    • Embodiments of the present invention are directed to systems, apparatuses and methods for using a first device with an accelerometer to transfer data by making contact with a second device with an accelerometer, thereby generating interaction data that is representative of the physical contact between the mobile device and the second device. The first device may be a mobile phone. The second device may be a mobile phone or a stationary kiosk or terminal. A first device with an accelerometer physically contacts the second device. Each of the first and second devices generate interaction data (e.g., accelerometer, location, time data, etc.) representative of the physical interaction between the first and second device. A server computer determines, based on interaction data, that the first device and the second device physically contact each other. After determining that the mobile device and the second device made contact, communications may be initiated between the devices. Communications may include customer-provided information (e.g., shopping lists) and merchant-provided information (e.g., items in stock or on sale from the consumer's shopping list). In some embodiments, at least two independent interactions between three devices transfer data from a first computing device to a second computing device, after each of the first and second computing devices independently interacts with a mobile device.
    • 本发明的实施例涉及用于使用具有加速度计的第一设备通过与加速度计接触第二设备来传送数据的系统,设备和方法,从而生成表示移动设备之间的物理接触的交互数据 和第二设备。 第一设备可以是移动电话。 第二设备可以是移动电话或固定式售货亭或终端。 具有加速度计的第一设备物理地接触第二设备。 第一和第二设备中的每一个产生表示第一和第二设备之间的物理交互的交互数据(例如,加速度计,位置,时间数据等)。 服务器计算机基于交互数据确定第一设备和第二设备物理上彼此接触。 在确定移动设备和第二设备联系之后,可以在设备之间发起通信。 通信可以包括客户提供的信息(例如,购物清单)和商家提供的信息(例如,来自消费者购物清单的库存或销售的商品)。 在一些实施例中,在第一和第二计算设备中的每一个独立地与移动设备交互之后,三个设备之间的至少两个独立交互将数据从第一计算设备传送到第二计算设备。

    • Methods, systems, and apparatus for efficiently authenticating a document (e.g. a credit card) having a magnetic stripe are provided. The magnetic field at different points of the magnetic stripe are measured, e.g., by a checkout scanner to create a magnetic signature. Digital samples of the measurements may be transformed into coefficients of continuous basis functions, e.g., a Fourier transform. These coefficients are then compared to reference values (e.g. corresponding coefficients) to produce a measure of the authenticity of the document. The number of coefficients used can advantageously be smaller than the number of digital samples without compromising accuracy, thus using less bandwidth between a scanner and an authentication entity.
    • 提供了用于有效地认证具有磁条的文档(例如,信用卡)的方法,系统和装置。 例如通过检验扫描仪来测量磁条的不同点处的磁场以产生磁性签名。 测量的数字样本可以被变换为连续基函数的系数,例如傅里叶变换。 然后将这些系数与参考值(例如相应的系数)进行比较以产生文档真实性的量度。 所使用的系数的数量可以有利地小于数字样本的数量,而不损害精度,因此在扫描仪和认证实体之间使用较少的带宽。
