Talking about infrared, Bluetooth, and NFC on mobile phones, I believe we are not silent. The first three technologies are used to transfer data between machines. With the emergence of a large wave of data exchange software and changes in demand, these functions were slowly cut off by mobile phone manufacturers.
In recent years, these technologies have been widely used in technological advancement. More and more mobile phones have started to incorporate these hardware, but their functions are no longer single. Infrared is mainly used as a remote control, and the application of NFC is more extensive. Bank cards and public transportation cards can be swiped.
Starting from the iPhone 6, Apple has built in NFC chips in its mobile devices, but it is not open to developers and can only be used for Apple Pay. In some areas in China, you can use the iPhone to swipe the subway, but it is not available nationwide. universal. What is more interesting is that you can still use Apple Pay for payment without network support.
For Android phones, the smart NFC chip has basically become the standard for the new machine. Thanks to the open features of Android, it can do more. Not only can it be used to swipe bank cards, but it can also brush subway buses. At present, the flagship models of Samsung, Xiaomi, Huawei, Meizu and Nubia are all equipped with smart NFC chips. It is sufficient to go out in the first-line cities and other developed cities to bring mobile phones.
So, Android phone can still be used in the case of no electricity? If you are using the NFC card function, it is an rfid card that can be read and used by the reader, such as the reading of a public transportation card; if it is The interactive communication function is not available.
Bank cards or other magnetic cards are uncharged, read or change card contents, and are externally supplied with power. Then the mobile phone NFC does not belong to the physical card. It belongs to the virtual card. It is the mobile phone software that exchanges information with the NFC receiving terminal, and the receiving terminal device does not give the NFC the power. Therefore, the power required by the NFC exchange information is provided by the mobile phone. The power required for NFC exchange of information is small. As long as the NFC function is turned on, even if the mobile phone is turned off, it can support several NFC information exchanges by relying on the battery power.
That is to say, as long as you have turned on the NFC function and set the default card swiping mode, you can directly swipe the mobile phone into the subway bus in case of shutdown. Theoretically speaking, this argument is true. It is okay to test the millet 6 by yourself. However, due to the fact that the specific implementation principles of various manufacturers may differ, the specific situation has to be measured by oneself.
