YubiKey NEO

The YubiKey NEO has five distinct applications, which are all independent of each other and can be used simultaneously. Note: Some software such as GPG can lock the CCID USB interface, preventing another software from accessing applications that use that mode.

Interface

The YubiKey NEO has USB 2.0 and NFC interfaces. All of the applications are available through these interfaces. The NFC interface also supports MIFARE Classic 1k.
