With this processed data, the scanner can generate a comprehensive digital record of the receipt, allowing users to effortlessly store, organize, and analyze their expenses digitally.

Optical Character Recognition (OCR) technology

Optical Character Recognition (OCR) technology is a revolutionary development that enables the conversion of printed or handwritten text into machine-readable text. It uses advanced algorithms and image processing techniques to analyze and interpret the characters present in a document.

The process of OCR involves several steps. First, the scanner captures an image of the document, such as a receipt, using a digital camera or a traditional flatbed scanner. The image is then processed by the OCR software, which identifies the individual characters by analyzing the shapes, patterns, and other visual features.

OCR technology employs a technique called feature extraction, where the software identifies and isolates the key elements of each character, such as lines, curves, and intersections. It then compares these features with a database of known characters to determine the closest match.

During the character recognition process, OCR software also takes into account various factors that may affect the accuracy, such as the font style, size, and quality of the document. It utilizes machine learning algorithms to improve accuracy by continually updating its database with new characters and patterns.

Once the characters are recognized, the OCR software converts them into machine-readable format. This can include text files, searchable PDFs, or other digital formats. The converted text can then be easily edited, searched, or integrated into other applications.

Machine learning algorithms

Machine learning algorithms play a crucial role in how receipt scanners work. These algorithms are complex mathematical models that enable the scanning software to learn and make predictions based on patterns and data.
