Almost all modern Android phones of secondary and higher price categories are equipped with chips that support NFC (Near Field Communication) – short-range wireless connectivity, which allows you to communicate with other devices over a distance of not more than 20 cm.

NFC 1

Using NFC you can pay in restaurants and coffee shops, visit gyms and fitness centers, hotels and amusement parks, pay for gasoline at the pump, order goods on virtual trade stands, and so on.

Smartphones with NFC are useful for advertising and marketing campaigns — for example, in many countries of the world in the underground and on bus stops there are NFC tags on advertising billboards. Scanning them using a smartphone, you can get the information about the product and get a discount on its purchase or bonuses, take part in the competition and win something.

Gestures and special keys

Navigate in the menu and iOS applications very conveniently with the help of gestures. Just hold your finger on the left edge of the screen to go to the last menu item. Swiping to the right corner (e.g. in a browser), you can go to step forward. On the iPad using gestures or four fingers, you can easily switch between running utilities or expand them to fill the screen.
