Xiaomi 6 mobile phone claims to support full-function NFC, and NFC is believed to be familiar to everyone. So, what does Xiaomi's full-function NFC mean? I'll introduce it to you this time. Let's take a look.
Full-featured NFC supports card reading, card writing, card reader, card emulation and P2P mode at the same time. Simply put, it is a mobile phone that can support various NFC functions.
At present, most NFC mobile phones do not support five modes of "card reading, card writing, card reader, card simulation and P2P mode" at the same time, because they are not called full-featured NFC. For example,
Glory V9 supports card simulation, card reader and peer-to-peer mode
Hammer M1L supports card reading, card writing, card simulation and P2P mode
Xiaomi 6.
card emulation is a very important function of NFC, which is the most widely used. Simply put, it can simulate various cards, such as credit cards, access cards, coupons, membership cards and so on.
Peer-to-peer mode and P2P mode actually have the same meaning, but they are written differently. It is used to support the communication between two NFC devices, for example, we can use two mobile phones to transmit some photos or novels to each other (computer Pepsi PC841.COM). Other audio or other devices that support NFC function can enjoy the content by contacting with the mobile phone.
read-write mode, which is widely used in many commercial fields. For example, some advertisements have an NFC sensing area, so you can read the corresponding content when you put your mobile phone on it, such as discount promotion information of goods or a website address. In addition, offline stores also need to use this read-write mode to pay by credit card and withdraw money from banks without a card.
at present, Xiaomi bus card supports as many as 1 regions, including Beijing, Shanghai, Guangzhou, Shenzhen, Wuhan, Suzhou, Hangzhou, Changsha, Jilin and Nantong.
attachment: technical features of nfc
like RFID, NFC information is transmitted by electromagnetic induction coupling in the radio frequency part of the spectrum, but there are still great differences between them. First of all, NFC is a wireless connection technology that provides easy, safe and fast communication, and its transmission range is smaller than RFID. Secondly, NFC is compatible with the existing contactless smart card technology and has become a formal standard supported by more and more major manufacturers. Thirdly, NFC is a short-range connection protocol, which provides easy, safe, fast and automatic communication between various devices. Compared with other connection modes in the wireless world, NFC is a close-range private communication mode.
NFC, infrared and Bluetooth are both non-contact transmission modes, which have different technical characteristics and can be used for various purposes, and their technologies are not different.
The built-in NFC chip of NFC mobile phone increases the function of two-way data transmission compared with RFID, which was originally used only as a tag. This progress makes it more suitable for electronic money payment. Especially RFID can't, mutual authentication, dynamic encryption and one-time key (OTP) can be realized on NFC. NFC technology supports many applications, including mobile payment and transaction, peer-to-peer communication and mobile information access. Through NFC mobile phones, people can connect with the entertainment services and transactions they want at any place, at any time and through any equipment, so as to complete payment and obtain poster information. NFC devices can be used as contactless smart cards, reader-writer terminals of smart cards and device-to-device data transmission links. Their applications can be mainly divided into the following four basic types: payment and ticket purchase, electronic tickets, intelligent media and data exchange and transmission.
