Android 4 will provide the NFC-based Android Beam feature as well as Wi-Fi Direct and Bluetooth HDP for quick sharing between devices and peripherals.
NFC-Based Android Beam
Android Beam is an innovative, convenient feature for sharing across two NFC-enabled devices. It lets people instantly exchange favorite apps, contacts, music, videos - almost anything. It's incredibly simple and convenient to use - there's no menu to open, application to launch, or pairing needed. Just touch one Android-powered phone to another, then tap to send.

On the other device, the Market app launches and loads the details page, for easy downloading of the app. Individual apps can build on Android Beam to add other types of interactions, such as passing game scores, initiating a multiplayer game or chat, and more.
Face Unlock
Android 4 introduces a completely new approach to securing a device, making it even more personal. Face Unlock is a new screen-lock option that lets users unlock their devices with their faces. It takes advantage of state-of-the-art facial recognition technology to register a face and to recognize it later when unlocking the device. Users just hold their devices in front of their faces to unlock, or use a backup PIN or pattern.
Wi-Fi Direct and Bluetooth HDP
Support for Wi-Fi Direct lets users connect directly to nearby peer devices over Wi-Fi, for more reliable, higher-speed communication. No internet connection or tethering is needed. Through third-party apps, users can connect to compatible devices to take advantage of new features such as instant sharing of files, photos, or other media; streaming video or audio from another device; or connecting to compatible printers or other devices.
Android 4 also introduces built-in support for connecting to Bluetooth Health Device Profiles (HDP) devices. With support from third-party apps, users can connect to wireless medical devices and sensors in hospitals, fitness centers, homes, and elsewhere. In addition, for connecting to higher quality Bluetooth audio devices, Android 4 adds support for Bluetooth Hands Free Profile (HFP) 1.6.
