摘要:
According to an embodiment, an IC card includes a communication section and a control section. The control section divides data which is transmitted to the external device. Moreover, the control section transmits a divided data portion to which an error detection code is given, to the external device through the communication section intermittently so as to make a predetermined non-transmission period. Moreover, the control section detects an error notice showing a failure in receiving divided data from the external device in the predetermined period. Furthermore, the control section retransmits the divided data portion to which the error detection code is given transmitted last after detecting the error notice.

An authentication device with photosensitive input keys, a photosensitive input key consisting of a key switch paired with a photosensor disposed sufficiently close to said key switch that at each keystroke the user's finger will at first obstruct and then allow light to said photosensor. By correlating contacts closure-opening with variations in the level of light reaching said photosensor, a keystroke can hence be detected in a very reliable way. The very same photosensor is also used for transferring optically encoded data to the authentication device.

La carte bancaire (2), en particulier carte de crédit ou de débit, permet d'effectuer des transactions en ligne. Cette carte bancaire est associée à au moins un compte bancaire et présente sur l'une de ses deux faces un code de sécurité associé à ce compte bancaire. La carte bancaire comprend en outre un affichage électronique (16) agencé pour afficher le code de sécurité, en particulier un code à trois chiffres (CVV), et un circuit électronique (18,20,22) agencé pour varier ce code de sécurité au cours du temps. Dans un mode de réalisation particulier, le code de sécurité est changé à la fin de périodes de durée constante qui sont déterminées par le circuit électronique de la carte bancaire, laquelle comprend une base de temps à cet effet. Le système de traitement informatique du service bancaire, qui traite le paiement des transactions en ligne aux vendeurs par débit du compte lié à la carte bancaire, comprend aussi des moyens permettant de définir des périodes correspondantes et de déterminer un ou des code(s) valable(s), pour chacune de ces périodes correspondantes et pour chaque carte bancaire donnée, en fonction d'un paramètre temporel sélectionné par ce système de traitement informatique.

Implementations of a portable consumer transaction device include a portable consumer transaction payment card having a power supply, memory to store information and instructions, where the information includes an identifier for an account issued to a card holder for the use of the portable consumer transaction payment card to conduct a transaction on the account with a merchant, an active magnetic strip encoding the account, an input device to put the information in the memory, and a computing device to execute instructions to control access by the card holder to use the portable consumer transaction payment card to conduct the transaction on the account at a Point of Service terminal with the merchant. The card can display an associated current account balance which can be written to the memory after a transaction has occurred.
摘要:
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.

The present invention proposes a security information interaction system, device and method based on the extended parameter set. Said security information interaction system based on the extended parameter set comprises a security information interaction device and a security information interaction terminal, wherein said security information interaction device may execute the operations related to the transfer of a resource by means of performing the security information interaction with said security information interaction terminal via a communication interface based on one of a primary parameter set and the extended parameter set. The security information interaction system, device and method based on the extended parameter set disclosed in the present invention may realize the transfer operations of multiple kinds of resource having different attributes, the cost is lower, and the flexible configuration and extension can be realized according to the requirements.
摘要:
The present disclosure is directed to a system and method for amplifying Radio Frequency (RF) signals. In some implementations, a system includes a first interface, a second interface, secure memory, a user-interface module, a processing module, and am amplification module. The first interface connects to a microSD slot of a mobile host device. The second interface includes an internal antenna for wirelessly communicating with retail terminals. The secure memory stores user credentials and a payment application used to execute financial transactions with the retail terminals. The processing module executes the payment application using the user credentials in response to at least a transaction request received by the RF module and transmits at least one transaction response to the retail terminal based, at least in part, on the executed payment application. The amplification module connected to a lead of the antenna and is configured to amplify at least received RF signals.
