QR codes are an integral part of our interaction with information these days, be it restaurant menus or marketing campaigns; the little black-and-white grids are a goldmine of possibilities. Like any tool developed by technology, there are a few unspoken rules and etiquettes behind their effective and respectful use. Following is a list of dos and don’ts that will help you use QR codes effectively and avoid some common pitfalls.

1. Placement Matters

When designing or displaying a QR code, be really conscious of its placement. A code on a billboard that’s hard to reach or safely scan defeats the purpose. Instead, ensure the code is positioned in an accessible location where users can comfortably scan without obstruction.

2. Clarity is Key

The QR code should be clearly printed or displayed and must be in great contrast to the background. A poorly printed code will frustrate users and may discourage engagement. Double-check the size and resolution to make sure it’s scannable across devices.

3. Provide Context

Always inform users what they will be scanning for. A QR code with no context in a message leaves them wondering what they’re going to end up with. Whether it’s a link to your latest offers, a survey, or additional information, a short explanation will help to build user trust.

4. Respect Privacy

If your QR code collects data, then transparency is key. Let the user know exactly what data you are collecting and where it will go. Not only does this build trust, but also adds to ethical considerations of privacy regulation.

5. Test Before You Launch

There is nothing worse than a non-working QR code. Test your QR code in different devices and apps before sending it to the wild, ensuring the best experience for your users.

6. Keep It Relevant

Make sure the content your QR code links to is informative and relevant to them. Never send users to irrelevant or expired pages, since it can cause damage to your credibility.
