     TECHNICAL FIELD OF THE INVENTION 
     The present invention relates to the provision of additional information in relation to a removable storage medium. The present invention more particularly relates to a method of allowing the provision of additional information in relation to a removable storage medium equipped with a near field communication unit, a data processing device to be connected to a removable storage medium equipped with a near field communication unit, a computer program product for allowing the provision of additional information in relation to a removable storage medium equipped with a near field communication unit, a method of obtaining additional information in a data processing device in relation to a removable storage medium equipped with a near field communication unit, a data processing device for obtaining additional information in relation to a removable storage medium equipped with a near field communication unit, a computer program product for allowing the provision of additional information in relation to a removable storage medium equipped with a near field communication unit and a removable storage medium equipped with a near field communication unit. 
     DESCRIPTION OF RELATED ART 
     Removable storage mediums have for some time been used by users for storing data, like for instance in the form of diskettes and CD ROM discs. Traditionally these have been fairly large and had a surface where it is possible to write what content is provided on the disc by using a pen. However, nowadays these are becoming smaller and smaller and may for instance be provided in the form of USB memories and memory sticks. As a consequence there is nowadays virtually no surface on which to write down such information, which makes it hard to know what is on such a storage medium, especially if a user has many such mediums. 
     In order for a user to find out what is stored he would nowadays have to load the storage medium in his data processing device, which may be a regular computer or a portable electronic device such as cellular phone, and it is not possible to find out what information is stored on the device until that moment. The loading of a storage medium into a data processing device is tedious and can be time consuming for a user, especially if he/she has to check several such removable storage mediums before finding the medium he/she wants to use. 
     There has also recently evolved so-called NFC (Near Field Communication) chips that are used when two devices are in physical contact with each other. These chips are typically used for setting up of short range wireless communications, such as Bluetooth™ communications, or are used in relation to electronic payment schemes. 
     In view of the problems mentioned above, there is therefore a need for an alternative way to provide information about what content is provided on a removable storage medium in order for a user to locate the content in a simple way.

     DETAILED DESCRIPTION OF EMBODIMENTS 
     The present invention relates to a removable storage medium for a data processing device as well as such a data processing device. A data processing device according to the present invention may be a portable electronic device and then also a portable communication device, for instance a cellular phone. Such a phone  10  is schematically shown in a front view in  FIG. 1 . The phone  10  includes an information presenting unit in the form of a display  14 , which may be a liquid crystal display, a user interface for receiving inputs from a user in the form of a keypad  12  including a number of keys and a slot (shown as a dashed box) provided at a side of the phone  10  for receiving a removable storage medium, which medium when the device is a phone is preferably a memory stick. A cellular phone is just one example of such a device. It can also be such things as a lap top computer, a palm top computer, an electronic organizer, a smartphone, a communicator, a gaming machine or even a PC. 
       FIG. 2  schematically shows a removable storage medium according to an embodiment of the present invention. The removable storage medium is here a memory stick  18  which is provided with a near field communication unit in the form of a first NFC chip  20 . This NFC chip  20  also has a small limited size memory. The first NFC chip is a chip which is able to act as a passive echoing device when provided with a reading signal from a reading NFC chip. When it is provided as such a passive device it does not need any power, which the present invention takes advantage of. The removable storage medium is not limited to memory sticks, but may be any type of removable medium, like for instance a USB memory, a CD ROM disc or a diskette. 
       FIG. 3  shows a block schematic of relevant units in the phone of  FIG. 1  as the memory stick  18  with the associated NFC chip  20  inserted in the slot. The first NFC chip is here shown as being provided separate from the memory stick  18 . This is just done in order to clearly show that with regard to communication they are separate entities that do not directly interact with each other. The phone  10  here includes a control unit  22 , which is connected to the display  14  and the keypad  12  as well as to a file store  28 . The control unit  22  is furthermore connected to a near field communication reading unit in the form of a second reading NFC chip  30 . The control unit  22  is also connected to a first electrical interface  24  for the memory stick  18  and a second electrical interface  26  for the first NFC chip  20 . It should here be realized that the second interface  26  may not be needed, but that either the first interface  24  may be used for interfacing both the first NFC chip  20  and the memory stick  18  or that the second NFC chip  30  provided in the phone may be used as the interface instead. However, the first NFC chip  20  is here provided with power (not shown) from the battery (not shown) of the phone  10  in order for it to be able to receive additional data according to the principles of the present invention. The different units are here shown as communicating via the control unit  22 . It should however be realised that this communication may just as well be provided using a common data bus instead.  FIG. 3  furthermore shows the situation when the removable storage medium is connected to the phone in order to receive data files. It should here be realized that it may be more convenient for a user to use a computer for performing this than a phone. Therefore it should be realised that the units shown in  FIG. 3  may just as well be implemented in a PC or a laptop computer. 
     How additional data is provided to the removable storage medium will now be described with reference being made to  FIG. 3  and to  FIG. 4 , which shows a flow chart of a method of storing additional data in relation to data files stored in the storage medium. 
     As a user inserts his memory stick  18  into a data processing device, for instance the phone  10 , the control unit  22  detects the memory stick  18  being connected to the first electrical interface  24  and the first NFC chip  20  being connected to the second electrical interface  26 . In this way the user of the device  10  may move data files, for instance from the store  28  to the memory stick  18 , under the control of the control unit  22 . Here the user may be presented with files that can be moved to the memory stick  18  on the display  14  and may select what files to move via the keypad  12 . The selections are then received by the control unit  22 , which copies or moves the files from the store  28  to the memory stick  18 . In this way files elected by the user are stored in the removable memory stick, step  30 . Thereafter the control unit  22  presents the user with the option to provide additional data relating to the stored files. If the user declines this offer, step  32 , the method is ended, step  38 . However if the user accepts, step  32 , the control unit  22  awaits a selection of additional data from the user. The user may here provide additional data that he writes freely himself using the keypad, for instance data indicating a general context of the files. As an example he/she may, if the files are images captured by a camera, enter the text “vacation pictures summer 06”. The control unit  22  may also automatically extract data and store it in the first NFC chip  20 . If for instance the files were taken from a folder, the name of that folder may be automatically selected and stored in the first NFC chip  20 . It is also possible that there exists data associated with these files in the files themselves or as associated meta data where meta data may be the name of a movie, the name of an artist, the name of an album or a combination of such data. The control unit  22  may then automatically select this data for storage in the first NFC chip  20 . It is furthermore possible that the file name is automatically selected. There may also be a date associated with the one or more of the files, which may be the date of creation of the files. It is then also possible to select such data and store it in the first NFC chip  20 . The available storage space of the first NFC chip  20  may be limited, which is why a limitation of the data stored may be made. After a selection of additional data has been received in this way from a user or been made automatically, step  36 , this additional data is then transferred to the memory of the first NFC chip  20 , and here via the second interface  26 . When the data has been transferred, the method is ended, step  38 . 
     Now that a removable storage medium  18  has been provided with data files and also with additional data in the first NFC chip  20 , it may be removed from the data processing device and stored away. 
     The use of this same removable storage medium when the user wants to access the files on it, which may incidentally be made after a long time, will now be described with reference being made to  FIGS. 5 and 6 .  FIG. 5  shows a block schematic of the same units of the phone  10  as in  FIG. 3 . However, here the memory stick  18  is not inserted into the slot of the phone  10 , but is rather in physical contact or in close proximity of the phone  10 , so that the first NFC chip  20  can be reached from the second NFC chip  30  in the phone  10 .  FIG. 6  shows a flow chart of a method of retrieving additional data in relation to data files stored in the storage medium using these near field communication units  20  and  30 . It should here be realised that the device used for retrieving the additional data need not be the same device used for storing files in the removable storage medium. It may thus be a different device. However, one and the same phone is used here in order to simplify the description of the present invention. 
     As the user wants to investigate the content of memory stick  18 , he brings it in close proximity of or in touch with the phone  10 . Thereby the second NFC chip  30  of the phone  10  detects the presence of the memory stick  18  and reports this to the control unit  22 . The second NFC chip  30  is thus an active unit. The control unit  22 , when being notified of this, orders the second NFC chip  30  to send a reading signal to the first NFC chip  20 , which it then does, step  40 . As a response or echo to this reading signal, the first NFC chip  20  sends the additional data provided in the NFC memory, which data is received by the second NFC chip  30  and forwarded to the control unit  22 . The first NFC chip  20  does furthermore not need any power when responding. Thus it is here a passive unit. The control unit  22  thus receives this additional data, step  42 , and thereafter presents it on the display  14 , step  44 . 
     In this way, the user can immediately find out what type of content is provided on the memory stick by just moving the memory stick in contact or close to the phone. It is also done independently of the size of the stick. The user does not have to input the stick into the slot. The user also does not have to provide any power to the first NFC chip. In this way it is very easy for the user to check if the stick is the one he/she wanted to access. If it is not, it is just a simple matter of taking another memory stick and performing the same procedure on it. Therefore the present invention is also very user friendly and allows the provisioning of additional data when the surface of the removable storage medium is too small to have anything written on it. In this way, it is furthermore easy to change the additional data associated with a removable storage medium whenever the content on it is changed. 
     The control unit is preferably provided in the form of a microprocessor with corresponding program code for performing the various method steps. The program code can furthermore be provided on a data carrier such as a CD ROM disc  46  as shown in  FIG. 7  or another memory stick which performs a method of the present invention when being loaded into a data processing device. The program code may as an alternative be provided on a server, from where it is downloaded to the data processing device. 
     The second NFC unit need not be provided in a device where the files are loaded into the removable storage medium. However, it is of course needed in a device presenting the additional data. The device where the check of the additional data is made does also not need to include the second interface. The files stored in the removable storage medium may be any types of files, but different types of media files are preferred. It is furthermore possible that the additional data is provided by another party than the user, for instance by a supplier of the data files on the removable medium and not by the user. This may for instance be the case if the removable storage medium contains a game for a gaming machine. The number of files provided on the removable storage medium can also vary considerably. The number can for instance be as low as one data file. In view of the different variations mentioned above, the present invention is therefore only to be limited by the following claims and their equivalents.
