Two-dimensional (2D) barcodes incorporate rectangles, dots, hexagons, and other geometric patterns to form scannable squares and rectangles. 2D barcodes hold a great deal of information and data because they store information horizontally and vertically; in fact, 2D barcodes can store up to 7,089 characters, which is a much greater storage capacity than the 20-character capacity of standard barcodes. 2D barcodes are used in manufacturing, warehousing, logistics, and healthcare, and they are popular because they are legible when printed in small sizes and when etched onto a product.
The mostly used 2D barcodes are QR ,DM,PDF417 in different industries ,here are more details of its applications:
1:Application in Manufacturing Information Management System
In modern industrial production, only the production data, personnel information, and quality information are collected in real time. The management information system can issue instructions to the materials management, production scheduling, quality assurance, and planning and finance systems based on the collected data and time. Therefore, the effective dynamic configuration of personnel, equipment, materials and other resources, at the same time generate various statistical and accounting information, to provide an effective basis for managers to make decisions. Therefore, accurate, fast and timely data collection has become a key link to improve the level of enterprise information system management system, and is also an important content of full implementation of ERP technology. QR code has high information density, strong anti-loss capability and low price. And so on, therefore, in the process of enterprise implementation of ERP, through the use of two-dimensional code technology, accurate, fast and timely data collection can be realized, and the information management level of enterprises can be improved.
2:Application in jewelry inspection and sales management
As a new information storage, transmission and recognition technology, the QR code has the advantages of high reliability, strong security, large information capacity, low production cost, and can represent various information such as Chinese characters and images. Applying the QR code to the jewelry inspection mark can fully utilize its technical characteristics to meet the needs of today's jewelry inspection technology management, and can achieve the following objectives:
a. Store the characteristics of jewelry, such as photos, in a two-dimensional code to prevent the forgery of the inspection mark and improve the anti-counterfeiting ability and image value of the logo;
b. Facilitate the sales management of jewelry through the automatic entry of information;
c. When the consumer purchases, he can inquire the carrying information on the logo to enhance the credibility of the product quality;
d. By establishing a network monitoring and management system, the quality inspection organization can realize the tracking and management of the whole process of inspection, sales and supervision of jewelry, and regulate the sales market;
e. Use the QR code in the quality inspection report and the original inspection record to improve the level of the quality management organization's management files.
3:Application in train and flight ticket management
What applications have the 2D barcodes anti-counterfeiting technology applied to the ticket management system?
a. Ticket security. According to the type of ticket purchased by the passenger, the ticket seller uses the two-dimensional code making software to generate the two-dimensional code and put it on the ticket face of the ticket according to the information (such as the number of times, price, place of sale, etc.).
b. Automatic ticket checking. (1) Checking in the entrance ticket, the ticket checking personnel will recognize and read the two-dimensional code on the ticket through the handheld two-dimensional code recognition device, and the system will automatically identify the authenticity on the ticket and store the corresponding information into the system. (2) On the vehicle, the ticket inspector uses the handheld two-dimensional code recognition device to read the two-dimensional code on the ticket, and the device automatically compares the read information with the data in the database to discriminate the authenticity of the ticket. The use of two-dimensional code reading equipment to check the ticket not only improves work efficiency, but also avoids human error.
c. Scientific management. The railway management department only needs to know the current number of passengers and the corresponding passenger ticket number of each train through the query statistics of the data. It can be easily found through the comparison between the information of the passengers in the system and the ticket sales. Is there a fake ticket ride?
4:Application in mobile payment
Recently, Alipay announced the launch of the QR code collection service. All Alipay users can receive the QR code for “pay me” for free. Consumers only need to open the scanning function of the mobile client and take the QR code. Go to the payment page. After the payment is successful, the payee will receive the SMS and client notification. In Fuzhou, a Warwick taxi company opened Alipay. After taking a taxi to the destination, the customer took out the mobile phone and scanned the QR code car in the car. The mobile phone automatically jumped to the payment page and then followed the car on the meter. The fee is entered, and the entire payment process takes only 20 seconds. At Starbucks, you can bind your prepaid card to your mobile phone and pay for it quickly by scanning the QR code. You don't have to pay long queues.
5:Application in hospital
For the patient, the most annoying thing is to register. With the two-dimensional code, the patient can make an appointment through the mobile phone terminal, and go to the hospital to take the number directly at the scheduled time with the QR code, which reduces the queue registration and waiting time. The QR code service not only solves the problem of registration, but also integrates the two-dimensional code into the process of medical treatment, payment, etc., and can realize one-stop service of medical treatment, payment, and medicine, and no longer allows patients to repeat the queue. In addition, it is also possible to evaluate the medical ethics, and both doctors and patients can strengthen communication and understanding. At present, large hospitals in many cities have adopted at least bar codes. Compared with the past, the level of medical informatization has been greatly improved, and the efficiency of hospital operation has been greatly improved.
