Abstract
Abstract Methods enabling the use of an office printer connected to a microcomputer in order to print legitimate postal marks. It uses a cartridge of special fonts in which there are stored the franking marks according to the standards laid down for the printer. A known security component is provided, on the one hand to protect access to the memory contained in the cartridge and, on the other hand, to perform the computation, for each printing of a franking mark, of a security mark that contains encrypted information elements that are readable by the postal authority, enabling the franking mark to be authenticated. It provides for the elimination of specific franking machines and limits the handling operations to the handling of a small-sized cartridge.

Claim 2
Independent Claim
121 words

Claim 6
Dependent Claim
26 words
A method according to claim 1, wherein the security mark is a directly readable bar code whose alphanumeric contents represent security information in an encrypted form.
Claim 7
Dependent Claim
52 words
A method according to claim 1, further comprising the steps of re-determining the security mark; and then reloading the franking and security marks into the printer; and reprinting the security and franking marks a plurality of times; wherein the re-determining and reloading steps are performed before each performance of the reprinting step.
Claim 8
Dependent Claim
57 words
A method according to claim 6, wherein printer control signals are made to transit via the detachable cartridge to enable the detachable cartridge to intercept the control signals for the printing of a franking mark and to cause the control signals to be preceded by a control signal for the reloading of the font into the printer.
Claim 9
Dependent Claim
26 words
A method according to claim 7, wherein the transit of the control signals is electrically and logically transparent to a device which transmits the control signals.
Claim 10
Dependent Claim
134 words
A detachable cartridge for a primer, the detachable cartridge comprising a memory which stores a franking mark and a security mark, the security mark enabling the franking mark to be authenticated, the memory also storing fixed and variable data elements used for determining the security mark, and the franking mark and the security mark being in the form of graphic elements translated into the format of the characters of the printer, a security circuit which secures the access to the memory and which determines the security mark, the security mark being determined automatically and in a secure manner based on the fixed and variable data elements, a connector which is adapted for connecting the detachable cartridge to the printer, and an interface which connects the connector to the memory and to the security circuit.
Claim 11
Dependent Claim
