Abstract

The present invention relates to a magnetic ink character recognition (MICR) for a check in an automated check processing machine, and more particularly, to a method of recognizing characters on a check in an automated check processing machine, in which only an MICR reading unit repeatedly reads magnetic ink characters several times or an MICR reading unit together with a scanner read magnetic ink characters on a check, then compares the magnetic ink characters, and corrects error codes, so that probability of MICR read error is reduced and a recognition rate of the check is enhanced.

Claims

1. A method of recognizing characters on a check in an automated check processing machine which includes a check receive-and-dispense unit for receiving and dispensing a check, an MICR reading unit for reading MICs of the check, a printing unit for printing a stamp on a surface of a normally processed check, a stacking unit for keeping the check, and a control unit for controlling the units of the automated check processing machine, the method comprising:

a first step for extracting the MICs of the check and partitioning the MICs into characteristic regions, by the MICR reading unit, if the check is input through the check receive-and-dispense unit;

a second step for converting codes of the characteristic regions into certain bit values;

a third step for temporarily storing the converted code data, re-extracting the MICs of the check for a predetermined number of times, and converting the codes into certain bit values, if an error code occurs while performing the code conversion; and

a fourth step for comparing the stored code data with newly converted code data, correcting the error code, and configuring a serial number.

2. The method as claimed in claim 1, wherein if the number of performing the third step exceeds a predetermined number, the check is determined as an invalid check and discharged to the check receive-and-dispense unit.

3. The method as claimed in claim 1, wherein in the third step, each time the MICs of the check are re-extracted, a speed of reading the MICs is reduced to a certain level.

4. The method as claimed in claim 1, wherein in the third step, when the MICs of the check are re-extracted, only MICs of a characteristic region having the error code are re-extracted.

7. The method as claimed in claim 1, further comprising a fifth step of confirming whether the check is valid by transmitting the serial number of the check to the control unit, if the serial number is configured.

5. A method of recognizing characters on a check in an automated check processing machine which includes a check receive-and-dispense unit for receiving and dispensing a check, an MICR reading unit for reading MICs of the check, a scanning unit for image processing and recognizing the check, a printing unit for printing a stamp on a surface of a normally processed check, a stacking unit for keeping the check, and a control unit for controlling the above parts, the method comprising:

a first step for extracting the MICs of the check and partitioning the MICs into characteristic regions, by the MICR reading unit, if the check is input through the check receive-and-dispense unit;

a second step for converting codes of the characteristic regions into certain bit values;

a third step for temporarily storing the converted code data, requesting image data from the scanning unit, and receiving the image data, if an error code occurs while performing the code conversion; and

a fourth step for converting codes of the image data, comparing the temporarily stored code data with the converted code data of the image data, correcting the error code, and configuring a serial number.

6. The method as claimed in claim 5, wherein in the fourth step, when the temporarily stored code data are compared with the converted code data of the image data and the error code is corrected, the temporarily stored code data has a priority.
