In recent years, with the rapid development of information technology, people's lives have also changed. Many intelligent ways have gradually been applied to every corner of life. Electronic payment has gradually become the first choice for travel, while nfc is a common one. As long as the mobile phone supports this function, whether it is by bus The subway or payment is OK.
What is the nfc function on the mobile phone?
1. Bus card recharge
The first, of course, is to recharge the public card. With the NFC function enabled, the public card (Beijing area) can be close to the back through Alipay/WeChat, which can automatically identify the remaining balance in the card, and support WeChat payment/Alipay expenditure for recharging.
2. Alternative bank card
With the replacement of a new generation of bank card with a chip card, it basically has a flash payment function. It doesn't need to use a magnetic stripe card to draw around, but it can be paid with a touch.
3. Transfer files
On the NFC official introduction page of the mobile phone, it was written that you can share the website, contacts and applications on the device by placing your mobile phone next to another mobile phone that supports Android Beam. When using NFC to transfer files, Bluetooth is forced to open. In essence, Bluetooth is still used to transfer files, and the speed will be slightly faster.
Is it better to turn nfc on or off?
It is recommended to turn off the nfc function when the phone does not use it
The NFC function of the phone will consume more power, but the power consumption is very small. The NFC function of mobile phones must be available only for mobile phones with NFC chips. The operation of NFC chips also requires electricity, but only a small amount of electricity.
To put it simply, nfc has two working modes. One is the active working mode used to identify the contents of nfc tags, and the power consumption is very low; The other is passive operation mode, which is used for reading by other nfc devices. This mode consumes almost no power.
NFC near-field communication technology is evolved from the integration of non-contact radio frequency identification (RFID) and interconnection technology. It can identify and exchange data with compatible devices in a short distance by combining inductive card readers, inductive cards and point-to-point functions on a single chip; Nfc now has some bluetooth functions that can control bluetooth power on and power off!
