Abstract: The payment card includes at least one authentication cryptogram on one side of the card. The authentication cryptogram being unique and belonging to the payment card, is affixed to the payment card and identifies the payment card by optical recognition. The optical recognition identifier is linked to a bank account to which the payment card is linked. The method for authenticating the payment card and the bearer of the payment card is performed for a secure operation relating to personal data of the bearer of the payment card. Finally, the invention relates to a use of the authentication method to make a remote payment using the payment card.

Abstract: The method secures data of a bank card linked to a bank account. The data is static and includes the number of the card, the identification data of the holder of the card, the expiration date of the card, and a cryptogram. The bank card number and cryptogram include multiple digits and/or letters. The method includes inscribing only partially secure data on the card in such a manner that the data is concealed and never visible on the card. The concealed data is multiple digits and/or letters of the number of the card and/or at least an identification datum of the holder and/or at least one element of the expiration date and/or at least one digit and/or letter of the cryptogram. The method includes transmitting to the only cardholder a means for disclosing the concealed data.

Abstract: The invention relates to a self-lighting device for a cigarette, comprising a primary chemical material (7) to be placed at the lighting end (4) of the cigarette (1); and a secondary chemical material (8) that is incompatible with the primary material (7), said primary and secondary materials being inflammable when they come into contact with each other. The device is characterized in that the secondary material (8) is arranged in a receptacle (9) designed to fit over the lighting end (4) of the cigarette (1), bringing the secondary material into contact with the primary material (7).

Abstract: The invention relates to a device for self-lighting of a cigarette (1), comprising a primary chemical material and a secondary chemical material, said chemical materials being incompatible and generating sufficient thermal energy to light the end (4) of said cigarette when they are in contact with one another, —the primary chemical material is placed in a capsule (70) intended to be fixed at the end to be lit (4) of the cigarette (1), —the secondary chemical material is disposed in a receptacle (80) designed to be positioned at the end to be lit (4) of the cigarette (1) in an arrangement that allows said secondary material to be brought into contact with the primary material, characterized in that: —the capsule (70) is made of an airtight and moisture-tight combustible material, said capsule having at least one puncturing zone, —the receptacle (80) incorporates a sealed container containing the secondary chemical material, said reservoir comprising a pointed end piece (82) the rigidity of which is sufficient

Abstract: The invention relates to a cigarette provided with a self-lighting device comprising: a primary chemical material (7) placed at the lighting end (4) of the cigarette (1), and a secondary chemical material (8) that is incompatible with the primary material (7), said primary and secondary materials being inflammable when they are in contact with each other. The secondary material (8) is contained in a receptacle (9) initially arranged at one of the ends of the cigarette, in an arrangement preventing said secondary material and said primary material (7) from coming into contact, and said receptacle is removable and configured in such a way as to be positioned against the end (4) to be lit, in an arrangement enabling the secondary material (8) to be brought into contact with the primary material (7), the receptacle being initially fixed to the end (5) opposing the end to be lit (4).
