What is QR code? How does it work?
You may have noticed the QR code generator tool among our tools, but do you know what a QR code is?
Hello again on our site SProblemes.com . You may have noticed the QR code generator tool among our tools, but do you know what a QR code is? You've probably purchased a product at some point that has that small square filled with scattered dots on its packaging, or you've seen it in roadside ads, magazines, or even web pages... If you're wondering about the purpose of this small square and what it is, you're in the right place.
What is a QR Code?
QR Code stands for Quick Response Code; it means an image composed of points or lines arranged in a digital manner, used to store information about many things in our daily lives. Its use varies from person to person: some use it to distinguish their products from others, while others use it to place links or information to make it easier for users to access. In short, a QR Code is the developed or "second generation" of a Barcode.
Difference between Barcode and QR Code:
- The QR Code can store vast amounts of information, unlike the Barcode which can only store numbers and limited information.
- QR Codes can store many types of information like numbers, letters in all languages, hyperlinks, email addresses, and full contact information.
- QR Codes can be read using a smartphone camera and a small program, whereas Barcodes need special, costly devices only available in stores and post offices.
- They also differ in shape: Barcodes are typically rectangular lines, whereas QR Codes are square and have both horizontal and vertical dimensions.
Uses of QR Code:
QR Codes can be used on many daily items such as food, medicine, electronics, and in advertisements and magazines. Recently, it's also used in designing business cards to store all your information via a QR Code so you don't have to carry the card at all times. Just direct the phone's camera at the code and it saves all your data on the device.
