A QR Code (Quick Response Code) is a type of 2D barcode capable of storing information and allowing instant access by scanning with a smartphone camera or a QR code scanner / QR code reader.
QR codes were first developed in Japan in 1994 and are now widely used worldwide for many purposes such as accessing websites, making digital payments, sharing documents, connecting to WiFi, managing product information, and implementing QR marketing campaigns.
Compared with traditional barcodes, QR codes can store significantly more data and can be scanned faster, even if part of the code is damaged or partially covered.
QR codes can store many types of data. Below are some of the most commonly used QR code types today.
This is the most common type of QR code. When users scan the code, they are redirected directly to a website.
This type of QR code is commonly used to direct customers to a website, marketing landing page, product page, restaurant menu, or online registration form.
A WiFi QR code allows users to connect to a wireless network with a single scan without entering the password manually.
This type of QR code is commonly used in hotels, cafés, restaurants, and offices where visitors need quick access to WiFi.
With one scan, the smartphone will automatically connect to the network.
QR codes can link directly to online documents or files such as PDF documents, user guides, catalogs, or brochures.
This type of QR code is commonly used in events, exhibitions, product marketing campaigns, and educational materials where users need quick access to digital documents.
A vCard QR code allows users to quickly share contact information, including name, phone number, email, website, and address.
People who scan the code can save the contact information directly into their smartphone address book.
This type of QR code allows users to quickly access social platforms such as QR Facebook, QR Instagram, QR TikTok, QR LinkedIn, or QR YouTube.
Businesses often place social media QR codes on product packaging, posters, standees, and business cards to make it easier for customers to connect with their brand online.
Creating a QR code online is very simple and only takes four steps.
Select the type of data you want to encode in the QR code, such as URL, WiFi, text, file, or digital business card.
Enter the information you want to share, such as a website link, WiFi password, contact information, or text content.
You can customize the QR code design by changing the color, adding a logo, or adjusting the shape of the QR code.
After completing the setup, you can create QR code and download it in PNG, SVG, or PDF format for online use or printing.
When you create QR code, you will encounter two common types: static QR codes and dynamic QR codes.
A static QR code stores the information directly inside the QR code itself.
Characteristics include being free to generate, not editable after creation, and suitable for fixed information.
Examples include WiFi access information, text content, or contact details.
A dynamic QR code contains an intermediate link that allows the content to be updated.
Advantages include the ability to edit content after the QR code is created, track scan data using QR analytics and dynamic QR tracking, and support QR marketing campaigns.
Examples include advertising campaigns, marketing landing pages, and event information.
QR codes are used in many industries.
Marketing: QR codes help businesses implement QR marketing campaigns, directing customers to landing pages, mobile applications, or promotional programs.
Retail: In the retail industry, QR codes are used for product traceability, providing product information, and verifying product authenticity.
Restaurants and hotels: QR codes are commonly used for digital menus, payments, and WiFi connections.
