No, QR codes themselves do not expire, but their functionality can vary based on whether they are static or dynamic.
While the fundamental code remains scannable indefinitely, the content they link to, especially for dynamic QR codes, can be managed or even deactivated. Understanding the distinction between static and dynamic QR codes is key to knowing their longevity.
Static QR Codes: The Permanent Solution
Static QR codes are directly encoded with the final destination data. This means the information—be it a URL, text, or contact details—is embedded directly into the pattern of the QR code itself.
- No Functional Expiry: Once generated, static QR codes offer a permanent solution. They will continue to direct users to the exact same content without any possibility of modification or deactivation.
- Ideal for Long-Term Use: Because of their permanence, static QR codes are perfect for information that rarely changes.
Common Uses for Static QR Codes:
- Website Links: For linking to a company's main homepage.
- Wi-Fi Access: For easy connection to a public or private Wi-Fi network.
- Contact Information: On business cards, providing permanent contact details.
- Basic Text Display: For displaying simple messages or product serial numbers.
Dynamic QR Codes: Flexible but Managed
Dynamic QR codes function differently. When scanned, they first direct the user to a short URL managed by a QR code service provider. This short URL then redirects to the actual destination content. This intermediary step allows for remarkable flexibility.
- Editable Content: The destination URL or content linked to a dynamic QR code can be changed at any time, even after the QR code has been printed and distributed.
- Trackable Analytics: Service providers often offer analytics on scan numbers, locations, and device types, which is invaluable for marketing campaigns.
- Managed Functionality: While the QR code itself doesn't expire, its functionality can be paused or limited. This pausing can occur based on:
- Campaign Settings: If a specific marketing campaign has an end date, the QR code's link might be deactivated afterward.
- Scan Limits: Some plans or campaigns might have a set number of scans, after which the code's functionality is paused.
- Subscription Status: If the service provider's subscription used to generate and manage the dynamic QR code expires or is cancelled, the redirection might stop working.
When to Use Dynamic QR Codes:
- Marketing Campaigns: For promotions, discounts, or event registrations that are time-sensitive.
- Product Information: Linking to product manuals or update pages that may change.
- Feedback Forms: For collecting customer opinions that might be updated periodically.
- App Downloads: Directing users to app stores, where links might need to be adjusted.
Static vs. Dynamic QR Codes: A Comparison
| Feature | Static QR Code | Dynamic QR Code |
|---|---|---|
| Expiry | No functional expiry | QR code doesn't expire, but functionality can be paused |
| Content | Fixed, cannot be changed after creation | Editable anytime |
| Tracking | No scan analytics | Full scan analytics available |
| Redirection | Direct link | Redirects via a short URL |
| Use Case | Permanent information | Flexible, trackable campaigns, changeable content |
In essence, a QR code's longevity primarily depends on its type and, in the case of dynamic codes, on the management and subscription status with the service provider. For truly permanent solutions, static QR codes are the go-to, while dynamic codes offer unparalleled flexibility for evolving content.
