QR code for your business

The use of QR codes is growing rapidly all over the world. It has become a favorite tool of marketers to woo customers who don’t want to wait for anything. If you are wondering how QR codes can benefit your business, we have the right answers for you. 

In this post, we will take a closer look at QR codes and how they work. Then we will discuss some use cases and industries where QR codes have brought immense change and growth. 

What is QR Code & How does It Work?

QR codes are a subset of barcodes and refer to Quick Response Code. The technology was first introduced in Japan by a subsidiary of Toyota called Denso Wave. QR codes can hold more information and advanced features compared to barcodes and can be programmed to perform various actions. QR codes contain information both vertically and horizontally and can be read through a camera-enabled device like a smartphone. 

QR codes need two basic technologies to work-

QR code generators: You can find many online sites to generate QR codes for free. The QR codes can carry any information you like including product details, offers, coupons and more. You can also program the QR code to automatically initiate various actions like dialing a number, directing to a URL, sending SMS and so on. 

QR code scanner: You will need a device to scan and decode the information in a QR code. iPhones and Android smartphones and tablets are ideal to do the job. You just need to download a QR code reading app, most of which come for free. 

The QR scanner app will scan the QR code using the camera of your phone or tablet. Then it will display the information or perform the action which was programmed into the code. 

QR code offers a simple and quick way to provide information to your customers. You can also save their work by programming QR codes to carry out various tasks like making online payments, viewing transport schedules and more. The technology which has its roots in Japan is now revolutionizing businesses all over the world.

Difference between QR Code and Barcode

  • QR code is a type of barcode. QR codes contain information in a 2D way, whereas barcodes utilize 1D track. QR codes are faster and more reliable than barcodes as you can scan them in two dimensions. 
  • QR codes also take up less space than barcodes. QR also offers 360-degree readability for added convenience. You can scan QR codes from any angle, which is not possible in the case of barcodes. 
  • You can also effectively scan a QR code even if it’s damaged or covered by dirt. The technology offers an error margin of 7% to 30%, which is not applicable for barcodes.

Useful Applications of QR Codes

As you already know, you can create QR codes to perform a wide range of tasks. Here are some common use cases for QR codes-

1 Direct Users to a URL or Landing Page

You can embed the URL of landing pages or sign up forms in your QR code. A user is directed to the URL the moment he scans the code with a QR code scanner. This way, users don’t have to remember URLs or even type them in the address bar. Everything is done automatically!

2 Dial a Number

QR codes are ideal for displaying your business contact information. Your customers can scan the code and get your phone number, address, or any other details you want.

Various leading brands have already used the technique including Snapchat, Angry Birds and Spotify. In the case of Spotify, the QR codes enable users to share or recommend songs. 

4 Lock and Unlock Devices and Equipment

You can use QR codes to allow users to lock or unlock devices and equipment. For example, the cycle rental service Pedl from ZoomCar uses the same technology to lock and unlock cycles. The user scans the code using their smartphone, which then automatically unlocks the cycle for use. 

5 Send Messages and Emails

You can use QR codes to send emails or SMS to your customers. This provides a simple way to track the conversions of your SMS or email marketing campaigns. You can use the SMS feature for opt-in SMS registration, customer support, sales and more.
