QR code glossary

Plain definitions of every term used in QRCode Suite docs, blog and dashboard. Linked from feature pages so search engines can resolve our terminology.

Last updated: May 11, 2026

A/B testing

Splitting scanners 50/50 between two destinations to compare conversion. Available on the Pro plan and above.

AEO / GEO

Answer Engine Optimization / Generative Engine Optimization — making content directly citable by ChatGPT, Perplexity, Claude and Google AI Overviews.

Bot detection

Automatic filtering of crawler and scanner traffic (25+ patterns) so analytics only counts real human scans.

Campaign

A grouping of QR codes that share a goal (launch, season, event). Campaigns roll scan and revenue metrics into a single report.

Conditional redirect

A redirect that resolves to different destinations based on rules — device type, country, time of day, or number of previous scans.

CSV export

Downloading scan and conversion data as a comma-separated file for use in Excel, Sheets, or BI tools. Available on Pro and above.

CTA band

A horizontal call-to-action section at the bottom of a marketing page. Used consistently across QRCode Suite templates.

Dynamic QR code

A QR code whose destination URL is a short redirect; the underlying target can be changed at any time without reprinting the code.

Email QR

A QR code that pre-fills an email recipient, subject and body when scanned.

Error correction

Built-in redundancy in a QR code (levels L 7%, M 15%, Q 25%, H 30%) that keeps the code readable even when partly obscured or damaged.

First-party analytics

Analytics where the data is collected and stored on your own infrastructure — no third-party SaaS sits between you and your scan data.

GA4 integration

Forwarding QR scan and conversion events to a Google Analytics 4 property as custom events with utm parameters preserved. Pro+.

GDPR

EU General Data Protection Regulation. QRCode Suite is GDPR-conscious by default: IP addresses are hashed, retention is configurable, and no raw personal data is sent to third parties.

Grace period

A 14-day window after a payment fails during which the plugin keeps working at full feature parity, giving the customer time to update billing.

Heatmap

Visual matrix showing scan density by hour, day, or geography. Helps identify peak campaign windows and high-performing regions. Business+.

hreflang

An HTML link annotation telling search engines which URL serves each language version of the same page. QRCode Suite emits hreflang for all 6 locales.

IP hashing

Replacing a visitor IP with a one-way SHA-256 hash before storage so the raw IP is never persisted; preserves uniqueness counting without holding personal data.

License key

The credential that unlocks paid features in the plugin. Format: QCS-LIVE-{PLAN}-{8}-{8}-{8}-{8}. Stored hashed, never plaintext.

Link Hub

A small landing page hosted on your own domain that bundles multiple links (menu, reorder, socials, vCard) reachable from a single QR scan.

llms.txt

A plain-text file at /llms.txt that gives AI crawlers a curated overview of a site's most relevant pages. QRCode Suite regenerates llms.txt and llms-full.txt at build time.

Logo QR code

A QR code with a brand logo overlaid in the centre. Higher error-correction levels (typically Q or H) compensate for the obscured modules.

Meta Pixel integration

Forwarding QR scan and conversion events to the Meta Pixel for Facebook/Instagram ad attribution. Pro+.

Multi-client workspace

A single Agency dashboard that lists every managed WordPress site as a separate client, with roles and isolated analytics.

Open Graph

A protocol (og:title, og:image, og:description) that controls how a URL renders when shared on social media and chat apps.

PDF QR code

A dynamic QR that resolves to a hosted PDF file (menu, brochure, manual). Replace the PDF without changing the printed code.

QR code

A two-dimensional matrix barcode that encodes text, URLs, or other data and can be scanned by a smartphone camera.

Reorder rate

Percentage of customers who place a second order via the scan-to-reorder QR within a defined window (commonly 30 or 90 days).

REST API

HTTP API exposed by QRCode Suite for programmatic QR creation, scan retrieval, and Link Hub management. Available on Business and Agency.

Scan rate

Number of scans per impression or per unit of distribution (per flyer, per package, per ad). The primary efficiency metric for printed QR.

Scan-to-reorder

A flow where a customer scans a QR on packaging or a receipt and is taken straight to a pre-filled WooCommerce cart with the same product.

Schema.org

A shared vocabulary (JSON-LD) for marking up content semantically (Product, FAQ, HowTo, Article, Organization). Search engines and AI engines parse it for rich answers.

Short URL

A short redirect link of the form /r/{slug} that resolves to a longer destination URL. Dynamic QR codes encode a short URL.

Site activation

Linking a license key to a specific WordPress site URL. Each plan allows a fixed number of activations (Free: 1, Pro: 1, Business: 5, Agency: 25).

SMS QR

A QR code that, when scanned, pre-fills an SMS to a chosen number with optional message text.

Speakable schema

A Schema.org extension that marks specific page sections (typically FAQs) as suitable for voice assistants and AI summary citations.

SSE (Server-Sent Events)

A one-way streaming protocol used to push real-time scan events to the QRCode Suite dashboard without polling. Business+.

Static QR code

A QR code whose target is encoded directly inside the matrix; the destination cannot be changed after the code is printed.

SVG export

Exporting a QR code as a vector SVG file — infinitely scalable, ideal for print at any size with no pixelation.

UTM attribution

Tagging the destination URL with utm_source, utm_medium and utm_campaign parameters so downstream analytics tools can identify which campaign drove a visit.

vCard

A digital business card format (.vcf). Scanning a vCard QR offers to save name, phone, email, address and company to the device's contacts.

Webhook

An HTTP POST your server receives when a scan or conversion happens, so external systems (CRM, ESP, Zapier) can react in real time. Available on Business+.

WhatsApp QR

A QR code that opens a WhatsApp chat with a chosen number, optionally pre-filled with a message.

White-label

Rebranding QRCode Suite UI (Link Hubs, PDF reports, multi-client dashboards) under the agency's own brand. Available on the Agency plan.

Wi-Fi QR

A QR code that encodes Wi-Fi SSID, password and security type so a phone joins the network on scan.

WooCommerce order attribution

Linking a WooCommerce order back to the QR scan that started the visit, so you can measure revenue and conversion rate per QR code.
