How QR codes are revolutionising customer service

QR codes offer a variety of interaction possibilities. The redirection to a website is by no means all that the black/white pixel structure for scanning with mobile devices has to offer. The encrypted codes open up completely new possibilities when it comes to optimising customer experiences and expanding service offers. The enormous potential of areas of application becomes clear when one realises that QR codes not only create a connection between offline and online platforms, but also between different online offers. In addition, almost 50% of people worldwide own a smartphone, which makes addressing them via this service a successful magnet.

What are QR codes and how do they work?

The abbreviation QR stands for “quick response”. The name is deserved because the information can be retrieved within seconds when scanned. Quick Response is a two-dimensional version of a barcode that can be used to transmit large amounts of information.
Each QR code consists of a pattern of black and white dots and lines in a square shape. This structure can store up to 7,089 digits or 4,296 characters (including punctuation and special characters) and images of up to 2953 bytes. This means that each generated pattern encodes diverse content and information individually. In a QR code generator, the structures are created so that the information is embedded multiple times. This way, they remain readable even if they are partially destroyed or covered. This makes the QR code very reliable as an information carrier and service provider.

What can QR codes be used for?

The practical codes are used wherever data needs to be read quickly (e.g. digital tickets) or to help the user bridge the gap between the analogue world (e.g. QR code display in a magazine) and the digital world (e.g. website). The most popular data transfers include:

  • URL: A web page opens in the browser.
  • App Store: This is followed by a direct link to download the application from the App Store.
  • Social Media: The link leads to the corresponding social media profile.
  • Email: Via the scan, an e-mail can be sent directly to the stored recipient.
  • PDF: The deposited PDF file is downloaded and displayed.
  • Text: A static text is displayed.
  • Picture: A picture opens.
  • Video: A video or a playlist opens.
  • Electronic business card: The stored contact data is displayed and is available for direct contact or for transfer to the address book.
  • Geographical location: A location is displayed in Google Maps.
  • Wi-Fi: A connection to the local Wi-Fi network is established.

Show your customers that they and their opinion are important to you and use the given feedback for your business.
