QR codes have gone from gimmick to essential business tool in just a few years. The pandemic pushed everyone to scan codes for menus and contactless payments, and now customers expect this convenience when shopping.

64% of shoppers have scanned a product QR code in-store, and 42% say it significantly improved their experience. That's massive adoption.

Here's what makes "scan to checkout" different from regular QR codes: instead of just linking to a homepage or product page, these codes take customers straight into a pre-loaded checkout flow. One scan, and they're ready to buy. No searching, no navigation, no friction.

For physical products, this creates a bridge between the real world and instant commerce. A customer picks up a product, scans the code on the packaging, and completes their purchase before putting the item back on the shelf. You've just captured a sale that might have been lost.

This guide shows exactly how to put QR codes to work that lead to checkout, with proven tactics from brands already doing this successfully in 2025.

What Is a QR Code to Checkout and How Does It Work?

A QR code to checkout is a scannable code that takes customers directly to a ready-to-buy online checkout flow. Not a homepage. Not a product page. A checkout page where the item is already in their cart, discounts are applied, and they just need to confirm payment.

The magic happens in the URL the QR code encodes.

Tools like Checkout Links can generate special URLs that pre-configure an entire purchase flow (specific items, quantities, discounts, even customer data for returning buyers). When someone scans a QR code, that URL loads on their phone and hands them a complete checkout session.

Static vs. Dynamic QR Codes: Which Should You Use?

Static QR codes embed a fixed URL directly. Once printed, you can't change where it points. If you encode a checkout link for Product A, it will always lead to Product A. These work fine for permanent product packaging.

Dynamic QR codes use a redirect service that you can update later. The physical QR image stays the same, but you can change the destination URL or track detailed analytics. This is better for marketing campaigns where offers might change.

Most businesses should use dynamic codes. The flexibility and tracking data are worth it. Checkout Links supports dynamic QR code generation with full customization and analytics integration.

Why Physical Products Need QR Code Checkout

The benefits extend beyond "it's convenient." QR codes that lead to checkout solve real business problems:

→ Bridge Offline and Online Sales Channels

Physical products become interactive storefronts. A QR code on out-of-stock shelf labels lets customers order online for delivery, capturing sales that would otherwise be lost.

64% of shoppers already scan product QR codes while shopping, so this meets them where they already are.

→ Remove Friction from Mobile Shopping

Mobile shoppers are impatient. If a page is slow or requires too many clicks, they abandon the cart. A well-designed "scan to checkout" removes steps.

No searching. No remembering URLs. No typing on a small screen. Just scan and buy.

For repeat purchases, this is especially powerful. Imagine a customer who loves a particular coffee. When they run out, they scan the code on the empty bag, and boom, a new bag is ordered. That's the shortest possible path to repurchase. Checkout Links' customer reorder feature enables this exact flow with one-click simplicity.

→ Capture Impulse Purchases at Peak Interest

When someone picks up a product to examine it, that's peak interest. A QR code lets you capture that moment before they put it down and forget about it. The purchase happens while they're still engaged.

→ Track Which Offline Marketing Actually Drives Sales

Every QR scan can be tracked.

Put a unique code on each marketing channel (packaging, flyers, store displays, trade show materials), and you'll finally know which offline touchpoints actually drive revenue. Add UTM parameters like utm_source=packaging or utm_campaign=QR-Jan2025 to track exactly where sales come from.

→ Cost-Effective Deployment for Any Business

Generating QR codes is essentially free. Printing them on packaging or signage adds minimal cost. Unlike fancy AR experiences or expensive hardware, QR codes work on any smartphone camera. No app required.

Even small businesses can do this affordably.

Checkout Links, for example, generates branded QR codes automatically for any checkout link you create, at $15/month for unlimited links and scans.

The bottom line: QR codes to checkout turn physical products into sales opportunities. Every package, poster, and display becomes a potential point of purchase.

5 High-Impact Ways to Use QR Codes on Physical Products

① Product Packaging: Reorders and Upsells Made Easy

Packaging isn't just branding. It's a portal to the next purchase.

Print a QR code on boxes, labels, or inserts with calls like "Scan to Reorder" or "Buy Again with 10% Off." This works brilliantly for consumables:

• Food products

• Beauty items

• Supplements

• Anything customers need to replenish

A coffee brand could include a QR code on the bag that leads to a checkout for a new bag (perhaps with a subscription discount). When customers run low, they scan and reorder in seconds. Creating reorder links with customer-specific prefill makes this seamless.

You can also upsell with packaging QR codes. "Scan for Accessories" on an electronics box could lead to a pre-loaded cart of recommended add-ons. Capitalize on the unboxing moment when customers are most engaged with the brand.

Research shows that placing "Scan to Reorder" codes on packaging can turn one-time buyers into repeat customers seamlessly. It's like having a salesperson in every box.

② Retail Shelf Tags: Recover Out-of-Stock Sales

The biggest opportunity here is out-of-stock recovery. When an item is sold out on the shelf, put a sign with a QR code: "Scan to Buy Online Now." Customers can order for home delivery instead of walking away empty-handed.

Even for in-stock items, shelf QR codes serve customers who prefer shipping or don't want to carry items. Some shoppers specifically want to browse in person but buy online.

General in-store signage works too. Posters or standing displays with "See something you like? Scan to buy without waiting in line" enable self-checkout via phone. This merges physical browsing with digital buying.

Place QR codes in front of any out-of-stock product with a message like "Scan to order for home delivery." You'll salvage sales and track exactly how physical merchandising drives online revenue with built-in analytics.

③ Print Ads and Catalogs: Make Every Page Shoppable

Physical marketing materials should enable instant shopping. Include QR codes in magazine ads, direct mail catalogs, and event flyers.

If a catalog features a new collection, put a QR code next to each product or on the page that says "Scan to Purchase." Readers don't have to search the site later. They scan, and the item is ready to buy.

For print promotions, the QR link can auto-apply a special discount. Dynamic QR codes are perfect here because you can update the destination later if the promotion changes, preventing dead codes on old prints.

Pro tip: Include a short vanity URL under the QR code in print (like YourStore.com/NEW2025) so readers have confidence about where it leads. This also gives an option for those who can't scan to type it in. Custom link previews let you control exactly what information displays when sharing.

④ Trade Shows and Events: Convert Interest into Instant Sales

At events, you often have limited inventory or just samples. QR codes capture interested visitors and convert them into online customers immediately.

Imagine handing out samples of a new beverage at a trade show. Each sample has a QR code: "Scan to Order Full-Size with Show Discount."

Event attendees can purchase bundles at special expo pricing, with orders shipping the next day. The booth interaction becomes an instant sale.

Pop-up shops benefit similarly. Use QR codes to sell items not physically present or let customers order while traveling light. You can even put codes in windows for after-hours sales when the pop-up is closed but people are window shopping.

Events are perfect for limited-time offers via QR. Schedule links to activate and deactivate automatically, and use passcodes for VIP early access. Track exactly how many orders came from Comic Con versus other events with attribution tracking.

⑤ Product Manuals: Accessories and Replacement Parts

If a product includes a manual or insert, add a QR code for related products or warranty registration.

A kitchen appliance might have a booklet with "Scan to Buy Accessories," linking to a cart of extra attachments. Or a warranty card with "Scan to Activate Warranty (and get a special accessory offer)." This streamlines registration while pitching a cross-sell.

For products with consumable parts (water filters, electric toothbrush heads), include QR codes for replenishment. The insert might say: "Time for a refill? Scan to order replacement parts."

Major brands like Samsung now place QR codes on appliances for easy registration, and the same scan could lead into recommended add-ons with smart cart bundling.

How to Set Up QR Code Checkout (Step-by-Step)

Setting this up is straightforward with modern tools. Here's the complete process:

Step 1: Create Your Checkout Link

First, you need a URL that takes customers to a pre-loaded checkout.

If you're on Shopify, you can manually create cart permalinks or use an app like Checkout Links to generate special URLs. Checkout Links lets you assemble a cart (one or multiple products, specific quantities, discounts, free shipping) and gives you a short URL representing that exact configuration.

Decide the destination type:

→ Direct to checkout: Fastest path to purchase (recommended for single products)

→ Cart page: If you want users to potentially add more items

→ Custom landing page: For products needing more information before purchase

Choose what provides enough info to convert without adding friction. Learn more about optimizing link performance for maximum conversion.

Step 2: Generate the QR Code Image

Once you have your checkout link, turn it into a QR code image. Several options:

Built-in generator: Some platforms create QR codes with one click. Checkout Links has a "Generate QR code" feature where you choose color and style, and it produces the image automatically.

Online QR code generators: Free tools where you paste the URL and download a QR. Use reputable services that support dynamic codes if you want tracking.

Design software plugins: Adobe and Canva have QR code plugins to insert codes directly into artwork.

You'll end up with a QR code image file (usually PNG or SVG).

Step 3: Customize the Design (Optional but Recommended)

Plain black-and-white codes work, but customization improves trust and brand recognition:

Critical: Avoid light colors like yellow or red for the code itself. Scanners have trouble with those. Black or dark blue/purple on white is safest. Always test with multiple devices before finalizing

Checkout Links lets you customize color and style to match brand identity while maintaining scannability.

Step 4: Print and Place Strategically

Now integrate the QR code into its intended location:

For product packaging: Print it directly on boxes or labels. Choose visible spots that don't ruin aesthetics. The back or side panel with a call-to-action (like "Scan to Buy Again") works well. Avoid curved surfaces and seams.

For shelf labels or signage: Print on durable cardstock or stickers. Place at waist to eye level for easy scanning. Generally, QR codes should be at least 1.5 cm (0.6 inches) each side for reliable scanning at typical phone distance.

For flyers and ads: Embed the code in your layout with white space around it. A "quiet zone" border around the code is required for scanning. Don't crowd it with text or images.

For events: Print tabletop signs or posters. Place them where people naturally pause and can pull out phones (booth counters, near displays).

Always include a clear instruction near the code: "Scan to Purchase," "Scan to Order with Free Shipping," or whatever fits. This nudges action and assures users scanning will lead to a desired outcome. Studies show simple "Scan me" text significantly increases engagement.

Step 5: Test Before Mass Production

Before printing 5,000 boxes or rolling out new shelf tags, test thoroughly:

• Multiple devices: Use different phone brands and models (older and newer) to scan the printed version

• Various angles: Test from standing position, about 1-2 feet away

• Lighting conditions: Try it under fluorescent store lights or dim expo lighting

• Mobile experience: Verify the landing page loads quickly and works smoothly on mobile (if it takes more than a few seconds to load, you'll lose users)

• Discount verification: Ensure promotions embedded in the link apply correctly at checkout

• Tracking setup: Scan a few times yourself and verify hits show up in your analytics dashboard

Iron out kinks now, not after 10,000 prints.

Step 6: Launch and Educate Your Customers

Deploy the QR codes: start printing on packaging, place signage in stores, send out flyers. Then let customers know what they are.

A social media post or email can help: "Next time you get our product, look for the new QR code on the box. Scan it to instantly reorder with a special discount!"

Train in-store staff so they can confidently explain it if asked. Given how common QR usage is now, you won't need much convincing, but clear communication maximizes adoption.

Best Practices for High-Converting QR Codes

Small details separate codes that convert from codes that gather dust:

Make QR Codes Big Enough to Scan

Don't shrink QR codes too much. The minimum for retail settings is about 14.6 mm x 14.6 mm. Bigger is better, especially if it might be scanned from a distance or behind glossy packaging.

Maintain a quiet zone (blank margin) around the code. No graphics or text should touch the code on any side. Print at high resolution so modules (squares) are crisp.

High Contrast Is Non-Negotiable

QR modules should be much darker than the background. Black on white is optimal. If your brand uses colored codes, stick to very dark hues on very light backgrounds.

Never invert (light code on dark background) unless thoroughly tested. Avoid red/orange for the dark color because scanners use red light and might fail to read them.

Pretty is good, but scannable is paramount.

Add Clear Call-to-Action Text

Tell people what to do and why. Examples of effective copy:

• "📱 Scan to Buy Now (Get 15% off instantly!)"

• "Scan this code to order on your phone"

• "Scan to Reorder (Running low? We'll ship in 24 hours)"

A QR code with no label is a missed opportunity. Some might ignore it if unsure what it does. Others might be wary (given the rise in QR phishing). Branding and explaining the code increases usage and builds trust.

Match Landing Pages to User Intent

If the code says "Buy now" but opens a homepage, that's a disconnect. Make sure the QR URL goes to a checkout or cart page for the correct product.

As a rule: don't use QR codes to drop people on generic pages. Deep-link to the exact item or offer. For straightforward products, going straight to pre-filled checkout is often the highest-converting path.

Optimize for Mobile Speed

Anyone scanning a QR is on a mobile device. The checkout page must be mobile-friendly and fast.

Test on 3G/4G speeds. Mobile visitors leave if a page takes more than 3 seconds to load. Remove unnecessary scripts. Enable Apple Pay and Google Pay for one-tap payment.

Checkout Links automatically optimizes for mobile and integrates with Shopify's native checkout, so you don't need to worry about performance.

Use Dynamic Codes for Better Tracking

Deploy separate codes for different channels (packaging, store poster, print ad). Use unique links or dynamic codes for each so you can compare performance.

Generate one checkout URL for "Winter Campaign Poster" and another for "Product Box." The slight difference in URL (via UTM tags or unique IDs) gives you insights. 95% of businesses using QR codes do so to collect customer data and track behavior with robust analytics.

Build Trust with Security Measures

A growing concern is "quishing" (QR-code phishing). Scammers sometimes place fake QR stickers over real ones in public places, duping people into visiting malicious sites.

To reassure customers:

→ Use your own domain in the QR link (like yourstore.com). When they scan, their phone previews the URL, and seeing a familiar domain makes them comfortable.

→ Add fine print: "(You'll see our official website URL when you scan)."

→ For critical in-store signage, use tamper-evident stickers or regularly inspect codes to ensure they haven't been covered.

How to Track QR Code Performance and ROI

One major advantage of QR checkout is direct tracking and ROI measurement.

Add UTM Parameters to Every QR Code

Set distinct utm_source or utm_campaign values for each deployment with Checkout Links' UTM tracking. Examples:

• utm_campaign=QR_InStore

• utm_campaign=QR_Packaging

• utm_campaign=QR_SpringFlyer

Sales dashboards will segment revenue by source. Shopify analytics will attribute sales to referring links with UTM tracking.

Track Scans and Conversion Rates

Not everyone who scans will buy. Get data on both scan count and resulting orders with comprehensive analytics.

If 100 people scanned the code on a product box and 20 completed checkout, that's a 20% scan-to-purchase conversion (quite high compared to email or ads). If another code shows only 2% conversion, investigate why.

Key Metrics to Monitor

If you have lots of scans but few purchases, the checkout flow might be too abrupt. Maybe you need a landing page with reviews or product details to build confidence.

Calculate ROI Simply

Printing QR codes is cheap. The main cost might be an app subscription or minor design expenses.

Suppose you spent 50 product, that's $2,500 in revenue directly attributable. Many companies find QR codes drive incremental sales they otherwise wouldn't get (turning passive interest into active purchases).

At just $15/month, the ROI threshold is extremely low.

Gather Customer Feedback

Ask customers if they found the QR code useful. This can be informal (sales associates asking, or a survey in confirmation emails).

Feedback might reveal insights like "I wished it showed reviews before checkout" or "The discount didn't apply." You can iterate and improve continuously.

Celebrate wins internally. When your team sees "the packaging QR code brought 300 extra orders last quarter," that builds support for expanding the program.

Why QR Checkout Is the Future (Not a Fad)

All signs point to QR codes becoming integral to commerce, not a temporary trend:

Retail Is Standardizing on 2D Barcodes

By 2027, retailers globally are moving toward 2D barcodes (like QR codes) at point-of-sale. An initiative called Sunrise 2027 led by GS1 means many products will carry QR or DataMatrix codes scanned at checkout counters instead of old 1D barcodes.

These same codes can embed product URLs (via GS1 Digital Link), meaning every physical product might have a scannable digital link by default. Consumers will be habituated to scanning product packages for information and purchasing.

QR Payments Are Mainstream Globally

In countries like China and India, QR code payments are standard. India's UPI system handled 20+ billion QR-based transactions in a single month (August 2025).

The gap between scanning to add to cart and scanning to pay is closing. We may soon see "scan and pay for this product" flows where QR initiates checkout with mobile wallet payment.

Younger Demographics Expect QR Code Experiences

83% of Gen Z consumers and a majority of Millennials use QR codes frequently, making it crucial for targeting younger demographics. With over 4.8 billion smartphone users worldwide, the potential audience is massive.

The novelty has worn off. QR is now simply a tool (like the web itself) that people use when it offers value.

QR Codes Enable AR and Authentication

QR codes also trigger augmented reality experiences (scan to see 3D product models) and verify product authenticity. A shopper who scans to authenticate a luxury item could in the same flow be offered related products or insurance.

The synergy of informational and commercial scanning will expand.

How Checkout Links Simplifies QR Checkout

Setting up QR checkout flows manually can be tedious. You'd need to:

• Generate custom cart URLs for each product or bundle

• Add discount codes and track their usage

• Create and host QR code images

• Set up analytics tracking

• Manage updates when promotions change

Checkout Links handles all of this automatically for Shopify merchants.

What Checkout Links Does

Checkout Links is a Shopify app that creates smart URLs leading directly to pre-configured checkout flows. Each link can:

• Prefill carts with specific products and quantities

• Apply automatic discounts or free shipping

• Enforce usage limits or passcodes

• Personalize for returning customers (prefill shipping addresses, previous purchases)

• Track revenue attribution in native Shopify analytics

And critically for physical products: generate branded QR codes instantly.

The QR Code Feature

In the Checkout Links dashboard, you can generate a QR code for any checkout link with one click. Choose the color and style to match your brand, and it produces a high-quality image ready for printing.

Want a QR code for "Scan to Reorder" packaging? Create a checkout link with the product, apply a loyalty discount, generate the QR, and download or share it. Done in minutes.

Real-World Use Cases with Checkout Links

Example 1: Abandoned cart recovery

Create a link with cart abandonment dynamic enabled and attach a discount. Add UTM tags like utm_source=email and utm_campaign=abandon_checkout. Drop the link into a Klaviyo recovery flow. Track conversions in Shopify analytics.

Example 2: One-click reorders for VIPs

Enable Customer dynamic links with ?c={customer_id} for high-LTV customers. Prefill their last purchase and shipping address. Use per-customer usage limits so the offer can't be abused.
