Getting Started with StackQR

Imagine a bustling café where a customer effortlessly scans a QR code and pays their bill in seconds, bridging the physical and digital worlds seamlessly. In this guide, we explain what QR codes are and show you how to create them easily with StackQR’s natural language interface.

Understanding QR Codes

QR codes, or Quick Response codes, were invented in 1994 by Denso Wave, a Toyota subsidiary, to help track cars during manufacturing. Unlike regular barcodes, which store data in one direction, QR codes can store data in both directions and hold up to 3,000 alphanumeric characters.

When you scan a QR code with your phone’s camera, it reads the black-and-white pattern and displays the information inside. This might be a website, contact details, WiFi info, or any text you want to share. Using QR codes is easy: just point, scan, and access.

Why QR Codes Matter Today

QR codes have become increasingly popular in recent years, transcending various industries. Consider a bustling café where the owner, Sarah, decided to implement QR code payments after noticing customers’ growing preference for contactless transactions. Within a few months, Sarah observed a 30% increase in tipping, as patrons found the process seamless and convenient. In retail, small businesses are using QR codes for promotional activities, such as offering instant discounts or directing customers to special online offers. Restaurants are integrating QR codes into their menus, allowing patrons to view digital menus, order, and even pay directly through their smartphones. Healthcare providers are using QR codes for smooth, efficient patient check-ins and vaccine record management. Meanwhile, event organizers use these codes to streamline ticketing and registration. Service-oriented businesses, such as salons or clinics, use QR codes to streamline appointment bookings, making it easier for customers to schedule visits. The diverse applications of QR codes continue to enhance user experiences across sectors.

Static vs. Dynamic QR Codes: What’s the Difference?

Before you start making QR codes, it’s helpful to know there are two main types: static and dynamic.

Static QR Codes

Static QR codes store information directly in the code. Once created, they cannot be altered, ensuring a level of security and consistency that is ideal for security-conscious users. For example, if you make a static QR code for https://example.com, it will always link to that address. To update it, you would need to generate a new QR code. This fixed nature can empower users who value data integrity and certainty from the outset.

Advantages of static QR codes:

  • Complete privacy—no third-party servers involved

  • Work offline and indefinitely

  • No ongoing costs or subscriptions

  • Faster scanning (no redirect required)

  • Full ownership of your data

Considerations for Static Codes: Great for One-Time Info

  • Content cannot be updated after creation

  • No built-in analytics or tracking

  • Need to regenerate if information changes

Dynamic QR Codes

Dynamic QR codes work differently. They point to a link that can redirect to your final destination. You can change this redirect at any time in the dashboard, so you don’t have to reprint the QR code if you want it to go somewhere else. Imagine you’re running a store, and it’s Monday morning—you need to quickly swap a promotional link for the day’s sale. With dynamic QR codes, you can do this instantly without having to generate new codes.

Advantages of dynamic QR codes:

  • Editable destinations after printing

  • Built-in scan analytics

  • Useful for campaigns that may need updates

Considerations:

  • Require ongoing server infrastructure

  • Depend on a third-party service

  • May have subscription costs

  • If the service goes offline, QR codes stop working

Why StackQR Uses Static QR Codes

At StackQR, we focus on static QR codes because we care about privacy, simplicity, and reliability.

When you create a QR code with StackQR, everything happens right in your browser. This means that the data processing is local and secure; no information is sent over the internet or shared with any external servers. Because your data never leaves your device, you have complete privacy. We never see, store, or access your QR code content, providing peace of mind for businesses handling sensitive information, such as WiFi passwords or internal links. Local generation ensures that privacy-conscious users can fully trust our platform.

Static QR codes last forever. Your QR code will continue to work even if our service changes. You don’t need a subscription or an account, and your printed codes will still work even if a redirect service goes offline.

We understand that dynamic QR codes can be useful too. If you need features like analytics or the ability to change destinations after printing, let us know. We’re considering adding dynamic QR code support in the future, and your feedback will help us decide. Please email features@stackqr.com with your ideas.

Step 2: Describe What You Want

This is what sets StackQR apart from other QR generators. Instead of using dropdown menus or forms, you simply describe what you want in plain English. No tech jargon, just everyday words. The system understands your request and creates the right QR code, making it accessible for everyone, regardless of their technical background.

Example prompts:

  • “Create a QR code for https://mywebsite.com”

  • “Make a QR code for email contact@mybusiness.com subject Inquiry”

  • “QR code for phone +1-555-123-4567”

  • “Create an SMS QR for +1-555-987-6543 message Thanks for visiting!”

You don’t need to remember any special commands. Just type naturally, and StackQR takes care of the rest. If you mention “wifi” with a network name and password, it creates a WiFi QR code. If you add an email address, it makes an email QR code. The system is designed to be easy to use.

Step 3: Generate Your QR Code

Click the “Generate” button or press Cmd/Ctrl + Enter as a shortcut. Your QR code will show up on the screen, ready to use. Try typing something playful now to see how easy and versatile the process is. Whether it’s a website link, WiFi details, or a personal message, turning your curiosity into hands-on learning is just a click away.

If you need to make several QR codes at once, StackQR supports batch generation. Just combine your requests into a single prompt. This is helpful for creating QR codes for a whole team’s contact info or multiple WiFi networks.

Step 4: Download Your QR Code

Click the download button on your QR code. A menu will appear with five format options (Print? Choose SVG; Web? Pick PNG):

  • PNG: Best for web use and most applications. Offers excellent compatibility across all devices and platforms.

  • JPEG: Smaller file size, ideal for email attachments or when file size matters.

  • WebP: Modern format with superior compression. Great for web projects targeting modern browsers.

  • SVG: Vector format that scales to any size without losing quality. Perfect for print materials, from business cards to billboards.

  • GIF: Universal compatibility for legacy systems and simple applications.

Each format includes information about the QR code’s content as embedded metadata. This helps you organize and find your QR codes later.

Step 5: Edit If Needed

Did you make a typo or need to change something? StackQR lets you edit QR codes without starting over. Click the pencil icon on any QR code, make your changes in the form, and your QR code updates right away. There’s no need to regenerate from scratch, offering a safety net that encourages you to experiment and explore creatively. The editing interface is simple to use.

Supported QR Code Types

StackQR supports six primary QR code types, covering the most common use cases:

URL QR Codes

Send people to any website. These QR codes are great for business cards, flyers, and marketing. If you forget to add https://, the system will add it for you.

Email QR Codes

Create QR codes that open a new email with the recipient, subject, and even message already filled in. These are useful for customer support or collecting feedback.

Phone QR Codes

Create QR codes that call a phone number when scanned. These are helpful for contact cards and support materials, and they work with international numbers and country codes.

WiFi QR Codes

Share WiFi access without having to say the password out loud. Just include the network name, password, and encryption type. When someone scans the code, their device connects automatically.

SMS QR Codes

Create QR codes that open a text message with the number and message already filled in. These are great for opt-in marketing or quick ways for people to contact you.

Plain Text QR Codes

You can put any text message up to 1,000 characters in a QR code. Use this for instructions, hidden notes, or anything else that doesn’t fit the other categories.

Best Practices for QR Code Usage

Guarantee a first-try scan by ensuring your printed QR code is at least 2cm by 2cm. Larger codes are easier to scan from a distance.

Ensure effortless scanning with clear contrast. StackQR’s black-on-white codes work best. If your QR code sits on a colored background, verify there’s ample contrast.

Prevent scanning issues by testing your QR code across different devices before printing. Cameras and scan apps may function differently.

Add value with context. Place a short call to action near your QR code to guide users effectively. Try engaging prompts like “Scan & Reserve Your Table Now,” “Scan & Join Our Community Today,” or “Instant Access: Scan to View Details.” Use punchy phrases that clearly communicate the benefits, helping users understand the value of scanning your QR code.

Optimize visibility by placing QR codes at eye level in well-lit spaces. Avoid glare or shadowy areas that might complicate scanning.

Keyboard Shortcuts for Power Users

StackQR provides keyboard shortcuts to help you work more efficiently:

  • Cmd/Ctrl + K: Focus the input field
  • Cmd/Ctrl + Enter: Generate QR code
  • Cmd/Ctrl + D: Download current QR code

Your Privacy Matters

Your privacy is paramount at StackQR. We designed the platform with privacy as a core principle. Think of it as creating QR codes in the privacy of your own living room, where your data remains protected within the walls of your browser. All QR code generation occurs locally using JavaScript, ensuring that your information stays strictly on your device. We never store your QR codes, track your creations, or require any personal information to use the service. This approach allows you to confidently generate QR codes with sensitive information, such as WiFi passwords or internal business URLs, knowing your data never leaves the security of your own space. To enhance data protection, consider sharing QR codes containing sensitive information, such as WiFi passwords, in a controlled manner. Limit the distribution to trusted individuals, and avoid posting them in public spaces to prevent unauthorized access. By practicing safe sharing, you help protect your business data from potential breaches.
