The EZ100PU remains a functional and useful smart card reader on Windows 11, but it requires users to accept a compromise between security and compatibility. The core issue—driver incompatibility with Memory Integrity—stems from the device's age and its manufacturer's decision to discontinue support.
For this reason, many experts and experienced users strongly recommend replacing the EZ100PU with a newer, modern smart card reader that natively supports Windows 11. Newer readers, such as the aibo IT-680U, are often "plug and play" on Windows 11. They use the standard CCID (Chip Card Interface Device) driver built into Windows, meaning no manual driver installation is required and, crucially, they work seamlessly with Core Isolation and Memory Integrity enabled. This provides a hassle-free experience without compromising system security.
