for comparing the second meter and non-meter codes; and
(g) enabling means, responsive to the comparison means, for disabling the prevention means upon the second meter and non-meter codes being equal so as to reenable entry of said remote setting code.

### Claim 2

An electronic postage meter having memory capable of being modified by entry of a remote setting code, the meter comprising:
(a) detection means for detecting the entry of an invalid remote setting code a predetermined number of times;
(b) prevention means, responsive to the detection means, for selectively preventing the modification of memory upon the entry of an invalid remote setting code the predetermined number of times;
(c) generating means for generating a display code and an internal meter code in said postage meter upon activation of said prevention means;
(d) display means, coupled to said generating means, for displaying said display code;
(e) entry means for entering a data center code different from said remote setting code, said data center code generated at a data center computer, said data center code retrievable from the data center computer by a user communicating said display code and said valid remote setting code to said data center computer;
(f) comparison means, coupled to the generating means and the entry means, for comparing the internal meter and data center codes; and
(g) enabling means, responsive to the comparison means, for disabling the prevention means upon the internal meter and data center codes being equal, said enabling means reenabling entry of a valid remote setting code.

### Claim 3 (depends on 2)

The electronic postage meter of claim 2 further comprises second generating means for generating a second display code, said second generating means coupled to said display means.

### Claim 4

An electronic postage meter having a postage amount that can be remotely set by entry of a remote setting code, the meter comprising:
(a) detection means for detecting the entry of an invalid remote setting code a predetermined number of times;
(b) prevention means, responsive to the detection means for selectively preventing the postage amount from being remotely set upon the entry of an invalid remote setting code the predetermined number of times;
(c) generating means for generating an internal meter code in said postage meter upon activation of said prevention means;
(d) entry means for entering a data center code different from said remote setting code, said data center code generated at a data center computer, said data center code retrievable from the data center computer by a user communicating information indicating that said user is authorized to have the remote setting code;
(e) comparison means coupled to the generating means and the entry means for comparing the internal meter and data center codes; and
(f) enabling means responsive to the comparing means, for disabling the prevention means upon the internal meter and data center codes being equal so as to enable entry of said remote setting code.

### Claim 5 (depends on 4)

The electronic postage meter of claim 4 further comprising:
(a) second generating means for generating a display code; and
(b) display means, coupled to the second generating means, for displaying the display code.

### Claim 6 (depends on 4)

The electronic postage meter of claim 4 further comprising a print means for printing postage not greater than the postage amount.

### Claim 7 (depends on 6)

The electronic postage meter of claim 6 wherein the prevention means further prevents the print means from printing postage upon the entry of an invalid remote setting code the predetermined number of times.

### Claim 8 (depends on 4)

The electronic postage meter of claim 4 further comprising enabling means for enabling the postage amount to be remotely set upon the entry of a second non-meter code.
