Abstract: In order further to minimise the power consumption when registering electronic tickets, a method is proposed in which the bidirectional communication in a higher frequency band is initiated when the tickets have received a wake-up signal in a lower frequency band via a further highly sensitive receive module. This so-called space wake-up precedes the entry stamping which takes place in accordance with the prior art. Entry stamping means: transferring and storing a wake-up telegram containing an identity of the detection space, said wake-up telegram being received by a first receive module which is contained in a ticket.

Abstract: In an entrance zone, or a prompting zone, a second transmitting receiving module located on the ticketed is activated. A communication can thus be established between the ticket and a second transmitting receiving unit which is assigned to a detection zone. During this communication, the presence of the ticket is determined and registered in a defined time slot pattern. This guarantees a reliable and fraud proof detection of tickets. The method and system for registering tickets is used in public transport, at exhibitions and in secured areas.

Abstract: Electronic tickets are triggered by a trigger message, out of a standby state, for the determination of used capacity. In order to further reduce energy requirements, or to increase the autonomy of the tickets, a trigger message recognition and selection is disclosed, whereby firstly a trigger message is detected in a receiver and, subsequently, when information contained in a detected tigger message is destined for the relevant ticket, a processor module is activated by means of a switch. In a preferred embodiment, the activation is a multi-stage form, in which a digital filter is arranged between the receiver and processor module which can also be activated by a switch. The switch for activating the process module may be operated by the digital filter.

Abstract: When using a magnetic alternating field to prompt portable electronic tickets, such as smart cards, it is important that the prompting is effected reliably and independent of the position thereof. In order to generate an essentially isotropic magnetic alternating field over a set time interval, one embodiment of the invention involves the use of an antenna array comprising two or three frame antennas. A switching unit supplies, in a sequentially alternating manner, a unit of information to each of the frame antennas so that a quasi-isotropic magnetic alternating field, which is considered over the period of time, is radiated by said frame antennas. This results in reliably prompting tickets that are located in the surrounding area of the antenna arrays.

Abstract: Electronic tickets passing through a passage area and arriving in a detection area receive a first information unit including the identity of the detection area, whereby a second transmitter/receiver module located on the ticket is activated. At the beginning of the provision of a service, for instance, after the departure of a train, the tickets receive a second information unit that likewise includes the identity of the detection area, wherein at least the identity of the detection area is then stored as presence information if it matches the identity contained in the first information unit. If necessary, this method step is repeated. When the tickets leave the detection area through the passage area, they receive once again a first information unit and transmit a third information unit containing the stored presence information along with the identity of the ticket to a second transmitter/receiver unit, which registers the presence of the corresponding ticket.

Abstract: When registering electronic tickets by means of a transmitter/receiver unit located in a railway carriage, for charging purposes data is created in a remote computer system which yields a movement profile for the persons using such tickets. For the anonymous prepaid registration of tickets it is proposed that a shadow account be maintained on the tickets to which postings are made using provisional tariff units contained in transmitted information units. In the remote computer system, a booking or posting is made to an account assigned to the respective ticket, using definitive tariff units contained in tariff tables. When a prepayment is made or at certain points in time the balance of the shadow account is synchronized with the balance on the remote computer system.

Abstract: The invention relates to a multi-layered carrier element for reducing interference with an antenna comprising at least one coil. In addition to the layer, the antenna comprises a shield which is placed along at least one extension of the antenna and split at a certain point. The shield is electrically connected to a reference point which is located on the carrier element and is preferably electrically connected to the ground layer. The shield reduces interference such as that caused by a hand or by a nearby metallic object.
