Bluetooth is no stranger to those who are familiar with digital products. Many mobile phones and digital products have integrated Bluetooth functions, such as a Bluetooth mouse, a Bluetooth keyboard, and a Bluetooth speaker. In addition, we can use Bluetooth to transmit photos and videos, which saves us the trouble of cables. However, Bluetooth has its own inconvenience, which is the trouble of setting up. Compared with Bluetooth, NFC has the advantage of simple settings, although its transmission distance is short. Perhaps you would wonder whether these two can bring their advantages into play to bring new ideas and new ways of playing?
First, let's take a look at their advantages and disadvantages. In terms of transmission speed, the maximum transmission capacity of NFC is 424kbit/s, which is far less than the 25Mbps of Bluetooth 4.0, so it is not suitable to use NFC to transmit photos and videos. In addition, the transmission distance of NFC is also far less than that of Bluetooth, but this is not a disadvantage of NFC. It is precisely because of the short distance communication characteristics of NFC that the use of NFC is so convenient that it can only be connected to one machine at a time without pairing like Bluetooth.

NFC has no complex settings to simplify Bluetooth connection
Although Bluetooth is an excellent short distance data communication technology, its disadvantage is that it needs pairing. Sometimes pairing of mobile phones takes much longer than transferring pictures. However, the pairing process can be simplified by combining with NFC.
NFC+Bluetooth: Using NFC as the initial handshake can make it possible to pair devices almost instantly, and then use Bluetooth for data transmission. Its advantage is that the user does not need to enter a verification code, and the pairing process is omitted. At the same time, it can achieve the transmission distance and speed of Bluetooth.
NFC and Bluetooth in reality
At Nokia's Lumia920 launch conference some time ago, Nokia and JBL jointly released a PowerUp wireless charging speaker that supports NFC functions. In addition to supporting wireless charging, this speaker can also quickly complete the pairing between the phone and the speaker through NFC, and then play the music in the phone wirelessly through Bluetooth. The whole process only needs to touch Lumia 920 slightly at the position where NFC should be located on the top of the speaker, instead of spending tens of seconds searching and pairing Bluetooth speakers as before.
We can see that the speaker of JBL PowerUp can not be completed so simply by relying on NFC and Bluetooth alone. If we rely on NFC alone, we can not achieve long-distance transmission. As long as the phone leaves the speaker signal, it will be interrupted, and it can not be completed by relying on Bluetooth alone, because Bluetooth pairing is cumbersome. A perfect transmission can be achieved by combining the convenience of NFC and the long-distance transmission of Bluetooth.

In addition, in terms of games, NFC can simplify the connection of multiplayer war games. For war games like Boxing King, you can link multiple Bluetooth devices through NFC's simple touch to connect operation. In addition, in homes and offices, Bluetooth printers with NFC functions will print photos directly from cameras equipped with similar functions through seamless processing. This printing process will become quite simple. Just put the device on the printer, select the picture to be printed, and then press the image sharing button.
