8 Uses of QR Codes for Businesses That Generate Real Results
Not all QR codes are equal: these 8 cases have demonstrable ROI
QR codes have moved beyond a passing trend. In 2024, 89% of consumers in Spain used their phone camera to scan a QR at least once a month, according to Statista data. For businesses, the dynamic QR — editable and with analytics — has become a measurable, low-cost marketing tool.
How do hospitality businesses use dynamic QR codes?
Digital menu without reprinting, guest WiFi and post-visit satisfaction surveys. Three uses that cut operational costs and increase Google reviews.
The hospitality sector mass-adopted QR during the pandemic and hasn't looked back. The three most profitable uses:
Updatable digital menu. A restaurant with 16 menus that updates prices 4 times a year saves between €320 and €960 in reprinting. With a dynamic QR, the price change is instant and costs nothing.
Guest WiFi without dictating the password. A WiFi QR encodes the SSID and password. The customer scans and connects automatically, without asking staff. It reduces service interruptions and improves the perceived tech sophistication of the venue.
Satisfaction survey on the receipt. A QR at the bottom of the receipt or on the table takes the customer to a 2-question Google Form. Response rate with QR exceeds 15%, compared to 1–3% for delayed email surveys.
How do retail and packaging businesses use QR codes?
QR on labels linking to product pages, verified reviews and usage instructions. With a dynamic QR, content updates without reprinting the label.
Smart packaging with QR is growing in retail for one simple reason: space on a box is limited, but the buyer's phone screen is not.
Extended product page. EAN-13 on the box for the point-of-sale terminal, QR for the buyer who wants to know more: complete ingredients, usage instructions via video, FAQs, warranty information.
Verified reviews. A QR that takes directly to the Google My Business profile or Amazon product page to leave a review. Works best in the post-purchase moment, when the product is already in the customer's hands.
Instant warranty registration. Instead of a paper warranty form no one fills in, a QR takes to a digital form. It takes 30 seconds on the phone when opening the product.
With a dynamic QR, if you change your product page URL or move to a new review platform, you update the destination without reprinting a single piece of packaging.
What are QR codes used for in print marketing campaigns?
A QR on a flyer or poster converts the physical medium into a measurable channel. With dynamic QR, you can change the destination by campaign phase and measure real reach.
Print marketing had a historic problem: it couldn't be measured. A 5,000-copy flyer didn't tell you how many people read it. The dynamic QR solves this.
Product launch campaign. The poster carries the QR, the QR takes to the launch landing page. When the campaign ends, the destination changes to the permanent product page without reprinting posters that remain in venues.
A/B testing on physical materials. Two versions of the flyer with the same dynamic QR. You change the destination on alternate weeks and measure conversions. No need for two different codes.
Impact tracking by medium. One QR per medium type (flyer, poster, business card) with different destinations. The analytics tell you which medium generates the most real traffic.
In all these cases the dynamic QR includes scan metrics you can export as CSV and cross-reference with your sales data.
How do logistics and manufacturing companies use QR codes?
EAN-13 for retail product identification. Code 128 for internal inventory. GS1-128 for batch and expiry traceability in pharma and food.
In logistics and manufacturing, QR codes coexist with 1D barcodes. Each format has its use case:
EAN-13 — The universal European retail code. Identifies the product at the point of sale of any chain. Generated free at codigo-qr.es, though the company prefix must be registered with GS1 for organised retail sales.
Code 128 — For internal use: warehouse inventory, asset identification, serial numbers. No GS1 registration required, free to use, and the most versatile (full alphanumeric, up to 80 characters).
GS1-128 — For advanced traceability: batch + expiry + GTIN in a single code. Mandatory in pharma and food for distribution chains that require GS1 Application Identifiers.
QR on work orders. Each part or batch carries a QR linking to the production sheet, quality history and assembly instructions. The operator scans with a phone or industrial reader and accesses the information in real time.

Preguntas frecuentes
- How many dynamic QRs does a business need to get started?
- It depends on the use case. For hospitality: one per area or service type (menu, WiFi, survey). For marketing: one per campaign or medium. The Pro plan includes unlimited dynamic QRs at €5.99/month.
- Can QR codes be generated in bulk to label products or assets?
- Yes. The batch generator at codigo-qr.es (Pro plan) accepts a list of up to 200 URLs or values and generates all QR codes at once, downloadable as a ZIP of PNGs or a printable A4 PDF.
- Does the QR track customer location?
- No. Dynamic QR analytics is about scans, not location. It records country, city (by approximate IP geolocation), device and time, but not GPS coordinates or personal identifiers.
- How do I integrate QR analytics with my CRM or marketing tool?
- The most direct way is the CSV export of scans (Pro plan), which you can import into any tool. For more advanced integration, the QR's UTM mode adds parameters to the destination URL that your Google Analytics or CRM is already measuring.
