Hello, everyone. The meeting will answer your questions. My payment code has been photographed. Can others use it? can I use it when it is photographed? many people don't know it yet. Now let's take a look at it.

Answer:

1. The Wechat payment code is photographed and cannot be used; because it is useless, you need to enter the payment password to make the payment, and even if you scan it, you need to enter the correct payment password; moreover, the Wechat payment code expires in 3 minutes; the received QR code is dynamic, and the generated QR code will expire automatically after 3 minutes. If the operation cannot be completed, the QR code must be regenerated.

2. The development direction of QR code:

3. The popularity of smartphones and tablets has given birth to previously unpopular QR code applications, and everyone is scrambling to invest a lot of resources in technology research and development. The QR code is the entrance to the mobile Internet; the application of the QR code seems to have penetrated into all aspects of our lives overnight, such as subway advertisements, newspapers, train tickets, air tickets, fast food restaurants, cinemas, group buying websites and various commodity packaging, Ma said. As a part of the Internet of things industry, the application of QR code has never been paid so much attention. Some experts even predict that there will be hundreds of billions of market space in two or three years. The application of the Internet of things is inseparable from automatic identification. Bar code, QR code and RFID are commonly used by people. Compared with the one-dimensional code, the two-dimensional code has the characteristics of large data storage and good confidentiality, and can be better combined with mobile terminals such as smart phones to form better interaction and user experience. Compared with radio frequency identification, QR code not only has outstanding cost advantages, but also has a better application prospect in user experience and interaction. In the mobile Internet business model, people's business activities are more extensive, so it is more necessary to exchange and share information in time. With the popularity of smartphones and tablets in the 3G/4G mobile network environment, the application of QR codes is no longer limited by time and space and hardware devices. Product basic attributes, pictures, sound, text, fingerprints and other digital information can be coded and bundled, suitable for product quality and safety traceability, logistics warehousing, product promotion, business meetings, identity, material document identification and so on. Through the mobile network, we can achieve timely tracking and traceability of material circulation; assist in remote maintenance and maintenance of equipment; anti-counterfeiting and anti-channeling of products and incentives to end consumers; business supply chain process reengineering and so on. Further improve customer response ability and extend products and services to end customers; manufacturers can also grasp market trends in time, develop more practical products to meet customer needs, and finally achieve order-to-order production, which will greatly reduce production costs and operating costs With the vigorous development of the domestic Internet of things industry, it is believed that more application solutions of QR code technology have been developed and applied to the daily business life of various industries, then the QR code will become the entrance to the mobile Internet.
