How to Create a Coupon QR Code: Promo Codes, Vouchers & In-Store Offers (2026)

1. First, Create the Voucher Code in Your Store or POS

A QR code displays a promo code, but your checkout is what accepts it. Before you make the QR code, create the voucher code where customers will redeem it:

• Online stores: In Shopify, WooCommerce, or similar platforms, create a discount code (for example `SPRING20`). Set the discount value, minimum spend, eligible products, start and end dates, and usage limits there.
• In-store POS: Create the matching discount in your point-of-sale system (Square, Toast, Lightspeed, and others), so cashiers can apply it at the till.
• Choose a clear code name: Short, readable codes such as `WELCOME10` are easy to type if someone can't copy. Avoid look-alike characters such as O and 0.
• One code per campaign: A different code for each flyer, window sign, or mailer lets your sales reports show which channel drove redemptions.
• Set the expiry in the system that enforces it: The coupon page displays an expiry date, but only your checkout or POS can actually block an expired code.

2. What Customers See When They Scan a Coupon QR Code

The Coupon Offer type in TryQRMint creates a hosted mobile coupon page, so there is no need to build a landing page yourself. The page includes:

• Offer title: The headline value, such as 'Get 20% Off Your Next Order'.
• Terms and description: Short conditions, for example 'Valid on all online purchases over $50'.
• Promo code with a Copy code button: One tap copies the code to the phone's clipboard, ready to paste at an online checkout.
• Valid until date: The expiry date you choose is shown clearly, which builds honest urgency.
• Works in-store too: Customers can show the coupon screen to a cashier, who types or scans the code into the POS.

3. How to Create a Coupon QR Code in TryQRMint (Step by Step)

Coupon Offer is a dynamic QR type, so it starts with the 7-day dynamic trial (up to 2 dynamic codes) and then needs a Pro or Business plan to stay active. Here is the flow in the Studio:

• Step 1 — Pick the type: Open the Studio and choose 'Coupon Offer' from the dynamic types.
• Step 2 — Enter the offer: Fill in the Offer Title and the Terms & Description fields.
• Step 3 — Add the code and date: Enter the Promo / Discount Code exactly as it is set up in your store, then pick the Expiration Date.
• Step 4 — Design the QR code: Apply your brand colors, add your logo, and choose a frame with a clear call to action such as 'Scan for 20% Off'.
• Step 5 — Preview, sign in and save: Check the live mobile preview of the coupon page, then sign in and save the code to your dashboard.
• Step 6 — Download and test: Download a PNG (or SVG during the trial and on paid plans), scan it with a phone, tap Copy code, and complete a test checkout with the code.

4. Coupon QR Code vs. Coupon Barcode vs. Printed Promo Code

These three formats solve different problems, and many retailers use more than one:

5. Where to Put QR Code Offers

QR code promotions work best where people have a moment to scan and a reason to come back:

• Shop windows: 'Scan for 10% off today' turns passing foot traffic into store visits, even after hours.
• Receipts and bag inserts: A 'next visit' offer encourages a second purchase.
• Product packaging: A reorder discount inside the box rewards repeat buyers. See our ecommerce packaging QR code guide.
• Direct mail and flyers: Use a separate code per mailing area to compare response.
• Tables and counters: Restaurants and cafes can offer a dessert or loyalty discount.

6. Tracking QR Code Promotions and Redemptions

You have two sources of data, and together they tell you how a promotion performed:

• Scans (TryQRMint): Each dynamic coupon code shows total and unique scans, country and city, device, and scans over time. This tells you which placements get attention.
• Redemptions (your store or POS): Discount reports show how many times each promo code was actually used and the revenue it brought in.
• Scan-to-redemption rate: Divide redemptions by unique scans for each campaign. A high scan count with few redemptions usually means that the offer or terms need work.
• Compare channels: Create one coupon QR code and one promo code per channel, then compare both numbers. For broader campaign tips, read our QR code marketing best practices.

7. Printing Tips and Troubleshooting

Avoid these common problems before you print a large batch:

• Code rejected at checkout: Check that the promo code on the coupon page matches the store exactly, including capitalization, and that the discount is active.
• Code too small: On flyers and receipts, keep the QR code at least about 2 cm (0.8 in) wide, and test the actual print. Our QR code sizing guide covers larger formats.
• Low contrast or busy backgrounds: Use a dark code on a light area of the design.
• Coupon page stops opening: Dynamic codes need an active trial or paid plan. If your plan lapses, the code stops working until you renew.
• Not scanning at all? Work through our QR code not scanning checklist.
