从文件中读取数据的方法、阅读器、文件以及电子系统
摘要：
本发明涉及一种借助阅读器(102)从文件(104)中读取数据(120)的方法。该方法中，通过阅读器形成传送器(110)的初级端；文件具有存储数据的电子存储器(118)、从存储器中读取数据的处理器工具(114)以及至少一个由处理器工具所控制的电子消耗设备(128、130、132)；通过文件形成传送器的次级端；处理器工具和至少一个电子消耗设备耦合到次级端以提供能量；该方法包括如下步骤：在初级端施加初级端电压(U)，以便在次级端耦合进能量；通过处理器工具控制至少一个电子消耗设备，从而形成随时间而变化的次级端负荷，初级端以此被调制；通过阅读器，对初级端的调制进行评估，以输出根据评估结果而决定是否读取数据的读取命令。
摘要（英）：

The invention relates to a method for reading data (120) from a document (104) using a reader (102), wherein the reader forms the primary side of a transformer (110), wherein the document has an electronic memory (118) for storing the data, processor means (114) for reading the data from the memory and at least one electrical load (128, 130, 132) which can be actuated by the processor means, wherein the document forms the secondary side of the transformer, and wherein the processor means and the at least one load are coupled to the secondary side for the purpose of supplying power, having the following steps: a primary-side voltage (U) is applied to the primary side for the purpose of injecting power into the secondary side, the at least one load is actuated by the processor means, as a result of which a time-variant secondary-side load is formed which prompts the primary-side voltage to undergo modulation, the modulation of the primary-side voltage is evaluated by the reader in order to execute read access for the purpose of reading the data on the basis of a result of the evaluation.
