Simple, fast and efficient, QR Codes have become one of the most versatile tools.
Whether accessing digital menus in restaurants, event tickets, advertising campaigns or registering in public places, this technology has revolutionized the way we interact with information in our daily lives.
With technological evolution, the use of QR Codes continues to grow, covering everything from access control, interactive marketing to mobile payments, and promises to play an even more relevant role in the future.
But what is a QR Code reader and how does it work? In this article, we explain it in a clear and practical way. Keep reading to find out everything.
First of all, what is QR Code?
QR Code (Quick Response Code) is a type of two-dimensional barcode that can store information compactly.
Created in the 1990s by the Japanese company Denso Wave, the QR Code is capable of storing a variety of information, from URLs and texts to contact data and product details.
How does a QR Code reader work?
A QR Code reader is a device or application that reads and interprets these codes. Its operation is very simple:
1. Image Capture: The reader uses a camera (from a smartphone, tablet or specific device) to capture the image of the QR Code. The camera lens “reads” the code pattern.
2. Decoding: After capturing the image, the player software analyzes the black and white patterns of the QR Code and converts them into data that the code stores.
3. Action: Once decoded, the data is used as per the purpose. For example, if the QR Code contains a link, the reader can automatically redirect it to the associated website. If it contains text, the reader displays the text on the screen.
The use of QR Codes for Access Control
The use of QR Codes for access control is transforming the way we manage entry to buildings, events and other spaces that need to control the flow of people in a digital and automated way.
QR Codes have practical applications in various industries and everyday scenarios:
- Companies: Control of entry of employees and visitors with complete security.
- Residences: Practical and safe access for residents in condominiums
- Events: Quick check-in with digital tickets.
- Vehicle Control: Automation of parking lots with reading QR Codes for vehicles.
Main advantages
Improved Security
QR Codes are uniquely generated and can be configured to be used once or to expire after a certain period, preventing misuse.
Ease of Use
Without the need for physical keys or cards, access is simplified. Users can present the QR Code directly on their cell phone, reducing the risk of loss or theft of access credentials.
Automation and Efficiency
This method allows for the automation of the access control process, reducing the need for manual supervision and increasing efficiency. It can be integrated into monitoring systems, recording inputs and outputs and even alarm systems.
Flexibility
It can be used in different contexts, from offices and companies to events, parking lots, gyms or restricted areas in factories and warehouses.
