Interpretation of the four application modes of QR code

The application industry of QR codes is very wide and covers all walks of life. However, its application mode currently has four main types, namely, reading data mode, decoding internet mode, decoding verification mode, and decoding communication mode.

This article refers to the address: http://

1. Read data mode

It means that the two-dimensional code is scanned by the mobile phone or two-dimensional code recognition device, and the decoding software displays the data information after decoding, and can directly deposit it with less user input. The most common applications are electronic business cards, traceability of information, and so on.

When making a business card, you can encode the name, phone number, etc. with a 2D barcode and print it in the corner of the business card. When people exchange business cards, they use mobile phones to capture 2D barcode patterns. After decoding, they can store the other party's information in their mobile phone's phone book, omitting the traditional manual entry process, and overcoming the current inaccuracy of business card recognition using business card recognition software. The problem is that it is very convenient to realize electronic data exchange.

It can be derived, write the displayed data information, feed it back to the server, and then send it back to the terminal, print it or store it on the terminal as a voucher or document. For example, when the animal is quarantined, the quarantine officer scans the animal. The code code earmark automatically displays the relevant information of the animal, and then the quarantine officer inputs the quarantine information, sends it to the designated server, the server obtains the data change database, and feeds back to the terminal for printing.

2. Decode the internet mode

Refers to the mobile phone or bar code reading device scanning QR code, showing the link of the relevant URL, the user can access this link for data browsing or data downloading activities. The most basic mode is network information browsing, such as electronic advertising, shopping mall special area information, website information inquiry, e-books, electronic map inquiry and so on.

In the future life, general merchandise, business cards, and even advertisements in newspapers and magazines will be accompanied by corresponding QR codes. The website links will be entered into the QR code. After scanning the 2D barcode with the mobile phone with built-in 2D barcode reading engine. By parsing the URL IP, you can automatically link to the corresponding WAP website, you can directly browse the goods, download discount coupons, use mobile phones to pay for tickets, and so on. It is also easy to experience streaming media information such as ring tones, games, videos, etc. anytime, anywhere, bringing consumers a new mobile Internet mode.

Its derivative mode refers to information download, such as downloading bells, downloading audio samples, downloading coupons, and purchasing electronic tickets.

3. Decoding verification mode

It refers to the QR code of the mobile phone or QR code recognition device, submits the data to the verification server, and the server sends the feedback result back to the mobile phone to verify the validity of the product or service. The most basic application lies in the identification of product anti-counterfeiting information. The derivative model is mostly used in logistics or channel management, and also applied in the payment field for verification of payment certificates. For a long time, counterfeit and shoddy goods have jeopardized the vital interests of enterprises and consumers, seriously affecting the country's economic development. Due to the single anti-counterfeiting technology and anti-counterfeiting methods, ordinary consumers lack factors such as anti-counterfeiting tools, and the anti-counterfeiting effect is not satisfactory.

This problem can be effectively solved by using a mobile phone equipped with a 2D barcode reading engine. The two-dimensional bar code has multiple anti-counterfeiting features, which can be password anti-counterfeiting, software encryption and use of information such as fingerprints, photos, etc. for anti-counterfeiting, so it has strong security and anti-counterfeiting performance. The 2D barcode anti-counterfeiting certification platform introduces both hardware and business-based structures to provide basic information and offline certification. The manufacturer assigns a product code to each piece of the factory product, which is a two-dimensional code assigned to the product according to the corresponding coding standard when the product is produced. And establish a commodity information database to store information about the products that have been shipped. Use the database system as a certification platform for commodity anti-counterfeiting. When a consumer purchases a product, the authenticity of the product can be identified by scanning the two-dimensional code on the product with a mobile phone equipped with a two-dimensional bar code reading engine and querying the manufacturer's product information database. Through this anti-counterfeiting technology, it will greatly promote the maintenance of normal market order.

4. Decoding communication mode

Mainly refers to the form of SMS, email or phone number after decoding, which is mostly used for SMS voting, email contact, telephone consultation or IVR.

  • High light transmittance, uniform mixing effect.
  • High performance LED chip of international class brand.
  • Multi - layer protection ensures a more reliable waterproof performance of lamps.
  • Simple support installation for a wider installation environment.
  • Aluminum alloy bottom structure, surface oxidation treatment, polymer resin package, PC outer cover, use safer;It's more waterproof and durable.The appearance is smooth and beautiful.
