Android: What you can do with NFC

Near Field Communication, or NFC for short, is a transmission standard. This is used for contactless transmission of information over the shortest distance. All popular Android smartphones already support NFC. These have an NFC chip integrated. For older devices, you can upgrade the standard with the help of an NFC sticker. The sticker is attached to the back of the device. You have to hold your smartphone close to an NFC tag during data transfer. This subsequently activates various functions in the device. On Android devices, NFC can perform various tasks.

1. The transmission standard is often used in contactless payment. Depending on the store, you can thus pay with your smartphone directly at the cash register. However, you must first store your payment data in a corresponding pay app.
2. If you want to connect a Bluetooth device with your smartphone, you can save connection information on an NFC sticker. Anschließend müssen Sie Ihr Smartphone lediglich auf den Sticker legen, um die Verbindung herzustellen.
3. Dies funktioniert auch für andere Verbindungen, wie beispielsweise mit Ihrem WLAN-Netzwerk.
4. Zur Programmierung der NFC-Sticker können Sie diverse Apps nutzen, die Ihnen diesen Vorgang erleichtern.
