How to Boost Trust in Your Marketing Materials with QR Codes

  • Author: Danny
  • December 2, 2025
11 min read

Whether printed or digital, QR code marketing goes far for a variety of campaigns across countless industries. Both audiences and marketers reap the tangible benefits of QR code marketing for meaningful content sharing and QR code tracking with valuable analytics to manage campaigns. Marketing with QR codes now brings one-dimensional content to life, creating an interactive experience between the creator and the user. Now that most printed materials are out and sustainable, digitally stored materials and cell phones are in, save the wasted paper and ink and add true, digital value to your campaigns while providing necessary and fun content for your audience. We’ll show you how the value of boosting trust through producing marketing materials with QR codes will make your campaigns more effective with every scan.

Increase brand awareness with QR code marketing on materials

Brand awareness is important for well-known and emerging companies alike. When new companies, independent workers, and artists want to get their name out there, building a client base is always a battle. For well-known companies, maintaining consumer loyalty, keeping up with competitors, and protecting themselves from impostors is also a battle. When you increase brand awareness and have an effective channel to do it with, such as with social media, people trust your brand or who you are as an individual. QR code marketing on physical materials like street billboards, QR codes on business cards, gallery and concert posters, networking banners, and more, connect you with your audience, help build your reputation and give you a competitive edge amongst your colleagues. Trust is also built when you provide truly great content and share it with the world. This is what distinguishes your brand from your competitors.

Pro tip💡Make a branded QR code with a logo to increase brand awareness on your campaigns, so when people see your marketing materials, they recognize you, either as a company or for your own personal style.

Do A/B testing through QR code marketing

A/B testing with QR codes is a great way to measure which version of a marketing asset (flyer, poster, packaging, etc.) drives better engagement. This builds consumer trust because once you see what works better for your audience, you can fine-tune your marketing strategy to suit their needs. QR code analytics enable the QR code creator to see when, where, and on what devices the QR code was scanned. This information is gold for marketers and audiences because the benefits work both ways. 

Another way to boost trust with QR code marketing on materials is to A/B test what materials actually worked by how many scans you’re receiving. If one flyer, poster, print, or their messages entice your audience to scan more than another, it could be based on the marketing design, if it’s properly branded, or if your message states that the content added to the code is worth scanning. Is it a discount code or a coupon? Is it an event schedule? Is it a portfolio page or social media code? Depending on your needs and what the audience wants, QR code marketing goes way further due to its analytics than marketing in the past with campaigns that were difficult or not possible to measure. 

Keep QR code types in mind when marketing with QR codes

QR code marketing on your materials should reflect your brands’ image, the campaign theme, and can be adjusted for seasonal campaigns, events, and more. There should also be a call to action on every code to get people scanning. But a customizable QR code is only the beginning. It’s what’s inside that counts the most!

Take a look at our different types of QR codes, and we’ll give you some examples about how to use each one:

Website QR Code: Give your audience an enticing message written on your marketing materials about where they can check out your website that connects to your portfolio, your ecommerce store, your social media, ticket sales, event calendars, and more! 

PDF QR Code: Do you have a cool white paper that you want to distribute? Or maybe you’ve produced an ebook that is in a PDF file too big to email! By reducing the size of the file, you can still maintain the quality. Download your PDF to the PDF QR code generator and see how quickly the code scans and the information is automatically stored in your phone.

Multi-Link QR Code: The multi-link QR code is perfect for linking multiple websites, social media sites, PDFs, etc., to the same code. They are so valuable because the code routes the scanner to one place where your audience can connect with you anywhere. You can share premium content in this space or create a two-way conversation with audiences through a variety of media channels they decide to connect with you on. This is the ultimate boost in consumer trust. When you use this type of QR code marketing on your materials, people are intrigued to scan and find out more!

vCard QR Code: QR codes on business cards, posters, flyers, banners, and more, that display your contact information, are one of the most popular codes someone can create. The vCard QR code enables its creators to list all of their contact information, including their business, emails, phone numbers, and social media sites. All of these are automatically input in the scanners’ mobile phone, eliminating human error as long as you put in the correct information. You can also add websites that lead to your portfolio or your company’s website, if it’s a business contact QR code. The vCard is a dynamic QR code as are all of Trueqrcode’s types. Therefore, when your information changes, the code doesn’t have to. Just edit your information and that’s it. 

WiFi QR Code: Now you can enable customers in your coffee shop, business lobby, salon waiting room, and more, to connect to your WiFi without having to give out passwords and manage typos. You can enter your network name, password, choose if it’s hidden, and if it’s encrypted. If that information changes, you can just edit the code in your account without having to reprint it. This is convenient for shops that change passwords frequently to avoid misuse of their WiFi accounts.

Barcode QR Code: Trueqrcode’s GS1 compliant code allows businesses with an inventory to make a barcode QR code for each of their products. These can pull up any information needed to know about the product, such as ingredients, allergens, where it was made, company information, and anything else different industries would need to know about their products. If the information changes, they can be edited on the backend without having to reprint the code when the product is sold. 

Always go for dynamic QR codes

Why should QR code marketing be done with dynamic QR codes? We’ll show you a few of the benefits of using dynamic vs. static QR codes for your campaigns. Having the most updated information directed from your QR codes always maintains trust between the brand and the audience because they know they’re getting the latest information. There is confidence in reliability. 

Firstly, they are editable. Any information you put into a dynamic QR code can be modified later on. This keeps marketing campaigns current and refreshes any outdated information. It also leaves room to make corrections if any errors occurred, although we stress test scanning the code before launching it. You don’t need to reprint a dynamic QR code; you can just edit it on the backend, and it will take care of the rest.

What if your campaign was nearing a product launch? With QR code marketing, it’s easy to begin the campaign by routing the scanner to information about the upcoming product, such as with a URL to a video, a tutorial, a website, or social media reels, to get the audience excited. Then as the launch grows near, you can change the URL to a pre-order page.

Secondly, you can modify the design if you care to reprint it or use it for digital campaigns. Marketing with QR codes enables the creator to customize stunning designs for different reasons like events, seasonal promotions, content, and more. As brands evolve, they can change their look while keeping great content or adding more.

Getting ready for the holidays? Just swap out your branded colors with those of the next holiday and leave your QR code logo in the center. You can edit the holiday campaign from the backend with a discount code, an event page to purchase tickets, or a product page with seasonal promotions. 

The next reason is that dynamic QR codes are trackable. QR code marketing is best done with trackable codes because unknown campaigns can’t benefit marketers the same way as measurable ones. This enables QR code creators to adjust the way they print their codes. A few examples are: printing in certain places, at events, times of the month or year, and anything else they notice that can increase or decrease the number of scans. Not only is this information necessary for marketers, but it also helps them know what their audience wants and needs. 

Let’s say you ran a campaign on two different billboards in two cities. Were the people in one city more inclined to scan than in the other? Or maybe it was that the billboard wasn’t in a walkable location, so it didn’t get as many scans, and it had less to do with the city. Or perhaps your target audience was of a certain age group, and they don’t hang out in that area. Information seen on the Trueqrcode analytics dashboard is telling and it helps marketers complete fruitful campaigns with solid numbers instead of mystery campaigns that don’t achieve their goals. 

Placement matters with QR code marketing

That brings us to our next point! When building trust with your audience, QR code placement is a big factor because not only do people need to trust that it isn’t a mystery or counterfeit code in order to scan, but people scan codes that are placed in convenient locations. Here are a few strong suggestions regarding QR code placement and what you should and should not do.

Dos ✅

  • Print QR codes on billboards that can be scanned in walkable locations.
  • Make QR codes that are the appropriate size according to the marketing materials and make scanning convenient.
  • Put them in places where people trust you're the owner of the code, like at your gallery event, concert if you're a musician, or a banner at a networking convention.
  • QR codes should be placed nicely on the marketing materials.
  • Use contrasting colors and find a way to incorporate your branding into them.
  • Place QR codes on product packaging and appliances.
  • Put QR codes on business cards and merchandise.
  • Leave 1/4" space around the QR code or it can't scan.
  • Consider your audience when you think about where you'll print the code, like in a shopping district with diverse crowds if that's your target.
  • Give them a reason to scan your QR code in the marketing materials.

Don'ts ❌

  • Print QR codes on freeway billboards, which are a car accident waiting to happen.
  • Make QR codes that are so small, crowds must hover around them; or so big that you need to pace backwards, maybe in a busy street to scan them.
  • Put them on flagpoles or street light poles, crooked, so people have no idea where they came from.
  • Use QR codes that are crooked, inconvenient to scan, and unprofessional.
  • Use basic, neutral colors on top of each other and watch the frustration in people's eyes as they scan.
  • Place QR codes in places that are scratched easily so the code is damaged, especially on the corners and becomes unreadable, like the outside of a shipping box.
  • Put QR codes on TV screen adverts that change rapidly.
  • Leave no space around the QR code and get no scans.
  • Place codes in locations where your target audience isn’t present, like a retirement home if you're targeting young adults.
  • Leave the code without promises and decrease your number of scans.

Our final thoughts on building trust through QR code marketing

Audiences are more likely to engage when you have given them a reason to trust your brand and that the QR code they are scanning is safe and delivers fantastic content. Marketing with QR codes enables brands and individual creators to go beyond one-dimensional marketing materials, building trust by adding depth to conventional campaigns. Not convinced? Give us a try, and you’ll see how Trueqrcode’s QR code generator improves the value of your campaigns in the long and short term.
