Mobile adds the infrastructure that can turn a mobile device into a virtual credit card, supporting<br />

Host Card Emulation alongside the existing support of Universal Integrated Circuit Card (UICC)<br />

Secure Elements. That combination makes tap-to-pay systems possible on Windows <strong>10</strong> Mobile<br />

devices. It also enables tap-to-send apps for quickly sharing small pieces of data, as well as the<br />

ability to exchange data using NFC tags.<br />

Wi-Fi Direct This is a relatively new standard that allows devices to connect to one another<br />

over a wireless network in peer-to-peer fashion, without requiring an access point. New API<br />

support in Windows <strong>10</strong> means that applications can discover, pair with, and connect to devices<br />

automatically, without requiring user intervention. The same technology also can be used<br />

on enterprise networks to allow easy and secure connections to printers without requiring<br />

additional drivers or software.<br />

Miracast wireless display Miracast is another standard that uses Wi-Fi Direct to stream<br />

audio and video from a device to a Miracast-enabled display or projector. Miracast support<br />

is built into all Windows <strong>10</strong> devices, allowing users to pair a Windows <strong>10</strong> tablet or laptop to a<br />

conference-room projector with Miracast, and then project a presentation without wires or<br />

dongles. Microsoft’s Wireless Display Adapter, for example, shown in Figure 7-1, plugs into the<br />

HDMI input on a large television or other display, draws its power from a nearby USB port, and<br />

requires no setup.<br />

FIGURE 7-1 The small, unassuming Microsoft Wireless Display Adapter plugs into any HDMI-equipped<br />

display and accepts remote connections from any Windows <strong>10</strong> device using Miracast.<br />

Many of these connections can be made by opening Action Center and then tapping the Connect<br />

button, at the bottom of the pane beneath any waiting notifications. Figure 7-2 shows Windows <strong>10</strong><br />

ready to connect to a Microsoft Wireless Display Adapter, a Bluetooth-equipped PC, and a Bluetoothenabled<br />

audio headset.<br />
