Although they may seem like a recent invention, QR codes have been around for over 25 years. The QR, or ‘Quick Response’ code, is an evolution of the standard barcode but allows for faster data interpretation and significantly greater storage capacity.
A typical barcode (UPC) used in shops contains a 12-digit number relevant to a specific product or item. In contrast, a QR code can hold a much larger amount of data – up to 7,089 numbers or 4,296 letters. However, when printing QR codes, their scan-ability depends on a combination of factors: the physical size of the code, the print quality (DPI), and the density of the information stored within it.
A QR code can be used for something as simple as storing a website URL or asset number, but it can also contain complex data, such as detailed product information, servicing history, or even automated data feeds into an application. When scanned, a computer identifies three large squares in the QR code’s design to determine its orientation.
This means the code can be scanned from any angle, even upside down. The correct orientation features squares in the top-left, top-right, and bottom-left corners, with the bottom-right corner left empty. The rest of the QR code consists of a matrix of smaller squares, which are scanned both horizontally and vertically (unlike standard barcodes, which are scanned in only one direction).
Most modern smartphones, including all devices running up-to-date versions of iOS and Android, have built-in QR code scanners integrated into their camera applications. Additionally, users can scan a QR code from an existing photograph by simply selecting the relevant area in the image. At Custom Labels Ltd, we print thousands of QR-coded labels daily and have extensive experience in this field, positioning ourselves as one of the UK’s market leaders.
How QR Codes Can Be Used on Labels
QR codes can be incorporated into labels for a wide variety of applications. Here are a few examples:
- Asset Labels: A simple asset label may feature just an asset number, which can then be quickly and reliably scanned into a database, eliminating the need for manual data entry and reducing the risk of human error.
- Contact Labels: These typically display a business’s telephone number, email address, and physical address for advertising purposes. A QR code can be added to direct users to the company’s website or automatically open an email client with a pre-filled sales enquiry.
- Equipment & Rental Tags: For example, a QR code on a heavy-duty piece of rental equipment, such as a power tool, could link to a video tutorial explaining safe usage. It could also provide relevant environmental information, such as fuel efficiency and emissions data, which may be legally required in certain cases.
