OCR, Explained: How Your Receipt App ‘Reads’ Like a Human (But Smarter)

What Is OCR?

OCR stands for Optical Character Recognition.
At its core, it’s a way for machines to “see” text in an image and turn it into real, editable data.

Imagine giving a receipt to a very fast, very accurate intern who looks at the picture, identifies words, ignores coffee stains, and types it all neatly into a spreadsheet. That’s OCR — except it never sleeps, never makes typos, and can process thousands of receipts a minute.

How Does OCR Actually Work?

Here’s a simplified version of what happens when you scan a receipt:

1. Image Preprocessing:
   The app sharpens and cleans the image so it can “see” better — think of it like putting on glasses.

2. Text Detection:
   It identifies where the text is on the page, even if the receipt is tilted or crumpled.

3. Character Recognition:
   It breaks the text into individual letters and matches them against known letter shapes using AI.

4. Contextual Understanding (Smart OCR):
   Here’s where it gets cool — modern OCR doesn’t just read the text; it understands it.
   It knows that “Total: $8.50” is the final amount, and that “02/06/2025” is likely the purchase date — even if it's printed in a weird font or next to irrelevant text.

5. Output Structuring:
   Finally, the data is sorted into neat categories: date, vendor, amount, tax — ready for your expense report.

Traditional OCR just recognizes letters. But modern tools (like the one inside Ezpense) use machine learning — they get better the more receipts they see.

That means your app can start recognizing oddball merchant names, regional tax formats, and even handwritten tips.
The more you use it, the sharper it gets.

If your app doesn’t have good OCR, you’re stuck manually editing things, chasing down blurry totals, or worse — misreporting expenses.

That’s not just annoying — it’s risky during audits or tax season.
