The QR code was invented in 1994 by the Japanese company Denso Wave, a subsidiary of Toyota. Originally, the team led by Masahiro Hara developed this technology to track the itinerary of spare parts. They aimed to create a high-capacity barcode capable of storing more information than traditional barcodes. The QR code was designed to be easily readable by scanners and mobile phones, making it a versatile tool for storing and transferring data.
Previously underutilized, the COVID-19 health crisis has given QR code a new lease on life. It has become an essential tool in helping to limit the spread of the virus, facilitating tracking and tracing measures, as well as providing important information to users. It is now widely used in various fields, ranging from advertising and marketing to logistics, product tracking, ticketing, and much more.
QR codes were extensively used to implement contact tracing systems in many countries. Establishments such as restaurants, bars, hotels, and entertainment venues required customers to scan a QR code upon arrival. This enabled health authorities to quickly contact individuals if needed by identifying close contacts.
QR codes were utilized to facilitate the verification of health passes and vaccination certificates. Individuals could scan a QR code with their smartphones to prove their vaccination status or negative test result. This streamlined the verification process when accessing certain venues or events.
QR codes were used to replace physical menus in restaurants and cafes. Customers would scan the code to access the menu on their phones, avoiding the sharing of physical objects and reducing the risk of transmission. It is worth noting that even today, many restaurants continue to use QR codes to share their menus.
QR codes were also employed to provide information and guidance on COVID-19 prevention. Posters containing QR codes were placed in public spaces, public transportation, and offices to redirect users to online resources such as government websites or health organization sites, offering quick and easy access to accurate information. Scanning a QR code to access information has become commonplace instead of receiving a paper document.
QR codes were used to facilitate contactless payments. Mobile payment applications integrated features that allowed scanning merchants' QR codes for quick and easy payments without handling cash or using payment terminals. Many people adopted this payment method and have stuck with it.
QR codes also allow for the dissemination of online questionnaires.
Here are some examples of online questionnairesthat can be distributed through QR codes:
These questionnaires are used to collect the opinions and attitudes of respondents on different subjects. They can cover areas such as customer satisfaction, consumer preferences, political opinions, etc.
Questionnaires can be used to gather evaluations and feedback on specific products, services, or experiences. This can help organizations improve their offerings and better meet the needs of their customers.
Researchers and universities often use online questionnaires to conduct academic studies and collect data from a large sample of participants. This can include surveys on behaviors, attitudes, perceptions, or other specific research areas.
Questionnaires can be used in a professional context to gather evaluations and feedback from employees on various aspects of their work, such as job satisfaction, engagement, performance evaluation, etc.
Event organizers can use online questionnaires to collect feedback and comments from participants. This can help evaluate the success of the ev
It is important to personalize the questionnaire according to your specific objectives and target audience. Make sure to ask clear, precise, and relevant questions to obtain meaningful and actionable responses.
