In daily life, we often see and use some QR codes, such as the QR code on train tickets and the QR code of goods. Generally speaking, two-dimensional codes can store a large amount of information, and the information contained in two-dimensional codes can be transferred by scanning. The QR code in WeChat has the same function. By scanning the QR code of a friend's WeChat, you can add the other person as a friend, and then get the relevant information of the other person. In this way, information can be exchanged and transmitted quickly. Most importantly, as a WeChat merchant, the other party can also realize information conversion and transmission in this way, and quickly understand your product information. Take the WeChat QR code as an example. QR codes are generally square. In three corners, we can see the pattern of "Hui". The main function of these three patterns is to locate the decoding software, so that the scanner can read from any angle without aiming at a unique angle. The middle position of the QR code is a square pattern, which can be designed by yourself. After scanning the QR code, the scanner will be directed to the website of the product or service. For example, after scanning the WeChat QR code with your mobile phone, you can directly see the information of the other party's WeChat QR code, so you can easily add the other party as a friend. QR codes have been used since the early 1990s. At present, it will be widely used. Besides wear resistance, degaussing, virus-free and insufficient capacity, it also has the following advantages: high-density coding and large information capacity; Wide coding range; Powerful fault tolerance and error correction function; High decoding reliability; Encryption measures can be introduced; Low cost, easy to manufacture and durable. At present, the penetration rate of smart phones is already very high, almost one person. Therefore, the marketing opportunities of the QR code gradually appears. Through the media, you will feel that many domestic enterprises are using QR code marketing. Walking on the street, you will see QR codes in leaflets, outdoor advertisements, digital media and other places. As a business model, WeChat business can certainly build a bridge with customers in this way. In 200 1 year, a mass supermarket in South Korea integrated advertising modes such as bus stops and subways, and launched the "QR code mobile shopping" activity. Consumers can get a certain discount by scanning the QR code of Lai products with their mobile phones. This method won the favor of many consumers at that time, with sales increasing by 130% and supermarket members increasing by 76%, which can be said to be fame and fortune. In order to facilitate the marketing of WeChat QR code, we conducted such a survey on 500 users using smart phones. Among the 500 respondents, 95% users know the QR code, and men's cognition is higher than that of women. Another 80% people have used QR codes. The channels from high to low for them to obtain QR codes are: WeChat content reprinting, websites, magazines and newspapers. Among these users, the reasons why they scan QR codes are: being interested in content, participating in activities, winning prizes, etc. As can be seen from the above cases and surveys, it is very necessary to use WeChat QR code as a marketing tool in WeChat business, and it is best to lock the age at 22 ~ 45. In the process of application, it is best to add some inducing factors, such as scanning QR code to send gifts and participating in lottery activities. So that users have the impulse and desire to learn more. The popularity of QR codes is due to the popularity of smart phones. It is convenient to scan QR codes with smart phones, and another reason is the popularity of mobile phone networks. Walking in public places, you can always see many people playing with their heads down. If you look closely, most of them are browsing information on the mobile Internet. This shows that the mobile Internet has become very popular. Take China Mobile, China Unicom and China Telecom as examples. Most of their packages contain free traffic. This also promotes people's use of mobile phone networks. Over time, people have developed the habit of using the mobile Internet. Once the user's habit of using the mobile network is formed, the QR code will be placed in front of the user, and the user will take out his mobile phone to scan it, and the QR code marketing will become a popular trend. Therefore, for WeChat merchants, it is a very good way to use QR code for marketing promotion. The design of QR code is very important for QR code marketing in WeChat business. The designed QR code can guide people, otherwise they may turn a blind eye. In this regard, platforms such as WeChat and WeChat official account have detailed tutorials, so I won't repeat them here. The most important thing to do WeChat business is to find prospective customers. Since the main tool for doing WeChat business is mobile phone, consumers and operators are doing it on this tool, then using QR code marketing will give customers a quick entrance.
