Those who think that near field communication (NFC) is just a mobile payment technology may be surprised to learn that this wireless connection technology is about to change the way we use smartphones and home electronics. Initially, NFC technology was developed and promoted as a technology to ensure the security of mobile payment and ticketing applications. It allows consumers to conduct transactions by simply placing their mobile devices close to NFC-enabled payment terminals.
Various stakeholders are enthusiastic about this mobile payment technology, including credit card companies, mobile operators, smartphone manufacturers, leading mobile operating system developers and banks and financial institutions. The active participation and support of these influential institutions will help promote the growth of mobile wallets and other applications, and promote new e-commerce opportunities.
Because so many stakeholders are willing to help this technology take off, smartphones using NFC technology have gained significant growth momentum. It is estimated that from 2012 to 2015, the shipment of NFC-enabled smartphones will increase by 473%, and the transaction volume will reach 91 billion US dollars. Banks and financial institutions have also invested in NFC technology in order to seize the business opportunities it brings to ensure that this emerging connection technology is applied in the next generation of mobile phones and provide this feature to the lowest possible fee End user.
As NFC technology has matured and is used by more and more mobile devices, the adoption of this technology is becoming more widespread (see figure). This trend greatly simplifies the various connection options in these devices. For end users keen on new electronic experiences, NFC technology will be a real breakthrough.
As a wireless connection technology, NFC technology has deliberately set certain "restrictions" at the beginning of the design. For example, its scope of work is extremely limited (just a few centimeters), making it very difficult for hackers to attack. In addition, its lowest speed data transmission capability helps to use lower power consumption, which is essential for mobile platforms to adopt this technology. However, when integrated with the advanced connection subsystem already in the smartphone, NFC technology adds a more intuitive and ingenious method for wireless connection.
NFC technology only simplifies the use of wireless connections, and its functions are somewhat irrelevant to mobile payment or mobile e-commerce. Today, smartphones are rapidly becoming the main media consumption method for many users. Sandvine's analysis data shows that more than 55% of the video data stream is viewed on devices other than PCs. People are increasingly using mobile phones to download and watch videos, take photos, listen to audio programs, and share these data with other devices and others. Since Wi-Fi and Bluetooth technologies have become the standard configuration of smart phones, their use in TVs and other home electronic products is also growing. Smooth sharing and transmission of data in electronic products and home devices is gradually becoming a reality.
Although these wireless technologies are already ubiquitous, there is still one aspect that is not straightforward when using these technologies, that is, establishing a secure connection. Regardless of which device is used, users often need to scroll through menus and press keys when establishing connection pairs. In addition, the appearance and functions of these menus and buttons have undergone only limited standardization, thereby exacerbating the confusion and frustration of end users when using them. NFC technology allows these systems to interact with users in a more intuitive way.
Users will not have to use the on-screen menu to establish a wireless connection, but only need to hold a smartphone next to another device (such as a digital TV equipped with a wireless device); after a while, security will be established between the two devices Wi-Fi or Bluetooth connection. After the connection is established, the user can watch the transmitted video on the digital TV or transmit the audio to the wireless headset; keep up with the media content, e-mail, and contact information on the PC; or transfer the photos to the tablet.
Just as touch screens have changed the way people interact with mobile phones, Bluetooth technology has transformed the way video game remotes are used, NFC technology will create a new way of connecting smartphones and other electronic devices.
NFC technology simplifies the connection process and improves the user experience, and the realization of this progress is based on the fact that other wireless technologies in smartphones have evolved over the years, and the connected subsystems are increasingly functioning as a whole, and Not a random stack of several chips. In the future, we still need significant innovations to enable Bluetooth and Wi-Fi technologies to work together to ensure that their wireless signals do not interfere with each other, so that more smartphone systems can easily access every function. NFC technology is like glue, bonding the connection subsystems more tightly, so that end users get more convenience.
NFC "simplified connection" technology will expand its functional layout, including a variety of other auxiliary technologies: Wi-Fi, Bluetooth, Wi-Fi Direct, Wi-Fi display technology and Bluetooth Low Energy (BLE) and other technologies.
Interestingly, as these applications and functions continue to evolve, we will see the use of NFC technology go through a complete cycle, as it is beginning to become the enabler of home e-commerce applications. The exciting development trend will be to use the NFC connection subsystem to transform a CE remote control into a home payment terminal. Consumers can pay for anything (from a pizza to a gardening course) by simply placing their smartphone next to the remote control. By combining with other wireless technologies, NFC technology enables end users to use the payment function of the technology without leaving home.
These applications will make NFC technology the most pioneering user interface technology we have seen so far.
Emergency light can be divided into indoor emergency lights and outdoor emergency lights , Indoor Emergency Light and outdoor emergency lights are determined by the protection level of emergency light , general protection level is low can only be applicable to indoor . Indoor emergency lights can be used in commercial buildings , shopping malls , hotels , restaurants , etc .
