iPhone 11 is not much different from iPhone XR in design. It is still an aluminum alloy frame and front and rear glass panels, but the back adopts a dual-camera design, but the shape of the dual-camera module adheres to the style of Yuba. . The iPhone 11 is also available in six colors, namely purple, white, green, yellow, black, and red. The iPhone 11 uses a 6.1-inch LCD screen and supports Dolby Atmos. All three new iPhone 11 series support dual-SIM (nano-SIM) dual standby, and are not compatible with existing micro-SIM cards. According to reports, users can select data and voice SIM cards in the settings. The use of dual SIM requires the use of two mobile communications services (which may include restrictions on roaming). Simultaneous use of two CDMA mobile communication services is not supported. Only some carriers support dual VoLTE. Certain restrictions apply. 1. Open the “Shortcut Commands” on the desktop.

VII My nfc can’t scan the key, ask the old driver to lead the way
What key to scan? Is that the kind of door keychain?
If it’s that kind of keychain, you can’t scan it, because the door disable technology is 125kHz, and the NFC’s operating frequency is 13.56MHz, and the operating frequencies are different. How can their coils induce each other? Well, without induction, the chip won’t work, so you can’t read the information.
Now there is a 13.56MHz access control system, but the cards for this kind of access control are generally relatively large (generally more than 1000 square millimeters). For this kind of card, you scan it with the NFC of your mobile phone. As long as the hardware is ok, the mobile phone will generally have a sensed sound, which means that the hardware is OK, but there may not be software on your mobile phone that can display the read data. information, so it’s still useless.
In addition, the NFC chip can be added�� For communication, if the card is encrypted, you don’t need special software to display it, you won’t see any data, and it will be garbled when you see it.
Ⅷ The NFC scan of the mobile phone does not show whether it is broken or not at the top of the screen.
The mobile phone NFC has an antenna, which mainly depends on whether your antenna is still moving. No effect anymore.
If not, it is possible that the NFC switch is turned off in the settings.

Now there are many nfc For example, Lakala, Bohai Bank, IGRS, etc. all have their own apps. However, there are still a lot of bugs. Generally, it is to turn on the nfc function of the mobile phone, and then cooperate with the app. Can be brushed. If you can’t solve it, you can ask customer service or something. Hope it helps you.
