Financial device and method of controlling financial device

1. A financial device comprising:

an insertion part to which a medium is inserted;

a random number generation unit configured to generate a signal including information on a copying prevention number for preventing skimming of the medium;

a detection unit installed near the insertion part and configured to generate a detection signal by detecting the existence of the medium; and

a controller configured to control the generation of the copying prevention number by identifying a state of the medium according to the detection signal,

wherein the financial device further comprising:

a determination unit configured to determine whether the medium has been completely inserted or is being removed based on the detection signal; and

a card reader unit installed at one position of a movement path of the inserted medium and configured to recognize information included in the medium,

wherein the controller generates an on signal for the operation of the random number generation unit and, when it is determined that the medium has been completely inserted as the state of the medium, generates an off signal to make the random number generation unit not operate and, when it is determined that the medium is being removed as the state of the medium, generates the on signal to make the random number generation unit operate again,

wherein the financial device further comprising a receiver connected to an external server corresponding to a server of a company related to the medium or a bank through a network and configured to receive information on a first copying prevention number,

wherein the random number generation unit generates a first signal including the information on the first copying prevention number and transmits the first signal to the external area.

2. The financial device of claim 1 , further comprising a transmitter configured to transmit skimmer operation information indicating that the skimmer is operating to a terminal of a security manager when the information on the first copying prevention number is recognized from the medium.

3. The financial device of claim 1 , further comprising a data storage device configured to store the information on the first copying prevention number,

wherein the card reader unit additionally recognizes the information included in the medium by comparing it with the information on the first copying prevention number stored in the data storage device.

4. The financial device of claim 1 , further comprising a removal device configured to remove the medium when the information on the first copying prevention number is recognized from the medium.

5. A financial device comprising:

an insertion part to which a medium is inserted;

a random number generation unit configured to generate a signal including information on a copying prevention number for preventing skimming of the medium;

a detection unit installed near the insertion part and configured to generate a detection signal by detecting the existence of the medium; and

a controller configured to control the generation of the copying prevention number by identifying a state of the medium according to the detection signal,

wherein the financial device further comprising:

a determination unit configured to determine whether the medium has been completely inserted or is being removed based on the detection signal; and

a card reader unit installed at one position of a movement path of the inserted medium and configured to recognize information included in the medium,

wherein the controller generates an on signal for the operation of the random number generation unit and, when it is determined that the medium has been completely inserted as the state of the medium, generates an off signal to make the random number generation unit not operate and, when it is determined that the medium is being removed as the state of the medium, generates the on signal to make the random number generation unit operate again,

wherein the financial device further comprising a random number generation unit configured to generate a second copying prevention number corresponding to a random number unrelated to the medium number, wherein the random number generation unit generates a second signal including information on the second copying prevention number and transmits the second signal to the external area,

wherein the financial device further comprising a data storage device configured to store the information on the second copying prevention number,

wherein the card reader unit additionally recognizes the information included in the medium by comparing it with the information on the second copying prevention number stored in the data storage device.

6. The financial device of claim 5 , further comprising a removal device configured to remove the medium when information on the second copying prevention number is recognized from the medium.

7. The financial device of claim 5 , wherein the determination unit determines that the medium has been completely inserted when the detection signal is generated and then stopped, and determines that the medium is being removed when the detection signal is generated again.

8. The financial device of claim 5 , wherein the detection unit comprises a first sensor installed at a first position near the insertion part on the path and configured to detect the existence of the medium and a second sensor installed at a second position spaced apart from the first position by a predetermined distance and configured to detect the existence of the medium, and the determination unit determines that the medium is completely inserted when a detection signal of the second sensor is generated after a detection signal of the first sensor is generated.

9. A financial device comprising:

an insertion part to which a medium is inserted;

a random number generation unit configured to generate a signal including information on a copying prevention number for preventing skimming of the medium;

a detection unit installed near the insertion part and configured to generate a detection signal by detecting the existence of the medium; and

a controller configured to control the generation of the copying prevention number by identifying a state of the medium according to the detection signal,

wherein the financial device further comprising:

a determination unit configured to determine whether the medium has been completely inserted or is being removed based on the detection signal; and

a card reader unit installed at one position of a movement path of the inserted medium and configured to recognize information included in the medium,

wherein the controller generates an on signal for the operation of the random number generation unit and, when it is determined that the medium has been completely inserted as the state of the medium, generates an off signal to make the random number generation unit not operate and, when it is determined that the medium is being removed as the state of the medium, generates the on signal to make the random number generation unit operate again,

wherein the detection unit comprises a first sensor installed at a first position near the insertion part on the path and configured to detect the existence of the medium and a second sensor installed at a second position spaced apart from the first position by a predetermined distance and configured to detect the existence of the medium, and the determination unit determines that the medium is being removed when a detection signal of the first sensor is generated after a detection signal of the second sensor is generated,

wherein, when the detection signal of the first sensor is stopped after it is determined that the medium is being removed, the controller generates the off signal to make the random number generation unit not operate again.

10. The financial device of claim 9 , wherein the card reader unit recognizes the information included in the medium when a detection signal of a first sensor is stopped after it is determined that the medium is completely inserted.
