What are QR codes
QR codes (Quick Response codes) are two-dimensional matrix codes that represent a special type of barcode. They were created by the Japanese company Denso Wave in 1994 for use in the automotive industry, but are now widely used in various industries including marketing, advertising, logistics, and more.
QR codes consist of black and white square modules that encode information. They can be quickly and easily scanned using a mobile phone or other device with a camera and corresponding software for reading QR codes.
What data can be encoded in a QR code
QR codes can contain various types of information such as text, URL addresses, contact information, geographic coordinates, Wi-Fi data, and much more. QR codes can also contain encrypted data, making them more secure for transmitting confidential information.
QR codes can also be used to encode information for business purposes such as advertising, marketing, loyalty, inventory management, and more.
QR codes can also be used to encode binary data such as images, sound, video, and other types of files. However, the size and capacity of a QR code may limit the amount of data that can be encoded in a single QR code.

QR Codes for Payments
QR code payment is a method of contactless payment in which payment is made by scanning a QR code from a mobile app. This is more convenient and cheaper than payment using a POS terminal. You can pay for utilities, transportation, hotel accommodation, and other goods and services using QR codes.
QR code payment is implemented differently in different countries and through various applications. For example, in China, QR code payment is much more popular than payment by bank cards, due to its convenience and benefits.
Alternatives to QR Codes
There are various alternatives to QR codes that are also used for encoding and transmitting information:
The choice of alternative depends on the type of information that needs to be transmitted, the purpose of use, technology capabilities, and other factors.
- EAN and UPC barcodes are linear barcodes used to encode digital and alphanumeric data such as product numbers or barcodes in stores.
- Other 2D barcodes such as Data Matrix, MaxiCode, and Aztec Code can also be used to encode large volumes of information.
- Near Field Communication (NFC) tags are electronic tags that use contactless communication technology at close range to transmit data. They are used for mobile payments, identification, and other applications.
- Contactless technologies such as Bluetooth, Wi-Fi, and Radio Frequency Identification (RFID) can also be used for data transmission.
- Encoding information in the form of text or URL addresses can be used for simple applications and online services.
It should be noted that QR code is the most common, simple, and inexpensive way of encoding information. It is widely used in many countries, including Russia.
