QR codes became popular during the pandemic because it supports contactless information transfers. People have realized how convenient they are to use and accept them as a part of their daily lives.
Organizations like yours have probably seen what it can do, especially in your operations and promotions. Now, the question is, how do I scan a QR code from a distance?
Consider the maximum scanning distance if you're planning to create QR codes. You'd want to ensure their scannability so they can deliver what you expect them to provide, from generating leads to raising awareness about the products and services you've enclosed in the code.
Remember that you needn't be close to the object to scan the code. These codes can have at least a radius of 10 inches, which increases depending on the code's size. But the QR code must be at least 0.8 x 0.8 inches so users can read it easily.
Users scan QR codes from a short distance if printed on business cards, menus, print tickets, print newspapers, magazines, or display signs for mobile payments. The same goes for scanning the code on product packaging, receipts, public transit posters, brochures, flyers, and digital platforms.
It helps to be knowledgeable about how to scan a QR code on your phone. You only need to point your smartphone at the code, and you will be connected to its content, whether it is a website, menu, or mobile payment system.
Consider its placement if you want to use a QR code for short-distance scanning. If you plan to put a code in a train, consider where the users will scan it. Users close to it and those on the train seats across the code might want to check it. The code should be large enough for people from a bit farther away to scan it.
The rule of thumb is to increase the size of the QR code the farther the potential scanning distance is. If you put the code on a billboard, the code has to be big enough for long-distance scanning.
This rule should be considered when generating QR codes on large displays, posters, vehicles, and shop windows.
The QR code size for long-distance scanning depends on the angles where the users might be, the height of the material where you will place the code, and the maximum image resolution you can use for the code to be clear enough for scanning.
If the maximum scanning distance is 1.5 to 2.5 feet, the QR code should be 2.4 to 6.3 inches. It is often used in catalogs and magazines.
A scanning distance between 4 to 12 feet requires a QR code of 6.3 to 30 inches. It is often the case in window displays and posters.
If users can scan the code from 12 feet to 25 feet, the QR code should be 19 inches to 61.3 inches big.
It will help if you test print the QR codes in three different sizes to check their scannability. Print it bigger if you want a wider scan radius and ensure users can scan the code.
Please don't waste the potential of your QR code to reach more users and distribute its content to more people by making sure that it is scannable both from a short and long distance. Keep in mind these tips:
Users might find scanning a blurry, low-quality QR code image difficult. It is another reason to print several QR codes in different sizes and image resolutions and download them as PNG, JPG, SVG, or EPS.
Print the QR code away from other designs. It will help the QR code reader recognize the code's pixels from the rest of the display or material.
The last thing you need after printing a code is to get asked, "how do I scan a QR code when my phone cannot detect it from its background?" It is bound to happen if there is no proper color contrast between the color used on the code and its surrounding design.
