OCR, or Optical Character Recognition, is a technology that has been around for nearly a century and is the foundation of various practical applications we encounter in our daily lives. You might have heard of handheld scanners, experienced license plate recognition in parking lots, or even been amazed by identity document recognition. Optical Character Recognition is the process of converting images or scanned files into text data. In today's era of information explosion, traditional paper-based processing is no longer sufficient, making OCR an essential component of digital transformation for both businesses and public sectors.
