Abstract: A card configured to output an magnetic field on or at a surface thereof, the card comprising an elongated magnetically conducting material on or at the surface of the card, the magnetically conducting material having a first and a second guide ends, and a field generator positioned so as to feed a magnetic field into the magnetically conducting material. The magnetically conducting material is positioned at the position where the reading head travels and forms a return path for the field generated by the field generator, whereby field from the generator is fed to the reading head via the magnetically conducting material.

Abstract: A fingerprint reader comprising a fingerprint sensor adapted to output information relating to a fingerprint of a finger engaging a sensitive surface the sensor, and a stiff element comprising an indentation/cavity or through-hole, the sensor being positioned in the indentation/cavity/through-hole so that the sensitive surface is exposed to the surroundings. The stiff element will prevent breaking of the reader. Also, the stiff element may have one or more electrically conducting surface parts positioned adjacently to the sensitive surface of the sensor and being adapted to be contacted by a finger also contacting the sensor, so that the stiff element forms part of the reader.

Abstract: An RFID tag comprising a coil and an RFID chip having two inputs/outputs, each input/output being connected to the coil. The tag further comprises an electrical circuit connected to the inputs/outputs, the circuit being adapted to operate in one of two modes, one mode outputting substantially no signal whereby the RFID chip is allowed to operate and a second mode being a mode wherein a signal is output so that the operation of the RFID-chip is interrupted. Alternatively, the circuit may have a lower operating voltage than the RFID-chip and may thus starve the RFID-chip and prevent its operation when desired.

Abstract: A card for presenting visual information while being waved. The card is flexible and has a sensor detecting or quantifying the bending of the card. The card has, preferably at an edge thereof, light emitters for presenting the information. A controller determines the position of the edge and forwards information so that a user watching the edge sees an emulated 2D information provider.

Abstract: A portable card, such as a credit card, having therein electronics, such as a processor, and a deformable switching element or sensor, where the deformation or bending of the sensor/switch is determined and used for controlling the electronics. In one aspect, bending of a piezo element provides power for bringing a processor out of a sleep mode.

Abstract: A transaction card comprising a processor connected to at least one coil, the processor being adapted to: receive a signal output by the coil caused by a magnetic field acting on the coil; derive, from the signal, information relating to the card; store the information; and subsequently transmit, to the surroundings, the information by transmitting a corresponding signal to the coil. The transaction card may be adapted to remember the positions at which the information was store to the card, and to output the information at the same positions when information is read from the card. A method for storing and transmitting information to the transaction card.

Abstract: The present invention relates to a credit card comprising a card body, which comprises fingerprint reading means providing fingerprint signals representative of at least one fingerprint from a card user, when at least one finger of said user is pressed against said fingerprint reading means. Said card body further comprises data carrier means holding at least card owner fingerprint data and secured data, and fingerprint authentication means for activating said secured data. The card body further comprises an electrical power supply delivering electrical current to at least said fingerprint reading means. Accordingly, there is no need for an external electrical power supply, and thus the existing standard card reading systems, such as ID-card readers, money transfer machines such as ATM's and the like may be used in conjunction with said credit card. Thus, investments into new standard reader systems are not necessary in order to improve the security of the secured data carried by the credit card.
