     DETAILED DESCRIPTION OF THE INVENTION 
       [0030]    In order that those skilled in the art can further understand the present invention, a description will be provided in the following in details. However, these descriptions and the appended drawings are only used to cause those skilled in the art to understand the objects, features, and characteristics of the present invention, but not to be used to confine the scope and spirit of the present invention defined in the appended claims. 
         [0031]    Referring to  FIG. 3 , the first embodiment of the interactive card according to the present invention is illustrated. The present invention has the following elements. 
         [0032]    A base sheet  1  is a thin plate. One side of the base sheet  1  is printed with messages. Another side of the base sheet  1  has a shaft  11  for engaging other elements (see  FIG. 1A ). The shaft  11  may be formed by punching the base sheet  1  or is installed to the base sheet  1  by adhering or gluing or suturing. 
         [0033]    A multi-layer rotary disk has for example four layers including a first layer  12 , a second layer  14 , a third layer  16  and a fourth layer  18 . In this embodiment, the multi-layer rotary disk has an approximate round shape. Each layer has an axial hole  20 . A diameter of the axial hole  20  is slightly larger than a diameter of the shaft  11  for receiving the shaft  11  corresponding to the layers  12 ,  14 ,  16  and  18  so that the layers of the mobile device are rotatable with respect to the shaft  11  (see  FIGS. 2A to 2D ). 
         [0034]    In this embodiment, the first layer  12  and third layer  16  of the multi-layer rotary disk are window layers. Each window layer has a window  22 . The second layer  14  and fourth layer  18  are data layers. The surface of the data layer is printed with data to be displayed. By the window  22  of the window layer, the data on the data layer below the window  22  can be seen. In this embodiment, the indications  111  on the second layer  14  and fourth layer  18  are numbers (such as 0, 1, 2, 3, 4, 5, . . . ) and English alphas (from A to Z)j [X]. The indications  111  are arranged around the axial hole  20 . 
         [0035]    In an optimum arrangement, an area of the layer at an upper side is not greater than that of a layer at a lower side so that the operation can be performed easily. 
         [0036]    A cap  3  can be engaged to the shaft  11  or is adhered to or glue to or sutured to the shaft  11 . The area of the cap  3  is greater than that of the shaft  11  for preventing the layers to release from the shaft  11  (referring to  FIG. 1B ). 
         [0037]    Referring to  FIG. 3A , in assembly, each layers  12 ,  14 ,  16  and  18  are engaged to the shaft  11  extended from the base sheet  1  by the shaft  11  inserting into the axial holes  20  of the layers of the multi-layer rotary disk. Finally, the cap  3  is installed at a top end of the shaft  11 . The area of the cap  3  is greater than that of the shaft  11  for preventing the layers to release from the shaft  11 . 
         [0038]    The present invention has wide applications, such as general used cards, for example name cards, or bookmarkers, labels, tickers, memos, furthermore, the book of itself etc. The indications  111  on the layers of the multi-layer rotary disk may be numbers, symbols, alphas, words, etc. for indicting chapters, pages, paragraphs, sections, of a book, or dates for something to be recorded. 
         [0039]    The present invention can be objects, such as conventional bookmarkers, name cards, memos of marriage, IC cards, book of itself, etc. so as to increase the utilities of these objects and thus the cards will keep the attention of the owners (referring to  FIG. 3B ). 
         [0040]    Referring to  FIG. 3A , the application of the present invention will be described with reference to the drawing. In this example, the indications  111  are chapters, pages, lines, etc. for indicating a section that the reader reads. In the operation, for example, the first layer  12  is rotated to R and the third layer  16  is rotated to 10. Thus the user can know where he (or she) reads, in this example, it indicates that the place to be read next time is at line 10 from the right side of the page. However the present invention can also be used to indicate a date. In the example, the first layer  12  is rotated to an indication of 01, and the third layer  16  is rotated to 01, which represents a date of Jan. 1 so as to alert the user that at that day, a matter is necessary to be treated. However the present invention has many applications not confining to above said example. 
         [0041]    Preferably, the present invention is applied to name cards. When the name card is combined with the present invention, by the application of the present invention, the name card has more usages and thus the user may have deep impressions to name card. The name card will be retained with long time and the owners can view the name cards with higher frequency. Thus it generates an advertise effect, this is especially advantageous for the businessmen. 
         [0042]    In the following, the second embodiment of the present invention will be described with reference to the appended drawings. In this embodiment, those identical to the above embodiment will be identical to the same numerals. 
         [0043]    A base sheet  1  may have indication  111  on a surface thereof. One side of the base sheet  1  is printed with messages. Another side of the base sheet  1  has a shaft  11  for engaging other elements (see  FIG. 4A ). The shaft  11  may be formed by punching the base sheet  1  or is installed to the base sheet  1 . 
         [0044]    A multi-layer rotary disk has for example four layers including a first layer  12 , a second layer  14 , a third layer  16  and a fourth layer  18 . In this embodiment, the multi-layer rotary disk has an approximate round shape. Each layer has an axial hole  20 . A diameter of the axial hole  20  is slightly larger than a diameter of the shaft  11  for receiving the shaft  11  corresponding to the layers  12 ,  14 ,  16  and  18  so that the layers are rotatable with respect to the shaft  11 . Each layer of the multi-layer rotary disk has a window  22  and indication  111  which are at the same plane. In this embodiment, the indications  111  on each layer are numbers (such as 0, 1, 2, 3, 4, 5, . . . ) and English alphas (from A to Z)j [x]. The indications  111  are arranged around the axial hole  20  (referring to  FIGS. 5A to 5D ). 
         [0045]    In an optimum arrangement, an area of the layer at an upper side is not greater than that of a layer at a lower side so that the operation can be performed easily. 
         [0046]    In an optimum arrangement, an area of the layer at an upper side is not greater than that of a layer at a lower side so that the operation can be performed easily. 
         [0047]    A cap  3  can be engaged to the shaft  11  or is adhered to or glue to or sutured to the shaft  11 . The area of the cap  3  is greater than that of the shaft  11  for preventing the layers to release from the shaft  11  (referring to  FIG. 4B ). 
         [0048]    An operation example of the present invention will be described herein. In this example a window  22  of a fourth layer is rotated to 1; the third layer is rotated to 9, the second layer is rotated to 6 and the first layer is rotated to 7. It represents that an indication of chapter 1, section 9, paragraph 6 and line 7. 
         [0049]    In above two embodiments, the indication  111  may be numbers, constellations, arrows, alphas, textures, patterns, etc. 
         [0050]    Referring to  FIG. 7 , the shape of each layer in the multi-layer rotary disk is not confined to round shapes, it may be elliptical shapes or other regular shapes or irregular shapes, 
         [0051]    Referring to  FIGS. 8A to 8B , it should be noted that the number of the layers of the multi-layer rotary disk is not limited to four. 
         [0052]    Furthermore, it should be noted that in the present invention, the window may be a penetrating hole or a transparent area in the layer of the multi-layer rotary disk or indicators. 
         [0053]    Referring to  FIGS. 9A and 9B , the application of the present invention is illustrated. In this embodiment, the card of the present invention is used as a menu for selection of the combination of foods. For example, as illustrated in  FIG. 9A , it is illustrated that the first layer of the multi-layer rotary disk shows a plurality of desserts, and the second layer of the disk shows a plurality of juicy. Thus different desserts and juicy can be combined by dialing the layers of disk. Thus the customer can select a combination of the foods by using the rotary disk and then provides the disk to the waiter. 
         [0054]    Referring to  FIG. 10 , it is illustrated that the present invention is used with a car key. Thus when the driver has parked a car on a parking lot, he (or she) can record the number of the parking lot for the car on the multi-layer rotary disk so that the user need not remember the park lot number. 
         [0055]    Referring to  FIG. 11 , another embodiment of the present invention is illustrated. It is illustrated that the present invention is used as a calendar. In this embodiment, there are three layers on the rotary disk. A first layer shows the numbers from 1 to 31 representing different days of a month, the second layer repeatedly shows the numbers from 1 to 7 representing the different days of a week, and the third layer shows the number from 1 to 12 representing the number of months in one year. In use, the user just needs to align the three layers to a specific day. Then from the disk, he or she can know the information about the days in that month. 
         [0056]    Moreover, in the present invention, the multi-layer disk may be used to record the information of menses, such as safety period, critical period, and ovulation period. 
         [0057]    In the present invention, materials of the substrates and multi-layer rotary disks are selected from paper, plastics, metals, or non-metal, or the compound thereof. 
         [0058]    The present invention is thus described, it will be obvious that the same may be varied in many ways. Such variations are not to be regarded as a departure from the spirit and scope of the present invention, and all such modifications as would be obvious to one skilled in the art are intended to be included within the scope of the following claims.
