In this article, we will introduce our top 10 OCR Receipt, how to choose and access the right engine according to your data.
OCR Receipt is a tool powered by OCR (Optical Character Recognition) to extract and digitalize meaningful data from scanned or PDF receipts. Fields commonly captured by OCR receipt include description, quantity, due date, line items, merchant and store information, unit price, bill to, receipt number, total amount, tax amount, etc.
This technology is built on multiple steps :
The first step consists of preprocessing the image, usually the scanned receipts are noisy so a preprocessing with noise removal and gray scaling are needed. This step is necessary for the text extraction engines to work well.
Next step is text detection with OCR. It extracts a text from various file types: PDF, DOCX, JPEG, PNG, etc. Their goal is only to get the texts in the document without dealing with the structure of the document.
The final step consists of data extraction and categorization, where it classifies the extracted text into keys and tags like tax and total amount, it's based on deep learning algorithms and NER (Named Entity Recognition).
The final result of the parsing is a structured form that can be readable by the computer. It’s often a JSON, XML or even a CSV file; this makes it easy to be stored into a database and automatically analyzed.

OCR traces its roots back to telegraphy. On the eve of the First World War, physicist Emanuel Goldberg invented a machine that could read characters and convert them into telegraph code. In the 1920s, he went a step further and created the first electronic document retrieval system.
Early versions of OCR had to be trained with images of each character and were limited to recognising one font at a time. In the 1970s, inventor Ray Kurzweil commercialised “omni-font OCR”, which could process text printed in almost any font.
OCR Technology became popular in the early 1990s while attempting to digitize historic newspapers. In the early 2000s, OCR became available online as a cloud-based service, accessible via desktop and mobile applications.
Today, there’s a host of OCR service providers offering technology (often accessible via APIs) capable of recognising most characters and fonts to a high level of accuracy.

Microsoft Azure offers an OCR service as part of its Computer Vision API, which can be used to extract text from receipt images. The API can recognize text in different languages, as well as handwriting, and return structured data such as the total amount and date of the receipt. In addition, it can also extract key-value pairs from the receipt. This allows developers to easily integrate the receipt recognition functionality into their applications and automate tasks such as expense tracking and accounting.

OCR receipt can be used in many areas as it is the backbone of many businesses, especially in the area of supply chain management since it streamlines and optimizes various processes. Digitizing inbound data allows companies to manage tasks, information and production more efficiently and control costs. This digitization also improves on-time delivery, as manual data entry can lead to delays and inaccuracies throughout the supply chain.
Automating the capture and management of receiving data with OCR technology results in substantial time and efficiency savings, making it a critical aspect of a successful supply chain strategy.
Companies and developers from a wide range of industries (Social Media, Retail, Health, Finances, Law, etc.) use Eden AI’s unique API to easily integrate OCR Receipt tasks in their cloud-based applications, without having to build their own solutions.
Eden AI offers multiple AI APIs on its platform amongst several technologies: Text-to-Speech, Language Detection, Sentiment analysis API, Summarization, Question Answering, Data Anonymization, Speech recognition, and so forth.
We want our users to have access to multiple OCR Receipt engines and manage them in one place so they can reach high performance, optimize cost and cover all their needs. There are many reasons for using multiple APIs:
You need to set up a provider API that is requested if and only if the main OCR Receipt API does not perform well (or is down). You can use confidence score returned or other methods to check provider accuracy.
After the testing phase, you will be able to build a mapping of providers performance based on the criteria you have chosen (languages, fields, etc.). Each data that you need to process will then be sent to the best OCR Receipt API.
You can choose the cheapest OCR Receipt provider that performs well for your data.
This approach is required if you look for extremely high accuracy. The combination leads to higher costs but allows your AI service to be safe and accurate because OCR Receipt APIs will validate and invalidate each other for each piece of data.
Eden AI has been made for multiple AI APIs use. Eden AI is the future of AI usage in companies. Eden AI allows you to call multiple AI APIs.
