Four main application modes of QR code
The application industry of two-dimensional codes is very wide, involving all walks of life. However, there are currently four main application modes, which are data reading mode, decoding internet mode, decoding verification mode, and decoding communication mode.
1. Data reading mode: refers to scanning the QR code through a mobile phone or QR code recognition device, and decoding the software to display the data information after decoding. With less user input, it can be directly stored. The most common applications are electronic business cards, information traceability and so on.
When making a business card, you can encode the name, phone and other information with a two-dimensional barcode and print it on the corner of the business card. When people exchange business cards, they use their mobile phones to shoot two-dimensional bar code patterns, and 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 inaccurate identification of business cards using business card recognition software The problem is that electronic data exchange can be realized, which is very convenient.
It can be derived, write the displayed data information, feed it back to the server, and then send it back to the terminal, print or store it on the terminal, as a voucher or document, for example, when animal epidemic prevention, the quarantine officer scans the two The dimension code ear tag automatically displays the relevant information of the animal, and then the quarantine officer enters the quarantine information, sends it to the designated server, the server obtains the data change database, and feeds it back to the terminal for printing.
2. Decoding internet mode: refers to the QR code scanned by mobile phone or bar code reading device, displaying the link of the relevant URL, and the user can access this link to conduct 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 query, e-books, electronic map query, etc.
In future life, general merchandise, business cards and even advertisements in newspapers and magazines will be accompanied by corresponding QR codes. The website link is entered into the QR code. People scan the QR code with a mobile phone with a built-in 2D barcode reading engine , Parsing the IP address of the website, 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, etc. You can also easily experience streaming media information such as ringtones, games, videos, etc. anytime, anywhere, bringing consumers a brand new mobile Internet mode.
Its derivative mode refers to information download, such as bell download, audio sample download, coupon download, electronic ticket purchase, etc.
3. Decoding verification mode: Refers to the mobile phone or QR code recognition device to scan the QR code, submit the data to the verification server, and the server sends the feedback result back to the mobile phone to verify the effectiveness of the product or service. The most basic application is the identification of product anti-counterfeiting information. Derivative models are mostly used in logistics or channel management, and are also used in the field of payment to verify payment vouchers. For a long time, counterfeit and shoddy goods endangered the vital interests of enterprises and consumers, and seriously affected the economic development of the country. Due to the single anti-counterfeiting technology and anti-counterfeiting methods, ordinary consumers lack anti-counterfeiting tools and other factors, the anti-counterfeiting effect is not ideal.
Using a mobile phone with a two-dimensional barcode reading engine installed can effectively solve the above problems. The two-dimensional barcode has multiple anti-counterfeiting features. It can use password anti-counterfeiting, software encryption, and use the contained information such as fingerprints, photos, etc. for anti-counterfeiting, so it has extremely strong security anti-counterfeiting performance. The two-dimensional barcode anti-counterfeiting authentication platform introduces both hardware and business-based structures to provide basic information and offline authentication of commodities. The manufacturer assigns a product code to each product that leaves the factory. The product code 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 the relevant information of the products that have been shipped. Use the database system as the authentication platform for anti-counterfeit products. When consumers buy a product, they can scan the QR code on the product with a mobile phone equipped with a two-dimensional barcode reading engine and query the manufacturer's commodity information database to identify the authenticity of the product. 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 displaying the result of decoding as SMS, email or phone number, which is mostly used for business forms such as SMS voting, email contact, telephone consultation or IVR.
A Main Distribution Frame (MDF) is a signal distribution frame or cable rack used in telephony to interconnect and manage telecommunication wiring between itself and any number of intermediate distribution frames and cabling from the telephony network it supports.
