QR Code Reader: Scan and Decode Information Instantly

Quick Response (QR) codes have become an essential part of modern technology, bridging the gap between physical and digital interactions. From making online payments to scanning product details and accessing websites, QR codes simplify everyday tasks. A QR Code Reader is a tool or application that scans and interprets these codes, instantly providing the embedded information to the user.

What is a QR Code Reader?

A QR Code Reader is software or a hardware-based scanner that reads QR codes using a device’s camera or a dedicated sensor. Once scanned, it decodes the stored data into human-readable information.

QR Code: A two-dimensional barcode that can store URLs, text, contact details, or payment information.

Reader/Scanner: Translates the pattern of black and white squares into usable data.

For example:

A customer scans a QR code at a restaurant to instantly view the digital menu on their phone.
