Every guide is written around QRwaLink's actual static QR and WhatsApp-link features.
Images are normally hosted and linked rather than embedded. Public access, file size, responsive display, captions, alt text, ownership, and future replacement all matter. This field guide turns that decision into a reliable, accessible production workflow.
Read guideVideos are normally reached through a public URL. Account prompts, captions, bandwidth, autoplay expectations, app handoff, privacy, and durable hosting shape the experience. This field guide turns that decision into a reliable, accessible production workflow.
Read guideGoogle Drive links require deliberate sharing permissions. Files and folders must be tested while signed out and on mobile before the code is printed. This field guide turns that decision into a reliable, accessible production workflow.
Read guideDocument QR codes usually point to a public web or file URL. Choose formats, permissions, accessible alternatives, versioning, and ownership before publication. This field guide turns that decision into a reliable, accessible production workflow.
Read guideDistinguish sharing a spreadsheet from generating codes inside one. Protect sensitive cells, verify viewer permissions, and treat formulas or add-ons as separate systems. This field guide turns that decision into a reliable, accessible production workflow.
Read guideA form QR workflow must minimize mobile friction, explain data use, test sign-in requirements, preserve prefilled parameters when appropriate, and provide an accessible alternative. This field guide turns that decision into a reliable, accessible production workflow.
Read guidePlain-text QR codes can work offline after scanning, but capacity, character encoding, line breaks, density, legibility, and the absence of a clickable destination require careful choices. This field guide turns that decision into a reliable, accessible production workflow.
Read guideClick-to-chat links should contain a normalized international number and optional URL-encoded draft. The sender reviews the message; the link does not send it automatically. This field guide turns that decision into a reliable, accessible production workflow.
Read guideThe number must use its country calling code without local punctuation or a national trunk prefix. The receiving account and operating hours remain the publisher's responsibility. This field guide turns that decision into a reliable, accessible production workflow.
Read guidePrefilled WhatsApp text is visible in the URL, must be encoded correctly, should remain concise and editable, and must never contain secrets or imply consent. This field guide turns that decision into a reliable, accessible production workflow.
Read guideA business QR contact path should name the business, set expectations, use a maintained number, and distinguish a public click-to-chat URL from account or catalog features. This field guide turns that decision into a reliable, accessible production workflow.
Read guideCustomer-service links reduce the first step but do not replace staffing, triage, escalation, privacy controls, accessibility, or emergency contact routes. This field guide turns that decision into a reliable, accessible production workflow.
Read guideUse clickable WhatsApp links in mobile profiles and ads, reserving QR codes for physical or cross-device contexts. Platform review rules and measurement remain external dependencies. This field guide turns that decision into a reliable, accessible production workflow.
Read guideShort or branded links add a redirect provider and domain dependency. Direct wa.me URLs are transparent; custom links require ownership, security, expiry, and analytics review. This field guide turns that decision into a reliable, accessible production workflow.
Read guideDark modules on a light, predictable background are the safest baseline. Measure contrast, account for print shift and glare, and retest every color change. This field guide turns that decision into a reliable, accessible production workflow.
Read guideModule shapes and external frames can support branding if finder patterns, geometry, contrast, and quiet space remain intact. Decorative controls are not guarantees. This field guide turns that decision into a reliable, accessible production workflow.
Read guideTransparency delegates the background decision to every future placement. Use it only in controlled layouts with a light containment panel and a tested opaque fallback. This field guide turns that decision into a reliable, accessible production workflow.
Read guideSVG is useful for resolution-independent artwork, but correct geometry, color handling, view boxes, embedded logos, and print conversion still require validation. QRwaLink currently exports PNG and PDF, not SVG. This field guide turns that decision into a reliable, accessible production workflow.
