The ACR1281U-C8 is a dual-interface (contact & contactless) smart card reader from Advanced Card Systems (ACS). It is natively supported on Windows 11 without needing a separate driver download for basic CCID operation, but for full functionality (especially PC/SC and proprietary features), the official driver is recommended.
