OCR, OBCR, OMR, and MICR are four technologies used to convert text and markings into machine-readable data. OCR converts printed or handwritten text into editable text using optical scanners. OBCR reads barcodes and converts the data within them into text. OMR recognizes pre-specified options marked on exam sheets to evaluate tests. MICR uses magnetic ink to print codes on checks that can be read even if overwritten. All four technologies aim to convert human-readable data into digital formats.

2. OCR
OCR stands for Optical Character Recognition or Optical
Character Reader.
It is the electronic conversion of handwritten or printed text
into machine-encoded text.
Use optical scanners for input.
This technology was developed early for creating reading
device for blinds.
Most commonly used to convert hardcopy output into
softcopy.

4. HOW DOES IT WORK?
Scans physical form of documents.
Converts the documents to black and white.
Further scans black part to find alphanumeric
digits.
After identifying character, it is converted into
ASCII code that can be used by computer.

7. OBCR
Barcodes are series of black and white bars used to
represent alpha-numeric information in various
combinations.
OBCR stands for Optical Barcode Reader.
It can read printed barcodes, decode the data present in
barcode and send the data to the computer.
Light sensor is used for translating optical impulses into
electrical signals.

9. HOW DOES IT WORK?
Scans the blank and white elements of barcode.
Generates analog signals which is sent to
decoder.
The decoder interprets the signals and convert it
into texts.

12. OMR
OMR stands for Optical Mark Recognition.
It is the process of recognizing pre specified
options.
This type of technology is used to evaluate the
papers of competitive examination.

14. HOW DOES IT WORK?
Optical mark reading is done with the help of device
called optical mark reader
Data that is to be interpreted is in the form of dots,
darkened circles or dots
These dots are identified by the OMR scanner when an
OMR sheets is passed through it and stores it to
separate files.

16. MICR
MICR stands for Magnetic Ink Character
Recognition.
It is the technology which use magnetic ink for
printing the code.
Used by banks while printing cheque.
MICR technology contains magnetic ink of iron
dioxide which can be read even if it is overwritten.
