    • Embodiments of the invention provide a portable consumer device configured to store dynamic authentication data in memory. The portable consumer device also includes an interface for transmitting data to and receiving power from an external device. The dynamic authentication data is read from the memory by a read-write device located on the portable consumer device. The authentication data is updated and the updated data may be written into memory using the read-write device. In some embodiments, an authentication value read from the memory may be used to generate another authentication value based on an algorithm. The portable consumer device is further configured to transmit authentication data to an external device. The process of reading, updating, generating, transmitting, and rewriting the authentication data may occur each time external power is provided to the portable consumer device via the interface. The power for operating the components of the portable consumer device may be drawn exclusively from the power received from the external device (i.e., the external power). In some embodiments, a portion of the external power may be temporarily stored on an energy storage means of the portable consumer device.
    • 本发明的实施例提供了被配置为将动态认证数据存储在存储器中的便携式消费者设备。 便携式消费设备还包括用于向外部设备发送数据并从外部设备接收电力的接口。 通过位于便携式消费设备上的读写装置从存储器读取动态认证数据。 更新认证数据,并且可以使用读写装置将更新的数据写入存储器。 在一些实施例中,从存储器读取的认证值可以用于基于算法生成另一认证值。 便携式消费者设备还被配置为将认证数据发送到外部设备。 每当通过接口向便携式消费者设备提供外部电力时,可以发生读取,更新,生成,发送和重写认证数据的过程。 用于操作便携式消费者设备的组件的功率可以仅从从外部设备接收的功率(即外部功率)来绘制。 在一些实施例中,外部功率的一部分可以临时存储在便携式消费设备的能量存储装置上。

    • Embodiments of the present invention are directed to systems, apparatuses and methods for using a mobile device with an accelerometer to gain access into a secured or restricted area. A first device and a second device interact by making physical contact with each other thereby generating interaction data that is representative of the physical interaction between the first and second device. The first and second device may be mobile phones. The second device may be a point of sale terminal, access point device, or any other stationary (i.e., in a fixed position) device positioned at a line, door, gate, or entrance. A server computer determines, based on interaction data, that the first device and the second device made physical contact. After determining that the first device and the second device made contact, communications may be initiated between the devices. Communications may relate an access transaction comprising an exchange of information, such as credentials, between a prospective entrant (operating the first device) and a gatekeeper (operating the second device) to verify that the prospective entrant is permitted or is not permitted access to a particular area that is secured or restricted by the gatekeeper. Other embodiments are direct to confirmation transactions. Access transaction and confirmation transactions may be combined with a financial transaction using a payment processing network.
    • 本发明的实施例针对用于使用具有加速度计的移动设备来访问安全或受限制的区域的系统,设备和方法。 第一设备和第二设备通过彼此物理接触来交互,从而生成表示第一和第二设备之间的物理交互的交互数据。 第一和第二设备可以是移动电话。 第二设备可以是销售点终端,接入点设备,或位于线路,门,入口或入口处的任何其他静止(即处于固定位置)设备。 服务器计算机基于交互数据确定第一设备和第二设备进行了物理接触。 在确定第一设备和第二设备联系之后,可以在设备之间发起通信。 通信可以涉及在预期进入者(操作第一设备)和关守(操作第二设备)之间交换信息(诸如凭证)的访问交易,以验证预期参赛者被允许或不被允许访问 由看门人保护或限制的特定区域。 其他实施例直接涉及确认交易。 访问交易和确认交易可以与使用支付处理网络的金融交易相结合。
