What are SmartTags?
SmartTags use your device's NFC capabilities to trigger instant actions. For example, they can activate multiple settings on your device, launch an application, turn on the Wi-Fi® function on your device, or link to a web page. You can also use a SmartTag as a personal business card.
SmartTags also offer pre-set scenarios designed to get you started quickly. For example, if you're going to sleep, one tap of a SmartTag can launch your Alarm application, set your phone to silent, and turn off all the applications that you don't need, such as Wi-Fi®, Bluetooth® and GPS.
