ACS APDU Bridge is a free Chrome extension designed to facilitate communication between smart card readers and web applications. This add-on enables developers to send APDU commands directly to smart card readers, allowing for efficient smart card operations within HTML and web-based applications. By acting as a bridge, it simplifies the process of integrating smart card functionalities into custom web solutions.

The extension is particularly useful for developers who require real-time interaction with smart cards from their web applications. It efficiently forwards commands from the web to the connected smart card reader, retrieves the responses, and delivers them back to the application. This functionality is essential for applications needing secure authentication, data transactions, or any smart card-related operations, making ACS APDU Bridge a valuable tool for enhancing web application capabilities.
