Middleware CIE is a utility software designed for Windows that facilitates secure online access to public administration services using the Electronic Identity Card (CIE). This free tool plays a crucial role in establishing a secure connection between the smart card reader and the microprocessor of the CIE, enabling users to authenticate themselves seamlessly through their web browsers, such as Internet Explorer, Firefox, or Opera.

Users are required to enter a PIN received during the CIE application and delivery phases to unlock the key and complete the authentication process. This ensures that the interaction remains secure and user-friendly, allowing for efficient access to various public services with minimal effort. Middleware CIE is essential for anyone looking to utilize their Electronic Identity Card for online transactions with public authorities.
