How to build a credit card scanner with React Native

In the article, the author explains how to integrate a credit card scanning feature into a React Native app using the Text Recognition API, part of the ML Kit, which recognizes Latin-based characters. The process involves creating a new React Native project, setting up the necessary libraries, and writing custom logic to recognize credit card numbers from images captured via the device's camera or selected from the photo gallery. The article details the use of libraries such as react-native-cardscan, which is deprecated, prompting the use of react-native-text-recognition, and highlights the steps to handle image capture, text recognition, and processing for identifying valid credit card numbers. Additionally, the tutorial provides code snippets for setting up permissions, handling UI elements, and formatting recognized credit card numbers, offering a comprehensive guide for developers to enhance mobile applications with automated data entry features beyond credit card scanning.
