FAQ for QR codes for WooCommerce

Got questions about Product QR Codes for WooCommerce? You’re in the right place. We’ve compiled answers to the most common questions to help you get the most out of your QR codes.

General Questions

What exactly does this plugin do?

The plugin generates unique QR codes for each of your WooCommerce products. When customers scan these codes with their phone camera, they’re taken directly to that product’s page on your website. It’s like giving every physical product a direct link to its online counterpart—perfect for packaging, in-store displays, catalogs, and marketing materials.

Do I need technical knowledge to use this plugin?

Not at all! The plugin is designed to be user-friendly. If you can add products to WooCommerce, you can generate QR codes. The basic setup takes just a few minutes, and you’ll find detailed guides for every feature in our documentation.

Will QR codes work with my existing products?

Yes! The plugin works with all your existing WooCommerce products immediately after activation. There’s no need to update or modify your products—QR codes can be generated for any published product in your store.

Can customers scan QR codes with any phone?

Most modern smartphones (iPhone and Android) can scan QR codes directly through the camera app—no special QR scanner needed. For older phones, free QR scanner apps are widely available.

Setup & Configuration

Why should I set a base domain?

The base domain ensures your QR codes always point to the correct website, even if you’re working on a staging site or local development environment. For example, if you set https://mystore.com as your base domain, all QR codes will link to your live site regardless of where they were generated.

What size should I choose for my QR codes?

It depends on how you’ll use them:

Medium (300px): Website displays, email signatures, small stickers
Large (450px): Product packaging, flyers, standard print materials
Extra Large (600px): Posters, large packaging, window displays
Jumbo (750px): Banners, billboards, trade show displays

Remember: bigger QR codes can be scanned from farther away.

Can I change QR code settings after generating them?

Yes, but with an important note: existing printed QR codes will still work (they’ll always link to the same product), but their appearance won’t change. New QR codes will use your updated settings. If you need QR codes with new settings, you’ll need to regenerate and reprint them.

How do I add my logo to QR codes?

Go to WooCommerce → Settings → QR Codes
Enable “Logo on QR Codes”
Click “Select Logo” and choose from your media library
Your logo will appear on all future QR codes at 25% of the QR code size

Features & Functionality

Can I generate QR codes for product variations?

QR codes link to the main product page where customers can select their preferred variation. This approach ensures the QR code remains valid even if specific variations go out of stock or change price.

Is there a limit to how many QR codes I can generate?

No limits! Generate QR codes for one product or your entire catalog. The bulk generator can handle up to 500 products at once, and you can run multiple bulk operations for larger catalogs.

Do QR codes expire?

Never! Once generated, a QR code will work forever as long as the product exists in your store. Even if you update product details, prices, or images, the QR code continues to work – it’s a permanent link to that product.

Can I track QR code scans?

Absolutely! Enable tracking in the settings and configure UTM parameters. You’ll see QR code traffic in Google Analytics or any analytics platform that recognizes UTM parameters. Track which products get scanned most, where scans happen, and which campaigns drive traffic.

What happens if I delete a product?

If a product is deleted or unpublished, its QR code will lead to a 404 error page on your site. Best practice: redirect deleted product URLs to similar products or categories to maintain a good user experience.

Customization

Can I use different colors for my QR codes?

Yes! Set custom foreground and background colors in the settings. Just ensure high contrast between colors—black on white works best, but dark blue on light yellow or dark green on white also scan reliably.

Will my logo affect QR code scanning?

The plugin automatically places logos at 25% of the QR code size with a white background border, maintaining scannability. We’ve tested extensively to ensure logos don’t interfere with scanning reliability.

Can I create QR codes without the logo for specific products?

Currently, logo settings are global. If you need QR codes without logos, temporarily disable the logo in settings, generate those QR codes, then re-enable it.

Technical Questions

Is the plugin compatible with page builders?

Yes! Use our shortcode [product_qr_code] in any page builder:

Elementor: Add via Shortcode widget
Gutenberg: Use the Shortcode block
Divi: Insert in Code module
WPBakery: Add through Text Block

Does it work with WPML or multilingual sites?

QR codes link to product URLs, which WPML and other multilingual plugins handle automatically. Visitors will see the product in their selected language.

Will QR codes slow down my website?

No impact on frontend performance! QR codes are generated on-demand and cached. The shortcode loads images efficiently, and bulk operations run via AJAX without affecting your site visitors.

Can I use QR codes in my email campaigns?

Yes, but with a caveat: email clients don’t support direct shortcode rendering. Generate QR codes, save them as images, then insert the images into your emails. Many email platforms support custom image fields for this purpose.

Is the plugin multisite compatible?

Yes! The plugin works on WordPress multisite installations. Each site in the network maintains its own QR code settings and generated codes.

Troubleshooting Basics

QR codes aren’t scanning properly

Check contrast: Ensure high contrast between QR pattern and background
Test size: QR codes smaller than 1 inch (2.5cm) may be hard to scan
Verify print quality: Low-resolution printing can damage QR patterns
Clean surface: Reflective or dirty surfaces interfere with scanning

QR codes lead to the wrong page

Clear your cache (both WordPress and browser)
Check the base domain setting
Verify the product is published
Test in an incognito/private browser window

Logo isn’t appearing on QR codes

Confirm logo is enabled in settings
Check that a logo is selected
Clear browser cache and refresh
Verify the logo file still exists in media library

Bulk download isn’t working

Check PHP memory limit (recommend 256M+)
Try smaller batches (50-100 products)
Ensure sufficient disk space
Check browser download settings

Advanced Questions

Is it possible to bulk update QR code settings?

Settings apply to new QR codes only. To update existing codes with new settings, regenerate them using the bulk generator with your updated preferences.

Security & Privacy

Do QR codes collect personal data?

QR codes themselves don’t collect data—they’re just visual links. However, if you enable tracking parameters, standard web analytics apply when users visit your site via QR codes.

Can QR codes be hacked or changed?

Once generated, a QR code’s destination cannot be changed—it’s encoded in the pattern itself. This makes QR codes secure from tampering. Always generate QR codes from your secure WordPress admin.

QR codes are GDPR compliant as they’re simply links. Standard website privacy policies and cookie consents apply when visitors arrive at your site via QR code.
