It will be the top priority to ＂brush the face＂ under the 5G tuyere to speed up and increase the temperature to strengthen the security line.

　　A few years ago, "brushing your face" was used by friends to tease each other. In a blink of an eye, eating by "face" has become a reality. Previously, the first smart subway in Guangzhou achieved "brushing face". Under the 5G tuyere, the major payment giants are gearing up, and the payment for brushing their faces begins to speed up.

　　Brush face payment makes people’s lives more convenient.

　　Bus card, change, mobile phone … … You don’t need to bring them all. In Guangzhou, just brush your face by subway! According to media reports, recently, Guangzhou’s first smart subway station was opened, and passengers can brush their faces without feeling the barrier. Face recognition is completed within 300 milliseconds, and 40 people can pass every minute.

　　Guiyang, as an inland capital city, opened the experience scene of subway face-brushing payment to the public as early as this year’s Expo. The general feedback from the public is, "It’s too fast and convenient to brush your face for seconds!"

　　At present, Guiyang is taking advantage of its own big data development to implement the application project of public transportation brush face. It is expected that by the end of 2019, some lines of Guiyang subway and bus will try to pay for brush face. Guiyang will gradually build a face-brushing consumption ecology, and realize "one registration, face brushing in the whole city" in the urban area.

　　I don’t know when it started, but face-brushing payment has penetrated into people’s daily life.

　　Xin Yang, deputy director of the National Engineering Laboratory of Disaster Recovery Technology and professor of Cyberspace Security College of Beijing University of Posts and Telecommunications, said that from the original KFC KPRO restaurant to today’s pharmacies, supermarkets, convenience stores and many other offline retail scenes, more than one million consumers across the country have taken the lead in experiencing the convenience of paying by brushing their faces. At the same time, in the field of "internet plus government affairs", users in more than 170 cities have completed identity verification by brushing their faces, and handled matters such as provident fund withdrawal and tax inquiry online.

　　The era of brush face payment is gradually approaching.

　　"Brush face" under 5G tuyere speeds up and warms up.

　　Up to now, with the advent of the 5G era and the deep integration of technologies such as internet plus, AI intelligence, cloud computing and Internet of Things, the payment for face brushing has started to speed up and warm up.

　　Xinyang believes that compared with scanning code payment, face-brushing payment will bring more convenience to people, such as easy payment in the case of carrying heavy objects; Moreover, due to the superposition of AR capabilities, the payment scenario is more interesting.

　　On the other hand, in the face of increasing labor costs, face-brushing payment can better open up sources and reduce expenses for businesses.

　　The daily workload of a face brushing machine is equivalent to three cashiers. If 10 consumers check out at the same time, the traditional mode takes 56 seconds, while the face brushing only takes 10 seconds.

　　In Xinyang’s view, the greater imagination of face-brushing payment lies in its drainage ability and interactive marketing. "This is a new traffic portal in the future. Before and after payment, merchants can make unlimited extensions, such as combining consumption records and preferences to recommend suitable products to consumers. This is the real value of brush face payment and the future development direction. "

　　Xinyang predicts that Ali and Tencent are spending huge sums of money to promote and research the face-brushing payment technology, and the whole industry has great development prospects. In the next five years, face-brushing payment will show a spurt of growth and reshape the ecology of the entire payment industry and retail catering industry.

　　Strengthening the security line will be the top priority.

　　By uploading your own high-definition photos, you can replace the face of the protagonist in the classic film and television drama clips with your own face and perform with your beloved idol … … A few days ago, an APP called "Face Change" became popular on the Internet, which triggered a network carnival. However, because users need to blink and look up when they change their faces, which is similar to the face information collected when they pay by brushing their faces, the public can’t help but ask: At the moment when face-washing payment is becoming more and more popular, will the small video after "face-changing" fall into the hands of others, will it endanger the security of face-washing payment?

　　Xinyang said that compared with fingerprints and irises, human face is a biological feature with weak privacy, so the threat to citizens’ privacy is particularly worthy of attention when paying for it. "No matter what kind of face recognition technology, it can be cracked. Whether it is worth cracking depends only on the cost and benefits of cracking. "

　　Xinyang said that it is precisely because of the lack of mobile phone that the use of face information becomes easier. In the era of bio-payment opened by face-brushing technology, how to launch a fierce battle of attack and defense against new technologies, minimize the loss of interests of businesses and consumers, and make the security line stronger and stronger will be the top priority for the future development of face-brushing payment.

　　An embarrassing fact is that due to the imperfection of equipment maturity, customer acceptance and payment security, face-brushing payment has not achieved large-scale popularization in China. At present, users prefer to use relatively safe mobile phones to pay. (Correspondent He Chun, reporter He Xinghui)
