The Fundamental Distinction

When generating a QR code, you must decide between two architectural approaches: **Static** and **Dynamic**. Choosing the wrong type before sending thousands of flyers to a commercial print shop can lead to broken links or expensive re-printing.

What is a Static QR Code?

In a **Static QR Code**, the destination data (whether a website URL, Wi-Fi password, or vCard contact) is encoded directly into the black-and-white pixel matrix of the code.

**Permanent & Unbreakable:** Because the data lives entirely inside the pattern, static codes work offline and will **never expire** as long as the destination URL remains active.
**No Middleman Server:** Static codes do not route through any intermediary redirect server.
**Limitations:** Once printed, you cannot change the destination URL. Furthermore, static codes cannot track how many times they have been scanned.

What is a Dynamic QR Code?

In a **Dynamic QR Code**, the code encodes a short redirect link (such as `qrnaly.com/q/your-slug`) that routes visitors to your final destination URL on our secure server.

**Editable Destination:** You can change where the QR code points at any time without reprinting physical materials (e.g., updating a seasonal restaurant menu PDF or rotating a promo page).
**Scan Telemetry & Analytics:** Dynamic codes record the timestamp, device operating system, browser, and approximate city/country for each scan.
**Permanence Guarantee on QRnaly:** Unlike scammy competitors that shut down your dynamic QR codes after 14 days to force subscriptions, QRnaly guarantees dynamic redirect permanence.
