Data transmission

As early as four years ago in the Android 4.0 era, NFC features were integrated into the native Android system. The back-to-back Android beam near-field transfer feature requires only two NFC phones to be able to transmit data via NFC, eliminating the need for a series of paired steps compared to Bluetooth, which is fast and easy.

Public transport

Our daily use of the bus card is actually an NFC chip, so the NFC-enabled mobile phone can also read the bus card. Not only can view the bus card balance and consumption records, but also in recent years the new bus card to recharge, eliminating the problem of queuing at the recharge point. Even in some public transport facilities to open the NFC payment of the city, you can directly use the mobile phone to brush the bus, not even the card with.

Mobile payment

NFC is more secure than the popular QR code scan, which is not only non-replicable, but also does not access the user's private information.

Internet of Things

In the Internet of Things, NFC is the ability to connect mobile phones to other NFC-enabled products, such as a home router, to connect to Wi-Fi, some Bluetooth speakers, or to connect via NFC.

Realty management

What kind of mobile phone has NFC currently on the market?

In fact, since the beginning of Android 4.0 Google has paved the way for all kinds of NFC applications, but NFC in China did not have much space so there is no large-scale popularization, there are few NFC-enabled mobile phones on the market. In the Android 7.0 era, whether it is home-made brands or foreign brands, even at the price of only hundreds of cheap machines we can see NFC figure. The popularity of NFC has not changed much since the mobile payment is hot.

Although each manufacturer has its own NFC mobile phone, but in the main features are different. Apple, for example, has been able to use NFC only for Apple Pay, although it has been powered by an NFC chip since iphone 6, and most of the NFC applications mentioned above are unusable. Samsung Pay is not the only use, and other features can be used with the support of third-party apps. Xiaomi integrates "full-featured NFC" In the system, not only native support for mobile payments, but also the ability to brush with a bus card.

Do you want to try a variety of features with an NFC-enabled phone, or would you like to switch to a mobile phone with NFC? In fact, small part of the view, at present, mobile phone without NFC is not a matter of urgency, after all, the phone is essentially a communication tool, with these features is just icing on the cake. Perhaps after two years of social infrastructure support NFC, it will become the big phone "standard".
