Detailed Description

Deprecated. Use CrescendoDLL.TokenChange (raised by CrescendoDLL.TokenManager.OnTokensChanged) instead. Represents a specific change that occurred to a smart card reader or token during monitoring.

Deprecated. This type backs the legacy CrescendoDLL.SDKCore.OnReadersChanged surface and is preserved for source compatibility with code written against SDK 2.x. This method will be removed in a future major release.

This class provides detailed information about state changes detected by the PC/SC monitoring system, including both the previous and current states for comparison.
