Dynamic QR codes: what they are, how they work and when you need them

If you've been reading about QRs for a while, you'll have heard the term dynamic QR code and seen many providers sell it as the solution to all problems. The reality is more nuanced: there are cases where a dynamic QR is essential and cases where it's an unnecessary expense. In this guide I'll explain the difference, how it works internally, and when it's worth paying for one.

What is a dynamic QR code

A dynamic QR code is a code that does not directly encode a final URL, but a short URL that belongs to a QR provider. When someone scans the QR, they first land on the provider's server, it records the scan, and then redirects the user to the final URL you've configured.

The trick is that you can change the final URL at any time, without touching the physical QR. The code stays the same, but the destination changes.

Dynamic QR vs static QR: key differences

| Feature | Static QR | Dynamic QR | |---|---|---| | Final URL encoded in the QR | Yes, directly | No, goes through a redirector | | Change destination without reprinting | No, must regenerate the QR | Yes, from a dashboard | | Scan analytics | No | Yes (date, time, location, device) | | QR expiration | Does not expire | Depends on the provider | | Cost | Free | From 5 to 50 USD/month depending on plan | | Provider brand in the URL | No | Sometimes, depending on plan | | A/B testing of destination | No | Yes |

How a dynamic QR works internally

  1. You create the QR in the provider's dashboard. You give them a final URL (e.g., https://yourrestaurant.com/summer-menu).
  2. The provider generates a QR that encodes their own short URL, something like https://qrprovider.com/aXyZ123.
  3. You print that QR on the menu, storefront, packaging, wherever.
  4. The customer scans and lands on https://qrprovider.com/aXyZ123.
  5. The provider's server: records the scan (timestamp, approximate IP, user agent), and redirects (HTTP 302) to https://yourrestaurant.com/summer-menu.
  6. You change the final URL from the dashboard whenever you want. For example, in September you change to https://yourrestaurant.com/autumn-menu. The physical QR stays the same.
  7. All scans are counted in your analytics dashboard.

When a dynamic QR code is worth it

1. Frequent destination rotation

If you change the URL more than once a month, a dynamic QR saves you from having to reprint material. This applies to:

  • Restaurant menus with seasonal rotation.
  • Promotions that change every few weeks.
  • Campaign landing pages that get updated.
  • Event posters with changing information.

2. You need to measure impact

A static QR doesn't tell you how many customers scanned it. A dynamic QR gives you:

  • Total number of scans.
  • Scans by date and time.
  • Approximate location (country, region, city).
  • Device type (iPhone, Android, tablet).
  • Whether the scan completed or failed (couldn't redirect).

This is worth gold if you're measuring the ROI of a campaign.

3. A/B testing of destinations

You have two versions of the same landing page and want to know which converts better. With dynamic QR, you create two QRs pointing to different versions and compare results. With static QR, you can't.

4. Managing multiple QRs

If you have tens or hundreds of QRs (restaurant chain, multiple events, products in a catalog), a centralized dashboard is the only way to manage them.

5. Personalizing the destination by context

A practical example: the same QR on a product box, but the destination changes by season. The physical QR is the same, only the URL changes.

When it's NOT worth it

1. The URL never changes

If the destination is stable (a link to your site, a PDF, a page you don't update), a free static QR is enough. Don't pay for something you won't use.

2. You don't need to measure

If the QR is just for the customer to access a resource, and you don't care how many scan it, you don't need dynamic.

3. You have one or very few QRs

The cost of a provider (5-15 USD/month minimum) doesn't pay off if you only have 2-3 QRs. With 10 or more, it starts making sense.

4. The audience is very local and doesn't move

If the QR is always seen by the same people (regular customers of your bar), you already roughly know how many scan it: it's your customer count. You don't need precise data.

Dynamic QR codes: common providers

There are dozens. These are the best known in the English-speaking market:

  • QRCode Monkey (free and paid plan): allows custom design, but the free version is only static QR.
  • Bitly (free with limit): better known as a shortener, also allows generating dynamic QRs with basic analytics.
  • Beaconstac (paid): specific for dynamic QRs, with advanced analytics, integrations with HubSpot, Salesforce, etc.
  • QR Tiger (free with limit, paid plans): custom design, analytics, volume plans.
  • Flowcode (free with limit): very popular in the US, premium design.
  • The QR Code Generator (free with limit, paid plans): one of the oldest.
  • Eventqode (paid, Eventqode app): if in the future we build our own dynamic QR system, it will fit here. For now use the free static generator at /generador-codigo-qr.

Risks of dynamic QR codes

  1. The provider shuts down: if the provider disappears, your QRs stop working because nobody resolves the redirector. This happened with several startups. If your business depends on QRs, consider a provider with several years in the market or set up your own system.
  2. Provider outages: if the provider's server goes down, all your QRs become temporarily inactive. Some major providers have 99.9% SLAs, but not all.
  3. Provider brand in the URL: on free plans, the short URL carries the provider's name (qrprovider.com/x123). This looks unprofessional. Paid plans usually allow custom domain (qr.yourbusiness.com/x123).
  4. Latency: the redirector adds a step. A customer scanning a dynamic QR takes 100-300 ms longer to reach the final URL than with a static QR. Rarely noticeable, but it exists.
  5. Subscription you forget to cancel: if you stop paying, the QRs stop working. Keeping a paid QR implies long-term commitment.

Alternative: build your own dynamic QR system

If you have technical knowledge or a trusted dev, you can set up your own dynamic QR system at minimal cost:

  • Backend: a database (Postgres, MongoDB) with a qr_codes table (id, slug, destination_url, created_at, scan_count).
  • Public endpoint: GET /r/[slug] that records the scan and 302s to destination_url.
  • Admin panel: to create/edit QRs and view analytics. Can be a Notion + scripts, or a small Next.js app.
  • Cost: from 0 USD/month (Vercel free tier + MongoDB Atlas free tier) up to 20 USD/month for high traffic.

If you set it up this way, no provider can shut down and break your QRs.

Dynamic QR codes: executive summary

| Question | Answer | |---|---| | What is a dynamic QR? | A QR that points to a redirector managed by a provider or by you. | | When do I need one? | When you rotate the URL, need to measure, or manage many QRs. | | When DON'T I need one? | Stable URL, no need to measure, few QRs. | | How much does it cost? | 5-50 USD/month, or free if you build your own. | | What's the risk? | Provider can shut down, outages, brand in the URL. | | Alternative? | Build your own system, or use static QR if you don't need the advantages. |

Conclusion

Dynamic QR codes are a powerful tool, but they're not for everyone. If you rotate your menu every season, want to measure how many people scan your poster, or manage a chain with 50 locations, they're essential. If you have a bar with a stable menu and three tables, a free static QR works perfectly.
