Abstract
The invention relates to the design of card readers for cards equipped with memory. Such cards, and also the data stored in the memory of such cards, are generally utilized to produce and/or maintain operating states of technical devices. It is also known that the user personally can store data in certain areas of the memory. However, as the memory design and usage has been standardized for the most part and the memory capacity reserved for use by the user is relatively small, the memory capacity reserved for the user can only be increased by providing the device with additional cards equipped with memory. However, as all cards used in a device to supply the full functionality must operate together in a prescribed manner, it is the task of the invention to specify a card reader that organizes this operation. To accomplish this, it is specified that a monitoring deviceor a closing deviceis present that prevents the insertion of a second cardwhen there is a first cardinserted in the first slot, or that ensures, when there are two cardsin the slotsthat the first cardis removed from its corresponding slotbefore second cardis removed.
