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 have started to spend more time on their phones than on computers because they can easily browse the internet by enabling a 4G, 3G or GPRS connection.
As mobile phones are being used by more than 50% people in the world, companies have started to accept payments from mobile phones with WiFi or NFC technology.
Smartphones with Android and IOS 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.
Bar code 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 bar codes.
There are several reasons why QR codes are better than bar codes. The major difference between the two is the character limit. QRC can hold around 100 characters where’s BCs have a character limit of 48. The characters are arranged in a matrix (array) format and they can be easily read by a QR code reader app.
QR codes make our work easier. Many users find it confusing to copy or open website URL on mobile phones. If QR code has been added to the web page, the user can easily 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 apps for PCs as well as mobile phones. Because of them, the user can log into a web service easily as the password will be generated on the fly.
