The Value of the Quick Response code on Badges

The term QR code stands for Quick Response code, which is fitting given that it's designed for quick readability. There's also a number of other good reasons why the veritable QR code should be used when it applies to badges and cards. Good things stand the test of time and this article is reminder of the reasons why the QR code has been in use since 1994.

The QR code is a 2D barcode meaning that it stores information both vertically and horizontally unlike a 1D barcode that stores data only horizontally. The QR code was originally created for the automobile industry to track parts and manufacturing in Japan. Today it’s become ubiquitous with pulling out your smartphone and scanning the QR code in front of you. It could be to look at a menu, check yourself in somewhere, grab some information online, or make an electronic payment. The familiarity and ease-of-use along with ability to store large amounts of information is ideal for placement on credentials, whether like an event badge.  


The QR code while quick like its namesake is also a versatile and robust technology. It can store up to 100 times more data than a traditional one-dimensional barcode. There's also error correction of up to 30%, meaning the code can be damaged up to a certain point and still scans. There's a multitude of ways to create and deploy QR Codes easily and cheaply. Scanova is an online platform that provides a multitude of great ways to generate QR codes along with being a great resource of information.

Since most smartphones can easily scan QR codes with their cameras including the iPhone that does it natively, QR code adoption outside of more traditional applications has accelerated.  Digital Trends explains how easy it is to do this on Android and the iPhone. This is why adding a QR code to a badge or card is so practical. Anyone can easily scan it with their smartphone camera.

We make it an easy on the CredsNow platform to add the QR code merge field that can accept alphanumeric, urls and other common string patterns. The CredsNow QR field is dynamic so you can drop it into your badge or card design so it behaves like a merge field. If you add 100 records then each badge or card generated will contain the distinct merged value. The CredsNow platform is designed to accommodate the use of the QR code and provides the necessary flexibility for the various potential end use applications.

Some other considerations when it comes to the benefits of implementing QR codes on credentials include cost, size, and reliability. The QR code is very inexpensive relative to the benefits of use since it can be printed on almost any surface material. The visual structure contains 3 small distinct squares conceived to ensure scanners will recognize the QR code instantaneously which works well when incorporating into the overall badge design. The size can often be less than a square inch dependent on the amount of data encoded on the QR code. If you're designing a credential, a small square QR code is easier to integrate into the design compared to a long one-dimensional barcode, and it can hold more data.


QR codes have become indispensable in events, particularly on event badges. They facilitate swift check-ins, reducing long queues and improving the overall attendee experience. By simply scanning a QR code on a badge, event management or exhibitors can quickly access attendee information, verify badge validity, and even control access to specific areas within the venue or sessions.  Moreover, QR codes on badges can be linked to personalized schedules, networking opportunities, social media, contact details and digital content, enriching the attendee experience and improving engagement. Adding branding to QR codes has become more common, enhancing brand identity and making it clear what and where to scan.

QR codes have revolutionized the way we manage information on event badges and cards. Their ease of use, security benefits, and compatibility with smartphones make them an ideal solution in our increasingly digital world. As event technology continues to evolve, QR codes will undoubtedly remain at the forefront of innovative solutions, shaping the future of digital interaction, security and information sharing at events.
