| OCR, or Optical Character Recognition is the electronic translation of printer data into machine values. Over the years, OCR software has improved both in the reliability and the speed of the translations. The MicroVision Camera systems have OCR translations features built into the software. While it is recommended that a font designed for OCR is used, it is not required. The advantage of using OCR is that it is very simple to print, and human readable. The disadvantage is, at the end of the day, it is a translation, which can be incorrect because of something as simple as a streak across the number 6, that makes if look like an eight, caused by a bad laser drum.
There are quality control procedures that can enhance the integrity of OCR processing, for example sequential order checking, or using a check digit, but barcodes are more reliable.
Remember, when using OCR translation, the software has to take the time to translate every character from every possibility. It you are translating a 7 digit number, it that has 10 possibilities numbers for every digit. If you are translating an address block with 70 characters, it has 26 upper alpha characters, 26 lower alpha characters, any special characters, and 10 numbers per character to translate.
MCS MicroVision systems have a OCR text block feature, which allows the user to compare text blocks to field in data files. While this technology is better then manual systems, it is not as useable as OCR sequence numbers or barcodes.
