<h1>QR Marketing Toolkit</h1>
<h2>Overview</h2>
<p>QR Marketing Toolkit is a professional-grade QR code generator designed specifically for WEO Media's marketing team. Built to streamline the creation of branded, trackable QR codes for marketing campaigns, this tool combines powerful customization options with built-in analytics to measure campaign effectiveness.</p>
<h2>The Challenge</h2>
<p>WEO Media's marketing team needed a solution to:</p>
<ul>
<li><strong>Create branded QR codes</strong> that maintain visual consistency across campaigns</li>
<li><strong>Track engagement</strong> without relying on third-party services</li>
<li><strong>Export in multiple formats</strong> for various marketing materials</li>
<li><strong>Integrate UTM parameters</strong> for comprehensive campaign analytics</li>
<li><strong>Maintain simplicity</strong> for non-technical team members</li>
</ul>
<p>The existing QR generators either lacked customization options, didn't support tracking, or required expensive subscriptions for team usage.</p>
<h2>Technical Architecture</h2>
<h3>Frontend Stack</h3>
<pre><code class="language-typescript">// Next.js 14 with App Router for modern React architecture
// TypeScript for type safety and better developer experience
// Tailwind CSS for rapid UI development
// qr-code-styling for advanced QR customization
</code></pre>
<p>The application leverages Next.js 14's latest features:</p>
<ul>
<li><strong>App Router</strong> for improved routing and layouts</li>
<li><strong>Server Components</strong> where applicable for performance</li>
<li><strong>Dynamic Imports</strong> for code splitting</li>
<li><strong>Responsive Design</strong> optimized for desktop and mobile</li>
</ul>
<h3>QR Generation Engine</h3>
<p>The core QR generation uses a sophisticated approach with real-time customization:</p>
<pre><code class="language-typescript">// Simplified example of the QR generation system
interface QRConfig {
data: string
style: 'square' | 'rounded' | 'artistic'
colors: {
qr: string
corners: string
background: string
}
logo?: File
size: number
format: 'png' | 'svg' | 'jpeg' | 'pdf'
}
async function generateQR(config: QRConfig) {
// 1. Validate and prepare data
const url = ensureProtocol(config.data)
// 2. Apply UTM parameters if enabled
const trackableUrl = addUTMParameters(url, campaign)
// 3. Generate QR with custom styling
const qr = new QRCodeStyling({
data: trackableUrl,
dotsOptions: {
color: config.colors.qr,
type: getDotsType(config.style)
},
cornersSquareOptions: {
color: config.colors.corners,
type: getCornersType(config.style)
},
backgroundOptions: {
color: config.colors.background
},
imageOptions: config.logo ? {
source: config.logo,
margin: 10
} : undefined
})
// 4. Export in requested format
return await exportQR(qr, config.format)
}
</code></pre>
<h3>Brand Customization System</h3>
<p>The toolkit includes WEO Media's brand presets while allowing full customization:</p>
<ul>
<li><strong>Color Presets</strong>: Brand-approved color combinations</li>
<li><strong>Logo Integration</strong>: Automatic logo sizing and positioning</li>
<li><strong>Style Templates</strong>: Classic, Modern, and Artistic QR patterns</li>
<li><strong>Size Presets</strong>: Optimized for different use cases (business cards, posters, digital)</li>
</ul>
<h3>UTM Tracking Integration</h3>
<p>Built-in UTM parameter builder for comprehensive analytics:</p>
<pre><code class="language-typescript">// UTM parameter system with campaign presets
const campaignPresets = {
email_signature: {
source: 'email',
medium: 'signature',
campaign: 'employee_signatures'
},
print_material: {
source: 'print',
medium: 'qr_code',
campaign: 'print_marketing'
},
social_media: {
source: 'social',
medium: 'qr_code',
campaign: 'social_campaign'
}
}
function buildTrackableURL(baseUrl: string, utm: UTMParams) {
const url = new URL(baseUrl)
Object.entries(utm).forEach(([key, value]) => {
if (value) url.searchParams.set(`utm_${key}`, value)
})
return url.toString()
}
</code></pre>

<li><strong>Simplicity Scales</strong>: A focused tool beats a feature-packed one</li>
<li><strong>Tracking is Essential</strong>: What gets measured gets improved</li>
</ol>
<h2>Future Enhancements</h2>
