What does OCR stand for?

Can you please clarify what the acronym "OCR" stands for? I'm interested in understanding the context in which it's used, especially in relation to the field of cryptocurrency and finance. Is it a technical term that's specific to the industry, or is it a more general term that's applicable in other areas as well? I'd appreciate it if you could provide a brief explanation of its meaning and how it's used in the context of our discussion.
