4. An image data processing method as described in claim 1 , wherein, if a storage result report indicating that the image data was not stored successfully is received, then the processing method determined by the host computer includes a method for terminating the transaction.

5. An image data processing method as described in claim 1 , wherein the storage result report includes information relating to the size of the stored image data.

6. An image data processing method as described in claim 1 , further comprising presenting the storage result report.

7. An image data processing method as described in claim 6 , wherein the image scanning apparatus comprises an indicator unit, and the presenting step comprises presenting the storage result report using the indicator unit.

8. An image data processing method as described in claim 6 , wherein the host computer comprises a display device, and the presenting step comprises presenting the storage result report using the display device.

9. An image scanning apparatus for processing scanned image data according to commands issued by a host computer, comprising:

a scanner configured to acquire image data;

a primary storage medium configured to store the image data;

a transmitting unit configured to send to the host computer a storage result report indicative of a result of storing the image data in the primary storage medium, the storage result report not including the image data acquired by the image scanning apparatus; and

a processing unit configured to process the image data according to a processing mode determined by the host computer based on the storage result report;

wherein the storage result report includes information indicating whether the image data was stored successfully in the primary storage medium; and

a temporary storage medium configured to temporarily store the acquired image data before it is attempted to be stored in the primary storage medium; and

wherein, if a storage result report indicating that the image data was not stored successfully in the primary storage medium is received, then the processing mode determined by the host computer includes sending the image data stored in the temporary storage medium directly to the host computer without storing the image data in the primary storage medium.

10. An image scanning apparatus as described in claim 9 , wherein, if a storage result report indicating that the image data was stored successfully is received, then the processing mode determined by the host computer includes completing the transaction.

11. An image scanning apparatus as described in claim 10 , wherein, if a storage result report indicating that the image data was stored successfully is received, then the processing mode determined by the host computer includes sending the image data stored in the primary storage medium to the host computer.

12. An image scanning apparatus as described in claim 9 , wherein, if a storage result report indicating that the image data was not stored successfully is received, then the processing mode determined by the host computer includes terminating the transaction.

13. An image scanning apparatus as described in claim 9 , wherein the storage result report includes information relating to the size of the stored image data.

14. A POS terminal, comprising:

an image scanning apparatus comprising

a scanner configured to acquire image data,

a primary storage medium configured to store the image data,

a transmitting unit configured to send to a host computer a storage result report indicative of a result of storing the image data in the primary storage medium, the storage result report not including the image data acquired by the image scanning apparatus, and

a processing unit configured to process the image data according to a processing mode determined by the host computer based on the storage result report;

wherein the storage result report includes information indicating whether the image data was stored successfully in the primary storage medium;

a temporary storage medium configured to temporarily store the acquired image data before it is attempted to be stored in the primary storage medium; and

wherein, if a storage result report indicating that the image data was not stored successfully in the primary storage medium is received, then the processing mode determined by the host computer includes sending the image data stored in the temporary storage medium directly to the host computer without storing the image data n the primary storage medium; and

a terminal computer functioning as the host computer.

15. A POS terminal as described in claim 14 , further comprising:

a user-specific information reader configured to acquire user-specific information preprinted on the check; and

a transmitter configured to send the acquired user-specific information to the terminal computer;

wherein the terminal computer stores the sent image data and the user-specific information from the image data linked to each other.

16. An electronic payment system, comprising:

a POS terminal comprising

an image scanning apparatus comprising

a scanner configured to acquire image data,

a primary storage medium configured to store the image data,
