QR codes provide a seamless transition from the physical world to digital spaces or across digital channels. QR codes have a lower interaction cost than typing in a URL, but convenience does not guarantee that users will take action just because a QR code is presented to them.
Uses For QR Codes
Progressive disclosure. QR codes can provide access to additional information that does not fit in limited spaces or is not relevant to all users. They can be like Learn more links for the physical world. For example, a small sign promoting a local initiative can’t fit much information on it, but more details can be accessed online by scanning a QR code in the corner of the sign. Very few users will take time to scan such codes because they lack interest or the interaction cost is too high, but the code allows the designer to design a simpler sign. The number of scans for this code can reveal meaningful insights about interest in the initiative.
Transitions across different interaction channels. Most often, these transitions are from the physical to the digital space. For example, a parking meter presents a QR code that allows users to download the application for making a payment. In other cases, QR codes can support seamless transitions across digital devices like smartphones, computers, and TVs. For example, passkeys and other forms of authentication. These codes are for convenience, not awareness, so the number of scans the code receives is far less meaningful than the usability of the workflow the code affords. Use qualitative usability testing to evaluate how well these codes perform.
Reducing print needs. QR codes provide a way to move printed information to a digital space. This offers cleanliness, convenience, and benefits for the environment. For example, providing a QR code that links to a restaurant menu reduces the spread of germs and the need for printing menus while allowing as many people to access it as desired.
Guidelines for QR-Code Usability
1. Tell Users What a QR Code Does and Where It Came From
Unlike links with labels or raw URLs that contain destination information, QR codes have no information scent by themselves. They tell users nothing about where they lead or what will happen when they are scanned. Designers must provide enough contextual information about the code to convince the user to scan it. Without contextual information, QR codes are not trustworthy or enticing.
