Claim 3

Dependent Claim 22 words

A portable radio pager according to claim 1, in which the additional code is an internal code contained in the memory (8).

Claim 4

Dependent Claim 146 words

A portable radio pager according to claim 1, further including an interface (41) enabling it to dialog with an external smart card (40), and in which the CPU (7) is further designed: to send an initial code that is a function of the primary code to the smart card (40) via the interface (41); after the secondary code has been input with the keypad (3), to send the secondary code to the smart card (40) by means of the interface (41); to receive the above-mentioned additional code, referred to as a "resultant" code, from the smart card (40) as defined by the smart card (40) as a function of the initial code sent thereto, of an internal code that it contains, and of the secondary code; and to define the encoded sound signal as a function of the resultant code received from the smart card (40).

Claim 5

Dependent Claim 220 words

A method of remotely identifying a person by using a portable radio pager (1) according to claim 1 which receives radio messages from at least one transmitter station (20), the method comprising the following steps: a) making telephone contact with the user of the pager (1) by means of a telephone set (32); b) causing the user of the pager (1) to communicate an identification code specific to the user; c) causing the transmitter station (20) to transmit at least one certification primary code addressed to the pager (1); d) causing the user of said pager to enter a secondary code by means of the keypad (3) of the pager; e) causing the sound signal emitter (9) of the pager (1) to emit the encoded sound signal which is defined by the CPU (7) of the pager as a function of the primary code, of the internal code, and of the secondary code, the sound signal emitter (9) being located at that time in the vicinity of a microphone (32b) belonging to the telephone set (32); f) determining the encoded sound signal which ought to have been emitted as a function of the primary code and of the secondary code; g) verifying whether a predetermined relationship exists between the identification code, the certification primary code, and the encoded sound signal.

Claim 6

Dependent Claim 80 words

A method according to claim 4, in which the identification code specific to the user of the pager (1) is included in the memory (8) of the pager, and in which step b) consists in causing the sound signal emitter (9) of the pager (1) to emit a run of individual sound signals representative of the identification code, the signal emitter (9) being located at that time in the vicinity of a microphone (32b) belonging to the telephone set (32).

Claim 7

Dependent Claim 276 words

A method of remotely identifying a person using a portable radio pager (1) according to claim 3, which receives radio messages from at least one transmitter station (20), the method comprising the following steps: a') making telephone contact with the user of the pager (1) by means of a telephone set (32); b') causing the user of the pager (1) to communicate at least one identification code specific to the smart card (40) of the user; c') causing the transmitter station (20) to transmit at least one certification primary code addressed to the pager (1); d') causing the initial code which is a function of the certification primary code to be sent to the smart card (40) via the interface (41); e') causing the user of said pager to enter a secondary code by means of the keypad (3) of the pager, and causing said secondary code to be sent to the smart card (40) via the interface (41); f') causing the smart card (40) to communicate a resultant code to the CPU (7), which resultant code is a function of the initial code, of the secondary code, and of the internal code contained in said smart card; g') causing the CPU (7) to define the encoded sound signal corresponding to the resultant code; h') causing said encoded sound signal to be emitted by the sound signal emitter (9) of the pager (1), the sound signal emitter (9) being located at that time in the vicinity of a microphone (32b) belonging to the telephone set (32); and i') verifying whether a predetermined relationship exists between the identification code, the primary code, and the encoded sound signal.

Claim 8

Dependent Claim 87 words

A method according to claim 6, in which the identification code is stored in the smart card (40), and in which step b') consists in causing the CPU (7) to read the identification code of the smart card (40) via the interface (41), and in causing the sound signal emitter (9) to emit a run of individual sound signals representative of the identification code, the sound signal emitter (9) being located at that time in the vicinity of a microphone (32b) belonging to the telephone set (32).

Claim 9

Independent Claim 46 words

A method according to any one of claims 4 to 7, including a subsequent step which consists in authorizing a remote payment operation only if it is verified that the predetermined relationship exists between the identification code, the certification primary code, and the encoded sound signal.
