The NFC (Near Field Communication) feature of the iPhone allows users to make convenient wireless transfers, such as making payments, reading tags, or connecting with other devices. The NFC feature is enabled by default, but in some cases it may be disabled or required to be manually activated. Below I will detail how to turn on and use the NFC feature on Apple phones.
Check whether NFC is enabled. First of all, you can check if the NFC function is already turned on. Workaround: Open the Settings app. Then select "General". In the "General" settings page, find and click on the "NFC" option. Make sure the NFC function switch is turned on, and if it is not, turn it on.
Use the NFC function. Once the NFC function is turned on, you can start using it for various operations, such as reading tags or connecting other devices. Read the tag: If you want to read the information on the NFC tag with your phone, simply point the back of your phone at the tag. Connect devices: Some devices or accessories support NFC connection, and you can quickly connect and pair your phone close to the NFC area of the device or accessory.
In summary, the NFC function of the Apple phone can be found and turned on under the "General" settings in the "Settings" app, and after it is turned on, you can read the tag or connect to other devices.
