Unformatted text preview: use bar codes to identify and track each packet. For example, Federal Express of USA uses a unique bar-coding system and their employees can usually tell a customer within a matter of minutes the current location of any packet. Magnetic-Ink Character Recognition (MICR) MICR is similar to OCR and is used by the banking industry for faster processing of the large volume of cheques being handled every day by this industry. Banks that employ MICR technology use a special type of cheque. The bank's identification code (name, branch, etc.), account number, and the cheque number are pre-printed (encoded) using characters from a special character set on all these cheques with a special ink that contains magnetizable particles of iron oxide before the cheques are given to the customers for use. A sample cheque that employs MICR technology is shown in Figure 9.14. When a customer presents a filled-in cheque at a bank, a bank employee manually enters (keys in) the amount written on the cheque in the lower right corner of the cheque using an MICR inscriber, which prints the amount with the magnetic ink. The date of the transaction is automatically recorded for all cheques processed that day. This cheque is then processed using an MICR reader-sorter, which can recognize magnetic ink characters. The MICR reader-sorter reads the data on the cheques and sorts the cheques for distribution to other banks or for further processing. The most commonly used character set by MICR devices is known as E13B font that consists of the numerals 0 to 9 and four special characters as shown in Figure 9.15. Coded data in the form of these fonts are transferred from cheques to the computer by an MICR reader-sorter. As the cheques enter the reading unit, they pass through a magnetic field, which causes the particles in the ink to become magnetized. Read heads then interpret these characters by examining their shapes. The sorter is basically used to sort the cheques into different pockets according to their identification code numbers. MICR technology speeds up data input for the banking industry because cheques can be dire...
