What is a QR Code and How to use it?
Hello Friends, today I am going to share with you about the QR Code.
Have you ever seen this type of sign on any magazine or any product you bought at a shop?
The above is sign is called QR code (QR stands for Quick Response). These signs contain digits (encoded text, data, url) which can be scanned only with devices like Smartphones.
A typical barcode can only hold up to 20 digits where as a QR code can hold up to 7000 numeric characters, which makes it easier to pack more information inside a small QR code. But one thing has to be remembered is that if more information is packed inside it, a sign becomes more dense and hence will require a very sensitive device to scan the data accurately.
The advantages of a QR code is that it can contain a lot of information inside a small box. Which mean you can get a complete information about a product by scanning it’s QR code.
