    • A self-service checkout terminal includes a scanner and a weight scale. The customer passes each item past the scanner to identify the item and obtain weight data for that item from a centralized database, including a mean weight and a standard deviation. An error value is calculated from the measured weight of each item and the weight data. The error value of all items scanned during the common transaction are summed to produce an accumulated error for the particular weight scale during that transaction. This accumulated error is compared to a threshold value to determine whether a fault condition exists at the weight scale.
    • 自助结帐终端包括扫描仪和称重秤。 客户将每个物品通过扫描仪,以识别物品,并从集中数据库中获得该物品的重量数据,包括平均重量和标准偏差。 根据每个项目的测量重量和重量数据计算误差值。 在通用事务期间扫描的所有项目的错误值相加,以在该事务期间产生特定权重量表的累积误差。 将该累计误差与阈值进行比较,以确定在重量级别是否存在故障条件。

    • A method is provided for personalizing security conditions for each customer using a self-service checkout terminal to conduct a transaction on the terminal. A trust level is assigned to each customer based on a selection of factors, which may include personal information provided by the customer, factors independent of the customer, such as information specific to the particular merchant, and the customer's history in using the checkout terminal or other facilities of the merchant. The manner in which the transaction progresses for the customer is determined as a function of the customer's trust level. In one example, the weight tolerance applied to products weighed by the customer may be widened or narrowed in relation to the customer's trust level.
    • 提供了一种用于使用自助服务检验终端对每个客户的安全条件进行个性化的方法,以在终端上进行交易。 基于选择的因素,信任级别被分配给每个客户,这些因素可以包括由客户提供的个人信息,独立于客户的因素,例如特定商家特有的信息,以及客户使用结账终端的历史 商家的其他设施。 客户的交易进展方式根据客户的信任级别确定。 在一个示例中,应用于由客户称重的产品的重量公差可以相对于客户的信任级别来扩大或缩小。
