Question 1

Why does HoldQR say "Your QR code should never need to be reprinted"?

Accepted Answer

With static QR codes, the final destination URL is permanently encoded directly into the black-and-white pixel modules. If your website URL changes, a promotion expires, or someone makes a typo, the printed material is permanently broken and must be reprinted. With HoldQR Dynamic QR codes, the printed code points to a permanent, ultra-fast routing link on HoldQR. You can change where that link redirects anytime from your dashboard in under 5 seconds—without altering the printed QR code on your signs, packaging, or vehicles.

Question 2

How does HoldQR edge redirection work under the hood?

Accepted Answer

When a customer scans your HoldQR code, their phone sends an optical request to our global edge routing infrastructure (e.g. holdqr.com/q/slug). Our edge network resolves your active target URL with HTTP 302/307 redirects in under 30 milliseconds worldwide, forwarding the scanner to your destination instantly while recording anonymous telemetry (scan time, device OS, and approximate region).

Question 3

How quickly does a destination URL update take effect?

Accepted Answer

Instantly. As soon as you click "Save Changes" inside your HoldQR dashboard, the redirection target is updated immediately across our edge routing servers. Any customer scanning your printed code 1 second later will be directed to your new destination URL.

Question 4

Do HoldQR dynamic QR codes ever expire or stop working?

Accepted Answer

No. Unlike typical QR generator platforms that hold your printed materials hostage with $30–$50 monthly subscriptions and deactivate your QR codes if you cancel, HoldQR operates on a lifetime model. Your dynamic QR codes remain online permanently with zero monthly maintenance fees.

Question 5

How small can I safely print a QR code?

Accepted Answer

For handheld reading (such as business cards, flyers, and table tents held 10–14 inches away), the minimum absolute size is 2 x 2 cm (0.8 x 0.8 inches). For greater scanning distances (posters, billboards, storefronts), use the optical 10:1 distance-to-size formula: Distance divided by 10 equals the minimum QR code width. For example, a poster scanned from 2 meters (200 cm) away requires a QR code at least 20 cm wide.

Question 6

What is a QR quiet zone and why is it mandatory?

Accepted Answer

The quiet zone is the blank, unprinted margin surrounding the outer boundary of the QR code modules. According to ISO/IEC 18004 standards, the quiet zone must be at least 4 module widths on all four sides. If graphics, text, or crop marks bleed into this margin, smartphone camera optical sensors cannot distinguish where the QR code ends, causing scan failures.

Question 7

Should I send SVG or PNG to my commercial print shop?

Accepted Answer

Always send Vector SVG for professional commercial printing. Vector SVG files are mathematically defined paths that scale to any dimension—from a 1-inch product sticker to a 20-foot trade show banner—with razor-sharp clarity and zero raster pixelation. PNG is ideal for digital screens, websites, and quick desktop printers.

Question 8

How do I thoroughly test a QR code before printing 10,000 copies?

Accepted Answer

Follow our 4-step pre-flight checklist: 1) Download our printable Print Test Sheet to test physical calibrated sizes on paper. 2) Scan the proof with both an iOS Camera app and an Android Google Lens scanner under varied lighting. 3) Test from the actual expected distance. 4) Verify that your destination URL is secure (HTTPS) and mobile-responsive.

Question 9

Can I add my company logo without breaking scannability?

Accepted Answer

Yes! When you upload a custom logo or choose a platform emblem in HoldQR, our engine automatically switches the QR Error Correction Level to "H" (High), which allows up to 30% of the QR data modules to be covered or damaged while maintaining high optical readability. We also maintain a protective contrast border around your logo.

Question 10

Can I use custom brand colors, gradients, and shaped dots?

Accepted Answer

Yes. HoldQR includes an advanced Custom QR Studio that allows you to configure foreground linear gradients, rounded or dot modules, custom corner eye inner and outer shapes, and branded call-to-action frames (e.g. "SCAN ME", "FOLLOW ON INSTAGRAM", "VIEW MENU").

Question 11

What color combinations should I avoid?

Accepted Answer

Always ensure high optical contrast: dark foreground modules on a light background (minimum 4:1 contrast ratio). Never invert the code (e.g. white dots on dark yellow or light gray background) as many native camera scanners rely on dark-on-light optical edge detection. Use our built-in QR Contrast Checker to verify WCAG optical contrast before exporting.

Question 12

What is included in the $39 Lifetime Plan?

Accepted Answer

The HoldQR Lifetime Plan is a one-time purchase of $39 with zero recurring subscriptions. You receive: permanent dynamic QR codes that never expire, unlimited scans forever, vector SVG and high-resolution PNG exports, complete visual customization (logos, gradients, custom eyes, frames), real-time destination URL editing, anonymous scan telemetry, and full commercial usage rights.

Question 13

Are there monthly scan limits or overage charges?

Accepted Answer

None. Your codes can receive 10 scans or 10,000,000 scans—there are no scan limits, bandwidth caps, or unexpected monthly bills. Our edge infrastructure is built on ultra-lightweight distributed routing designed for massive scale.

Question 14

Can design agencies and freelancers use HoldQR for client projects?

Accepted Answer

Yes! You own full commercial distribution rights to all generated QR assets. You can print them on client merchandise, menus, signs, trade show displays, and product packaging with zero licensing royalties.

Question 15

What is your refund policy?

Accepted Answer

We offer a 30-day, no-questions-asked money-back guarantee. If HoldQR does not satisfy your workflow or printing requirements, contact support@holdqr.com within 30 days of purchase for a full refund.

Question 16

Help! I already printed materials with the wrong link. Can I fix it?

Accepted Answer

If you created a Dynamic QR code with HoldQR, simply log into your dashboard, click "Edit", type in the correct URL, and click "Save Changes". Your printed materials are fixed immediately without reprinting. If you printed a direct Static QR code (where the external URL is burned into the dots), the pixels cannot be altered optically; however, if you control that destination domain, you can configure a server-side redirect on your hosting server.

Question 17

Why is my printed QR code refusing to scan?

Accepted Answer

The top 5 culprits for scan failures are: 1) Missing Quiet Zone (graphics touching the outer edges). 2) Inadequate optical contrast (e.g. pastel colors or low contrast). 3) Glossy surface glare (light reflections blinding the camera lens). 4) The code was printed smaller than the 10:1 viewing distance threshold. 5) The destination URL is broken or returning a 404/500 error.

Question 18

How do I check whether an existing printed QR is static or dynamic?

Accepted Answer

Scan the code or upload an image to our free "Can I Change This QR?" diagnostic tool. If the raw decoded URL points to a redirect service or domain you manage, it is dynamic and can be redirected. If it points directly to an unmanaged final web address, it is hardcoded static.
