This document describes the following guides for users on how to take a photo of receipt:
- A short guide.
- A detailed guide.
First of all, choose a good-lighted place or use a flashlight on your smartphone.
Then place the receipt with right orientation on a flat solid non-transparent surface.
Finally, while taking a photo pay attention to the distance from the receipt to the camera — receipt should occupy the major part of the photo as possible. No other text should be visible on the photo.
Receipt must be:
- good printed
The receipt should have bright text without any spots.
- photographed in good-lighted conditions.
The place where you are taking a photo should have good-lighted conditions and there should be no shadows and no noise on the receipt.
- not blurred
The receipt should have clear and contrast text and logos. Please don’t move the camera while taking pictures.
Please avoid significant non-linear distortion of the receipt. I.e. all four sides of the receipts should form a rectangle with right angles. For this, the phone and the receipt must be in parallel planes.
- with no semi-transparent text
It is not allowed that text from the back side of the receipt can be seen through the paper on the front side.
- put on a flat solid surface
A receipt should be on a flat solid surface large enough and with no gaps. It is not recommended to put the receipt on your knees or hold it in your hands while taking a photo.
he receipt should be flat — not bent or folded.
- not overlapped by other objects and no other text in the frame
There should be no other objects on the receipt.
- only significant information in the photo
When you have a big receipt with an empty area on it you should take a photo only of significant information without capturing empty areas or areas with non-important data. It will allow keeping a good resolution for the important data.
