Abstract: An electronic system for payment via a telecommunications network between firstly a vendor having a server suitable for implementing a secure protocol for payment by smart card, and secondly a client having navigation and electronic payment means suitable for making a payment to said vendor using client software for handling payment that includes the secure payment protocol. The client software for handling payment is installed on a payment server on the telecommunications network. The system comprises, at the client end, navigation means, electronic payment means constituted by a mobile terminal connected to the network and including a reader for reading payment smart cards, and means for redirecting messages suitable for transmitting at least the call number of the mobile terminal to the payment server.

Abstract: An authentication server automatically selects one of plural authentications identified by authentication identifiers to authorize access by a user to a service dispensed by a service server of a provider identified by a provider identifier via a communication network. The server includes a module for selecting an authentication identifier in a memory as a function of the provider identifier and the type of the terminal and/or the network type of the communication network, and a module for authenticating the user by launching an authentication process associated with the authentication identifier.

Abstract: The present invention relates to a method of issuing a printed ticket coming from a thermal printer, which printer comprises in a structure, a print head and a capstan for driving the ticket, a ticket travel guide being provided in the structure downstream from the print members, the method consisting in: a) storing in a memory of the printer the data for printing on the ticket; b) causing the ticket to advance by a determined amount so as to enable the user to grasp the ticket manually at the end of the guide; c) within a determined length of time from the end of step b), detecting the user applying a traction force to the ticket; and d) in response to said detection, simultaneously causing printing to take place on the ticket and the ticket to be ejected towards the user.
