Everything You Need to Know About the QR Code

QR codes; you’ve probably heard of them before and you’ve probably utilised them at some point. They are used in various ways and are one of the most effective forms of barcode for many industries, such as marketing and communications, as well as for stock control within warehouses and factories.

The QR code has been enjoying some well-deserved time in the spotlight recently and, while it seemed to fade away for some time, the prospects are even more exciting. Could this be due to the introduction of QR code payment mark?

So, in a world full of advanced technology, just what is a QR code and could they be making a huge comeback for business, marketing and much more?

What is a QR Code?

QR is short for Quick Response code and is an ‘upgraded’ version of a barcode. Think of a QR code as a custom barcode which can hold more information in less space. These 2D barcodes can store more than 4,000 alphanumeric characters horizontally and vertically. A traditional (linear) barcode can hold roughly 20 characters.

As a machine-readable barcode label, it consists of an array of black and white squares. The information stored in a QR Code is usually URLs, but anything can be stored, from contact data to calendar data, email addresses, phone numbers, SMS opening, plain text and geolocation.

They were originally designed to track cars throughout the manufacturing process; however, they can now be found everywhere from warehouses to assembly lines, business cards and billboards!

How Are QR Codes Made?

Conventional 1D barcodes are mechanically scanned and are read by a physically bouncing narrow beam of light onto the code. This can be interpreted using the pattern of light reflected off the white gaps between the lines. QR Codes are digitally scanned. They are made up of blocks and squares – or pixels – which can be read by an image sensor and interpreted by a system processor. The parts of dots and squares stand for position, alignment, timing, version information, format information, error correction key and an area of a quiet zone. The three evident large squares help the QR reader or barcode scanner to quickly identify and orient the image.

How to Use a QR Code

You can use QR codes in business in many ways, such as business cards, promoting an event and even for business invoices:

  • Business Cards: You can give your customers more than just a ‘regular’ business card with the addition of a QR code. With a QR code, you can include more than just your basic information because they can store more than simple data. You can add links to your website, blog, social media, add photos and much more. One simple scan and all your information can be saved to their contacts.
  • Invoices and Business Stationery: If you include a QR code on items of business stationary or invoices that lead directly to your customer service site, you can provide much more detailed and helpful information such as contact details, user guides, return labels and much more.
  • Inventory Management: QR codes along with other 2D barcodes can be very important tools for manufacturing and inventory management, as you are able to track more than just product name and price. QR codes can also include information such as serial number, part number, lot information, dates and much more data points.
  • Events and Advertisements: When using QR codes for your events or advertising, you can lead the barcode scanner to a virtual version of your event or promotion. You can include e-tickets, directions, maps, handouts, money-off vouchers, and any other relevant information they may need.
