Behind Apple Pay with Alipay, behind the topic, there are NFC and QR code for many years of expedition. More specifically, the near-field communication and graphical code (including two-dimensional code, barcode, etc.).
The two-dimensional code is encoded with "0", "1" with a specific arrangement. Information can be output to the network via an image input device or a photoelectric scan device. Although the read slow, single-direction, bearer is small, but the cost is low, the reproducibility is strong, often used as a one-way read credential, identity identification mark.
NFC is evolved from high frequency wireless communication technology to transmit data through near-field RF signals. Although the cost is high, the data can be transmitted in two-way communication, high readiness, high security, and a variety of ways such as card and equipment, equipment and equipment (card card mode are read, the card mode is read, point-to-point mode It is interaction), wide application range, such as access control, payment.
Many analysts believe that NFC prospects are better, especially with mobile payment, is very fit - non-contact, fast, safe. In addition to mobile payment, bus card, data transmission, new train ticket, boarding pass, access control, etc. can be achieved by NFC technology. It seems that NFC is the future of intelligent life.
In fact, whether it is the application of NFC on payment, or two-dimensional code in payment, voucher applications, is just a horn of iceberg. Their larger application is to provide a solution for the connection of the Internet of Things.
Is it a wrong direction?
The Internet of Things expands "information exchange and communication" in the Internet, and is considered to be an important part of the new generation of information technology after the Internet and mobile Internet.
In the past few years, technology companies have realized the arrival of the Internet of Things. Google, Apple and Samsung are all developing products around these platforms around these platforms.
However, the Internet of Things has been sang a few years, but it has been not warm. In this regard, the father of Android is directly represented: the development of the Internet of Things is reversed. The ecosystem is used to support the popular equipment, and there should be an apparatus before, and then there is an ecosystem.
Very Very Very Very Very Very Very Very Very Very Very Very Very Very Very Very Very, China's intelligent hardware entrepreneurial companies have developed in China than the US, and the "intelligent hardware" has developed in full swing. A large number of Internet big brothers such as Alibaba, Tencent, Jingdong bring huge sums of money, and push the entire intelligent hardware industry to the air.
In particular, the typical circle of the Internet of Things - the development of smart home is more wind, a large environmental monitor (CO2, temperature and humidity, formaldehyde, etc.), air purifier, water purifier, smart door lock, intelligent large electrical appliance , Smart socket, cloud camera, routing, set-top box appeared in the crowdfunding website. But it seems that there is always a lot of strength.
For example, almost all small intelligent hardware use Bluetooth to connect to the phone, transfer data. This phenomenon always makes me doubt my awareness. Is someone else's mobile phone to connect to several Bluetooth devices at the same time? Is someone else's mobile phone low-power blue tooth? Is it basically not charged? Is the mobile phone is the only data acquisition device?
Fortunately, there are some intelligent hardware connecting WiFi. I no longer need to turn on Bluetooth, but it is necessary to connect to WiFi to the cloud to view the data of the front device.
Is there a two-way communication?
In the logistics, the barcode gave the unique identity of the goods. The information of the transceiver, the contact and other information are tied together with this unique identity and recorded to the cloud. The cargo is transported, where the location can be scanned or viewed by scanning this unique identity.
In a pass, registered card, payment, order voucher (movie ticket, take-away order, etc.), the QR code is also used as an identity.
With the cloud, a coded graphic (bar code or two-dimensional code) has information output capabilities, making the Internet of Things.
More than this, MIT's mad researchers have developed an ITORT in the REALITY EDITOR (Real Editor). Specially designed QR code as the identity of the intelligent device, the mobile phone camera as a QR code scanner and connector. With the cloud, users can connect a function of a smart device or smart device like a mobile phone screen. For example, connect your bed with the air conditioning system of the car. To ensure that you have to go to work, the temperature sitting in the car is just right.
Is the connection between the objects and things in the Internet of Things a certain time?
Taking the sports bracelet as an example, the resulting movement data, sleep data does not need to be updated to the phone or cloud. Transferring data through NFC not only increases his hand ring, but also saves the Bluetooth port of the phone.
Smart bottle, smart glass, smart scales, etc. don't need frequent data transmission, and there is a need for cheap and low-energy NFC functions.
NFC also has the function of identifying identity, plus security, quick connection, fast disconnection, is suitable for applications, access control. In the case of the Internet, it is necessary to connect a new device at any time. This fast and reliable connection method will become the advantage of NFC highlight, which is Bluetooth, WiFi can't match.
Naturally, some devices need to be connected to the cloud or mobile phone. For example, most smart home equipment - WIFI (ZigBee or more advantageous connection methods) is a good choice. For example, it is necessary to push the message, which reminds the user's smart watch.
Since the smart watch itself is wearing, raising the feature of hand, making it an opportunity to become the center of the Internet of Things. Now smart watch has started supporting WiFi in addition to support Bluetooth, such as MOTO 360, TiCwatch. Although there is not much support in software applications, this has been thought of this. In the future, the watch supports NFC function more common. Based on such a multi-connection component, it is also very imagined in the future.
Imagine, raise your hand to say a word, you can control a variety of smart home, this is being implemented. It is understood that the domestic smart watch TiCwatch has cooperated with Broadlink (Bolian) to control home appliances with a watch.
In addition, functions such as graphical code payment, QR code board (credentials) can also be easily integrated into smart watches. Alipay's complete offline payment has been implemented in TiCwatch (no mobile phone, no network).
Said so much, people are still anxious to be NFC's penetration rate in China. In Japan, the consumption of mobile phone NFC function is often very common - an apple pay's online trace report that is subjected to a media. 5 years later, a smartphone does not have NFC just like there is no WiFi, it is a solution.
