Frequently Asked Questions
Answers about dynamic QR codes, scan tracking, privacy, bulk creation, and print setup.
Last updated: April 20, 2026
Do QR codes expire?
Static QR codes never expire — the destination is permanently encoded in the image and works indefinitely. Dynamic QR codes remain active as long as your subscription is active. QR Master keeps static QR codes functional forever, including on the free plan.
Will QR codes become obsolete?
QR codes are unlikely to become obsolete in the near future. Adoption has accelerated since 2020 — Statista reports that QR code usage grew by over 750% between 2018 and 2023. Every major smartphone camera app now natively reads QR codes without a separate app, removing the main adoption barrier.
Will QR codes replace barcodes?
QR codes will not fully replace barcodes. Barcodes remain dominant in high-speed retail checkout due to laser scanner compatibility and established infrastructure. QR codes excel for consumer-facing use cases: menus, marketing, payments, and product pages. Both formats coexist across different industries.
Do QR codes work through laminate?
Yes. QR codes work through standard laminate because the scanner reads the contrast pattern, not the physical surface. Matte laminate is preferable to gloss, which can cause glare under direct lighting. Avoid laminate with metallic or tinted finishes that alter contrast.
Do QR codes work with a cracked phone screen?
Usually yes, as long as the camera can still capture the QR code image. Minor cracks often do not prevent scanning. A heavily cracked screen that distorts the camera view may cause scanning failures. The QR code itself is not affected — only the device reading it matters.
When were QR codes invented?
QR codes were invented in 1994 by Masahiro Hara at Denso Wave, a Toyota subsidiary in Japan. They were originally designed to track automotive parts during manufacturing. QR stands for "Quick Response." The format was made publicly available royalty-free, which enabled widespread global adoption.
Can QR codes run out?
No — QR codes cannot run out. The QR code standard supports approximately 10^9 unique combinations for a typical URL, far more than could ever be used. Generating a new QR code does not "use up" anything from a shared pool. Each code is generated independently.
What is a dynamic QR code?
A dynamic QR code points to a redirect URL, so you can change the final destination later without replacing the printed QR image.
Why teams use it:
Why teams use it:
- Update the destination after print
- Review scan analytics later
- Keep one printed QR in use across changing campaigns or content
How do I track QR scans?
QR Master tracks scans through the dynamic QR redirect step.
Current analytics context:

Current analytics context:
- Total and unique scan reporting
- Device type
- Location context
- Time-based scan activity

What security measures are in place?
QR Master uses standard protective controls that are visible in the current codebase.
Security-related controls:
Security-related controls:
- HTTPS/TLS encryption for all connections
- CSRF protection for relevant write actions
- Rate limiting on API routes
How does bulk QR creation work today?
QR Master currently supports bulk QR creation through spreadsheet upload in the Business plan.
Current bulk flow facts:
See the bulk QR workflow
Current bulk flow facts:
- CSV, XLS, and XLSX uploads are supported
- Up to 1,000 rows per upload
- Output is static QR codes, not dynamic tracking batches
See the bulk QR workflow
What are the best practices for printing QR codes?
For reliable scanning, follow these print-first basics:
- Minimum size around 2x2 cm for close-range scans
- Dark foreground on a light background
- Leave a quiet zone around the QR code
- Use SVG or a high-resolution PNG depending on the print workflow
Is the service privacy-conscious?
QR Master is built around minimal scanner data collection.
Privacy-related measures:
Read the privacy policy
Privacy-related measures:
- IP addresses are anonymized or hashed
- No scanner PII storage
Read the privacy policy
What is the difference between static and dynamic QR codes?
Static QR codes store the destination directly in the image and stay fixed. Dynamic QR codes route through QR Master so the destination can be changed later and scan analytics can be reviewed.
