With the increase in the number of NFC mobile phones, Huayang Micro NFC tags have increasingly become a common way to use this emerging technology. Through the NFC function, data can be transferred freely between mobile phones. Compared with the Bluetooth function, the establishment time of the NFC function is faster than the Bluetooth function, and compared with other communication functions, NFC has better security.
The usage of Huayang Micro NFC tags in various places
At home
BundleNFCThe label is affixed to the door or hung by the door, and set it to accomplish things such as: turn on Wi-Fi, dim the light, turn off Bluetooth, or auto-sync. With the NFC Task Launch app, you can set the tag to “switch”, then when you leave the house, you can touch the tag again to change these settings (such as turning off Wi-Fi)
While driving
Put the NFC tag near the dashboard or the middle control panel and set it to turn off Wi-Fi, turn up the volume, or turn on Bluetooth (mobile phone).
prepare to work
Put the NFC tag on the surface of the table and set it to dim the light, turn off the sound, turn on Wi-Fi, or automatically sync. According to your own preferences, you can also set it to enter the music application, open daily items, and even log in to Foursquare. If you set the label as a switch, you can touch it again when you leave to close the previous activity.
Bedside table
You can also put the label on the bedside table and set it to turn off the sound, turn on the alarm clock, turn off automatic synchronization, turn off light reminders, and turn down the light.
Mobile phone and Bluetooth speaker wireless communication
At present, the most popular applications are mobile phones and Bluetooth speakers. Using Huayang Micro NFC tags, you can connect the speakersBluetoothThe address is written in the Huayang Micro NFC tag chip, and then the mobile phone is approached to the speaker. The radio frequency (RF) sine wave generated by the mobile phone transfers energy to the tag, and then the data (Bluetooth address) is read from the tag for pairing. After NFC is started, the center frequency of the sine wave signal is 13.56MHz continuously. If there is a tag within the magnetic field disturbance range generated by the sine wave, the tag obtains energy from the magnetic field disturbance, generating the original sine wave inverse frequency or a wave with changed frequency properties. The mobile phone detects this change to know that there is a tag nearby to complete the communication pairing and transfer data.
At this time, you only need to adjust a relatively quiet ringtone, but you may not be able to machine this step every day. With the NFC tag, you can complete the ringtone and environmental mode adjustment functions with just one touch.
There is no need to find the phone setting menu and turn on Bluetooth to search step by step. Using Huayang Micro NFC can easily complete the Bluetooth pairing and connection between the phone and the speaker with one touch, eliminating the need for opening, searching, and selecting in the traditional Bluetooth connection method , Entering the pairing code and other complicated steps, just one touch to listen to music instantly.

NFC plays a huge role in the fields of access control, public transportation, and mobile payment. A small NFC tag can replace a large number of IC cards (including credit cards) occasions where shopping malls swipe cards, bus cards, access control, bus tickets, tickets and so on. In this way, there is a great advantage, that is, the card is powered by the RF domain of the non-contact card reader, even if the host device (such as a mobile phone) is out of power, it can still work.
This mode is similar to infrared and can be used for data exchange, but the transmission distance is shorter, the transmission creation speed is faster, the transmission speed is faster, and the power consumption is low (Bluetooth is also similar). Linking two NFC-enabled devices can realize point-to-point data transmission, such as downloading music, exchanging pictures, or synchronizing device address books. Therefore, through NFC, multiple devices such as digital cameras, PDAs, computers, and mobile phones can exchange data or services.
