7 Proven Ways to Fix Unreadable Receipt Scans

Why does it often fail? Here’s how to fix unreadable receipt scans

Many people think that as long as their camera is high-end, receipt scans will always be successful. In reality, environmental factors matter much more than your smartphone camera’s megapixel resolution. The main reasons for failure usually stem from three things: lighting, contrast, and focus. Let’s discuss each one in detail so you can understand how to fix unreadable receipt scans with a more scientific yet practical approach.

Lighting: Make sure there are no shadows covering the numbers

Light is both the best friend and the worst enemy of OCR technology. The most common problem isn’t a lack of light, but rather uneven light. Imagine you’re holding a receipt under a room light that’s directly above your head. Your hand or smartphone will likely cast a shadow over the receipt. To an AI, these dark shadows can be mistaken for text characters or might even cover crucial info like the total amount. The fix for unreadable receipt scans in this case is to find diffuse light.

Try moving closer to a window during the day or use a room light that doesn’t shine straight down at the receipt. If you have to use a flash, watch out for reflections on thermal paper, which tends to be glossy. This glare will wipe out text details, leaving them as solid white in the photo. If this happens, turn off the flash and use bright enough ambient lighting.

Background: Use a dark surface for white receipts

Did you know that AI works by looking for contrast? Shopping receipts are usually white or light cream. If you place them on a white table or light-colored bedsheets, the scanning algorithm will struggle to figure out where the receipt’s borders end. A very effective way to fix unreadable receipt scans is to use a contrasting background, like a dark wooden table, a black mousepad, or even a dark-colored tiled floor. With a dark background, the receipt edges will be crystal clear, allowing the AI to perform a perfect ‘auto-cropping’ process and focus only on the text inside.

Camera Focus: Avoid blurry or shaky photos

Smartphone cameras today are great, but sometimes auto-focus can be fooled by the texture of the paper. Make sure to tap your smartphone screen exactly on the receipt’s text area before hitting the shutter button. Don’t rush to move your hand after pressing the button, as slow shutter speeds in indoor lighting can cause ‘motion blur.’ Even a slightly shaky photo is enough to make the number ‘8’ look like a ‘0’ to the AI. The way to fix unreadable receipt scans is to ensure your hand is steady, or if needed, rest your elbows on a table for extra support to prevent camera shake while shooting.

Technical steps to make it easier for AI to recognize your receipt

Now that we’ve handled the environmental factors, it’s time to focus on the physical condition of the receipt itself. Often, the receipts we get from the cashier are already folded or wrinkled because they were stuffed into a tight pocket or wallet. This messy physical state is a major enemy to the efficiency of your favorite aplikasi pengatur keuangan. Let’s look at the proactive technical steps you can take as part of fixing unreadable receipt scans. Mastering how to fix unreadable receipt scans through these detailed technical measures can significantly improve accuracy.

Flatten receipt folds manually

Curvatures in the paper will refract light and create distortion in letter shapes. If your receipt just came out of your wallet, don’t photograph it immediately. Take 5 seconds to flatten it by hand on a flat surface. If the receipt is heavily curled, you can gently fold it in the opposite direction or use heavy objects like keys or coins on the corners to keep it flat. Remember, a flat surface means even light distribution, which is the ultimate key to fixing unreadable receipt scans.

Ensure all four corners are within the camera frame

Many users try to photograph the receipt too closely (zoomed-in) just on the total price. However, modern OCR algorithms often need context from the entire receipt to identify the merchant’s name, transaction date, and tax structure. To fix unreadable receipt scans, make sure all four corners of the paper are within the photo frame. Leave a little margin between the edge of the receipt and the edge of the camera frame. This helps the AI perform perspective correction if you take the photo from a slightly tilted angle.

Clean the camera lens of fingerprints

This sounds trivial, but it’s often a major cause of failure. Our smartphones are constantly moving from hands to tables to pockets. Oil or fingerprints on the camera lens will create a ‘soft focus’ or foggy effect on the photo. Before starting the process to fix unreadable receipt scans, get into the habit of wiping the rear camera lens with a soft cloth or the clean inside of your shirt. Sharp, clear photos will increase character recognition accuracy many times over.

Common mistakes that cause receipts to fail processing

On our journey to mastering how to fix unreadable receipt scans, we also need to recognize the common ‘sins’ users commit that make AI systems give up. Understanding the limits of technology will help you manage expectations and know when to take alternative actions.

Forcing a scan on a receipt with completely faded ink

Thermal paper has a major weakness: it’s sensitive to heat and friction. If you find an old receipt at the bottom of your bag with text that’s almost gone, don’t force the AI to read it. Even if you’ve followed all the instructions on how to fix unreadable receipt scans, if the original data is physically gone (faded), the AI can’t ‘guess’ those missing numbers. In this situation, manual input is the only logical way out.

Taking photos in a room that’s too dim

Darkness is the enemy of accuracy. When light is low, the smartphone camera sensor increases ‘ISO,’ which results in noise or digital grain in the image. This noise is very disruptive to OCR algorithms because it makes the lines of the letters less sharp. If you’re in a dimly lit restaurant, don’t be surprised if your attempt to fix unreadable receipt scans doesn’t work instantly. The solution: ask a friend to shine their smartphone flashlight from the side (not from above) to light up the receipt without creating a direct reflection into the camera.

Using a photo angle that is too slanted

Taking a photo of a receipt from the side to make it look ‘aesthetic’ might be great for social media, but it’s bad for financial tracking. An angle that is too slanted will cause severe perspective distortion. Letters that should be rectangular can look like trapezoids. While AI has ‘deskewing’ features to straighten images, the accuracy will drop drastically. The correct way to fix unreadable receipt scans is to hold your smartphone parallel to the receipt’s surface (top-down view). Ensure the camera sensor plane is parallel to the paper plane.

Scenario: What should you do if the receipt still can’t be read?

Let’s be honest: sometimes, even after trying everything to fix unreadable receipt scans, the system still fails. Maybe it’s because the printer ran out of ink, resulting in broken text, or the receipt is torn exactly at the price section. Don’t let this stop your intention to hemat uang belanja and stay disciplined in your tracking. At MoneyKu, we believe that flexibility is key.

Use the manual input feature as an alternative

Technology is there to help, not to hinder. If after two scan attempts it still fails, switch to manual input immediately. The fastest way to fix unreadable receipt scans in an emergency is to just type in the total amount first. Don’t spend 10 minutes trying to scan a single damaged receipt. Remember, the main goal is to get the data recorded, not for the process to look high-tech.

Save the receipt photo as proof of transaction

Even if OCR fails to read the text automatically, the receipt image still has value as physical proof. In many modern finance apps, you can attach the receipt photo to a manual expense entry. This is a smart strategy to fix unreadable receipt scans because if you ever need to audit or complain to a store later, you still have a digital copy of the original receipt, even if you had to type the price yourself.

Take advantage of automatic categories to speed up recording

If you have to enter data manually because the fix for unreadable receipt scans didn’t work, the app will usually help by offering category suggestions based on your transaction history. For example, if you record at a specific convenience store location, the app can automatically suggest the ‘Household Needs’ category. This minimizes friction during manual input, so you can maintain consistency in tracking your finances even when the scan feature is unavailable.

FAQ: Popular questions about digital receipt scanning

Here are some questions that often pop up in the user community as they dig deeper into how to fix unreadable receipt scans and how this tech works behind the scenes.

Can the app read very long receipts?

Yes, but it’s a challenge. Long monthly shopping receipts are often hard to photograph in one frame without making the text too small. The fix for unreadable receipt scans for long receipts is to split it into several photos if your app supports it, or make sure you shoot from far enough away with very strong lighting so the small text stays sharp. Some advanced apps have a ‘panorama scan’ feature that lets you slide the camera from top to bottom following the length of the receipt.

Why is the total amount often detected incorrectly?

This usually happens because of other nearby numbers, like receipt numbers, dates, or tax calculations (VAT). If the store’s receipt format is non-standard, the AI might mistake the VAT amount for the total price. This is why it’s important to review the scan results before saving them. The way to fix unreadable receipt scans in this context is to always perform a quick verification on the final number detected by the system.

How do I scan a receipt that has been cut off?

If the total price part is missing or cut off, the AI won’t be able to find it. However, if only the header (store logo) is cut off, you can still scan the rest. The fix for unreadable receipt scans if the receipt is cut is to focus on the area that still has crucial data: item names, prices, and the total. If the total is missing, you might have to sum up the item prices manually or use the in-app calculator.

Is the data from receipt scans safe and private?

Privacy is paramount. Make sure you use a trusted app. Most OCR processes these days are done locally on your device or through encrypted servers. Before you try various ways to fix unreadable receipt scans, make sure you’ve read the app’s privacy policy regarding how they handle your transaction data. MoneyKu itself prioritizes user privacy by ensuring your financial data remains secure and is not misused.

Conclusion: Consistency is the Key

Understanding how to fix unreadable receipt scans is technical, but the goal is noble: making your life easier in managing money. Don’t let small obstacles like a failed receipt scan break your spirit in building better financial habits. Technology will keep evolving, and OCR accuracy will get closer to perfection over time.

But in the end, tools are just tools. What matters most is your intention to keep hemat uang belanja and always stay aware of where every cent you earn is going.
