The mobile industry is growing at a very fast rate. There was a time when a person had to log into the computer to use the internet. Now things have changed. People are spending more time on phones than on computers because they can browse the internet by turning on the mobile data connection.
As mobile phones are being used by billions of people, companies are now accepting payments from mobile phones with WiFi or NFC technology. Smartphones powered by Android and IOS OS have killed many services which were widely used 10 years back when Nokia was the largest phone brand in the world. The services include SMS, MMS, GSM calls, etc. Most of the revenue of telecom companies come from internet related services.
Barcode use has been stopped by many companies because of the growing popularity of QR codes. Both are old technologies, but QR codes have become more popular because of smartphones. In the coming years, it may completely replace barcodes.
There are several reasons why QR codes are better than barcodes. The major difference between the two is the character limit. QRC can hold around 100 characters whereas BCs have a character limit of 48. The characters are arranged in a matrix (array) format and QR code reader apps can recognize them within 2 to 3 seconds.
QR codes make our lives easier. It isn’t easy to copy or open the website URL on mobile phones. If QR code has been added to the web page, the user can open the URL by scanning the code with a QR code reader application.
QR codes are now being used to verify identity. A good example of this is the desktop version of WhatsApp. When you use the official WhatsApp software on PC, you’ll be asked to verify your account by scanning a QR code.
QRCs are widely used in two-factor authentication and password manager apps for PC and mobile phones. Because of them, the user can log into a web service without entering a password or PIN.
Well, QRCs are being used everywhere. Thus, it’s important to install a QR code reader. Here’s the list of applications you can use to scan and read QR codes.
