Which domestic smartphone is equipped with the most complete NFC function?

Now many domestic high-end mobile phones support NFC, including Xiaomi 9, Huawei P30, iQOO and vivo.

X27 Pro、OPPO

NFC such as Reno has three main functions: instead of bank card payment, instead of bus card, instead of access card. Xiaomi, Huawei, vivo and OPPO all support the above functions, but there are some differences in some details.

Xiaomi and Huawei support more types of bus cards. Because Xiaomi and Huawei's mobile phones supported NFC earlier, and the two companies began to cooperate with public transport systems all over the country a few years ago, the NFC bus cards of these two brands support more areas. At present, Xiaomi NFC bus card supports Beijing-Tianjin-Hebei interconnection card 160 city, Shanghai bus card, Jiangsu traffic card, Suzhou 13 city and Lingnantong 19 city.

And shenzhen tong, wuhan tong (7 places), Hefei Tong, Jilin Tong (6 places), guangxi traffic One Card (14 places), Changsha (2 places), Greentown Tong, Harbin City Tong, Qindao Tong and Hainan One Card (4 places). A total of 23 1 cities and regions can use Xiaomi's NFC bus card. The following figure shows the support scope of Xiaomi bus card:

There are also many areas supported by Huawei bus cards, including Beijing-Tianjin-Hebei Interconnection Card (160 cities), Shanghai Bus Card, Lingnantong (19), Shenzhen Communications, wuhan tong, Changsha, Jiangsu Unicard Suzhou, Tianjin City Card, Guangxi Unicard, Hebei Unicard, Jilin Tong and Jiangsu Unicard Jinling Tong. In total, more than 200 cities support Huawei NFC bus cards. The following figure shows the scope supported by Huawei bus card:

Therefore, the number of cities supported by Xiaomi and Huawei bus cards is similar, but there are some subtle differences. Vivo and OPPO only started to set foot in the field of bus cards last year, so there are not as many cities that can be supported as Xiaomi and Huawei. The cities supported by vivo and OPPO bus cards are mainly concentrated in Beijing-Tianjin-Hebei one-card and Lingnantong, wuhan tong, shenzhen tong, etc., about 160 cities.

Xiaomi and Huawei support bus card transfer. One function that is easily overlooked when using NFC bus card is bus card transfer. After all, this thing has only been around for two or three years. Many users may not consider the need to transfer cards when opening them. However, with the retirement of the first batch of NFC phones, more and more users began to pay attention to this issue.

At present, some models of Xiaomi and Huawei have begun to support the migration of bus cards. When users change their mobile phones, they can transfer the unused bus cards to their new phones. However, there are few types of mobile phones and bus cards that support migration, and their functions need to be further improved. For example, the wuhan tong I use does not support migration, and I have to re-open the card to change my mobile phone, which is very distressing.

On the contrary, Apple's iPhone is doing better. Card information is bound to iCloud. Changing the machine is directly equivalent to changing the card, and it can also be used on Apple Watch. Apple's NFC supports relatively few cities, and it can only be used in Beijing, Shanghai and other places at present, and will support interconnection cards such as Lingnantong in the future.

Access cards have similar functions. The latest NFC phones of Xiaomi, Huawei, vivo and OPPO all support the access card simulation function. This function was exaggerated when the manufacturer publicized it, as if it could replace all access cards. But at present, the access cards of most communities and companies are encrypted cards. There is no way to copy this encrypted card through the existing card. You can only go to the property management department of the company and the community to let the technicians write the card information directly on the mobile phone to replace the encrypted card. In this regard, the NFC functions of Xiaomi, Huawei, vivo and OPPO are all half a catty.

Generally speaking, the main function of mobile phone NFC is to be used as a bus card. In this regard, Xiaomi and Huawei support more cities because they did it earlier. Vivo and OPPO are also catching up, and the speed is very fast. As for bank card payment and access card, the performance of the four companies is similar.
