NFC technology to bring mobile phone access control system imagination
Mobile phones are essential personal belongings, gradually replacing the original objects of life, including keys, access control cards, credit cards, tickets ... ... and so on. How can NFC technology be used in human life through portable devices? Near Field Communication (NFC) is actually not a new technology, but recent application-related issues are more and more, especially the topic of third-party payment has been heated up, occasionally we are suddenly concerned that mobile phones In the case of non-contact machines to mutual induction and achieve the purpose of payment, is the use of NFC technology, the most typical example is the bus card. What is the NFC technology and its application level where? What is the reason for the development of NFC? NFC evolved from the combination of Radio Frequency Identification (RFID) and Internet technology, which is a development from the non-contact technology and RFID technology. It is a short Distance wireless communication technology standard. NFC technology to bring mobile phone access control system imagination The basic application of NFC technology can be divided into the following four categories: Access, such as access control, tickets and tickets, allows users to bring their mobile device with a ticket or door code close to the reader. Contact confirmation, such as mobile payment, the user by entering the password or just accept the transaction, confirm the transaction. Contact connection, such as the two built-in NFC devices connected to peer-to-peer data transmission, such as downloading music, pictures and other information exchange and exchange of books simultaneously. Touch browsing, a built-in NFC device can seamlessly browse information stored in another NFC-enabled device. At present, NFC is widely used in mobile phones. It is not new to use mobile phones to sense other devices to achieve wireless transmission. However, since mobile phones are an indispensable item for modern people, more and more applications extend from mobile phones equipped with NFC functions The more extensive. Talk about the category of intelligent buildings, NFC applications currently on the access control system what? Digitizing an access card (becoming a digital certificate) can be easily and securely sent to a given user's cell phone or other mobile device, managing the life cycle of the digital certificate through mobile networks and the cloud, for example, temporary work today Personnel need to enter and leave the building, the management unit can send a "temporary" access control voucher to these staff, when set a good time, the access control voucher will lapse, the safety is no doubt. With the popularity of NFC, digital door-cards / vouchers can be pre-loaded or downloaded into cell phones, or attached to a cell phone or wallet with just one NFC tag. When users open the door with an NFC phone, they can simply touch with a cell phone Access control is like a traditional door card. At present, many European hotels have adopted NFC door locks. The hotel will send the NFC key to guests' cell phones before check-in, and guests will be able to open their mobile phones directly to the designated room on the day of booking. To the counter check-in. We can even foresee that in the near future, NFC will make access control disappear on the door. Users simply touch the NFC tag on the phone and the system will place the door's location (or ID) and the user's credentials and visitors The combination of location, used as a request to the access control system to open the door. Furthermore, the administrator of the access control system may also change the door card with different functions at any time through NFC mobile phones to send different levels of commands to the access control system under different crisis conditions to lock access or release areas of an area Access to divert the crowds. NFC future will have what kind of development trend? NFC has been slowly integrated into a part of the Internet Of Things (IOT) world by a single technology and application. IoT refers to a variety of items connected to the network, ranging from smart thermostats, garage doors, small toothbrushes, heartbeats, and even interior furnishings and light bulbs. The IoT system collects data related to user habits and usage patterns, connects to an application (APP), and then provides cloud or big data server for data analysis to improve the quality of life of the user, and can even provide the product The use and consumption of information to manufacturers to predict consumer demand and improve product quality. NFC, as a starter and initiator of connections, plays an important role in helping devices or sensors to pair instantly to a Bluetooth or WIFI device in a mobile device. Of course, NFC's most important payment functions are also Google Wallet and Apple Pay. However, the potential problems and challenges of NFC are how to improve its security without reducing or affecting the user experience. As any technology matures, we actually see fewer opportunities for it, because it is embedded in different technologies and applications and then everywhere.
