An IC Card Reader Driver (also known as Smart Card Reader Driver) is a software component that allows a computer to communicate with an Integrated Circuit (IC) card reader. An IC card, often referred to as a smart card, is a small, portable device with embedded memory or a microprocessor that stores and processes data. These cards are commonly used for applications such as secure access (e.g., building entry), payment systems (e.g., credit cards), and identity verification (e.g., government ID cards).

The IC Card Reader Driver enables the operating system to detect and interact with the card reader hardware, allowing the system to read from or write to the IC cards connected to the reader.
