QR code usage from 2021 to 2025<\/div><\/div>\n  <\/div>\n\n  <p>QR codes are scanned over a billion times a year worldwide. Every modern iPhone and Android phone reads them natively through the camera app \u2014 no special app needed. Creating one takes less than a minute.<\/p>\n\n  <p>This guide covers every method (online generators, Chrome, iPhone, Android, Canva, Google Sheets), every decision (static vs dynamic, which QR type, error correction levels), and every technical detail \u2014 including print specifications, sizing formulas, security risks, and the 8 most common failure modes.<\/p>\n\n  <!-- ==================== QUICK STEPS ==================== -->\n  <h2 id=\"quick-steps\">Quick steps: create a QR code in 60 seconds<\/h2>\n\n  <div class=\"g-steps\">\n    <div class=\"g-step\"><p><strong>Go to <a href=\"\/qr-code-generator\/\" class=\"ext\">pageloot.com\/qr-code-generator<\/a><\/strong> \u2014 no signup needed for static codes.<\/p><\/div>\n    <div class=\"g-step\"><p><strong>Choose your QR type<\/strong> \u2014 URL is the most common. Paste your link.<\/p><\/div>\n    <div class=\"g-step\"><p><strong>Customize (optional)<\/strong> \u2014 add your logo, change colors, pick a frame.<\/p><\/div>\n    <div class=\"g-step\"><p><strong>Download<\/strong> \u2014 SVG for print, PNG for digital. Scan it with your phone to verify.<\/p><\/div>\n  <\/div>\n\n  <p>That&#8217;s it for a free static QR code. If you need to edit the destination after printing, track scans, or upload files like PDFs \u2014 you need a <strong>dynamic QR code<\/strong>, which requires a plan. <a href=\"\/pricing\/\" class=\"ext\">Plans start at $7\/month<\/a> billed annually, or grab a <a href=\"\/lifetime-deal\/\" class=\"ext\">lifetime deal from $197<\/a> for permanent access.<\/p>\n\n<div style=\"position:relative;padding-bottom:56.25%;height:0;margin:28px 0;border-radius:12px;overflow:hidden\">\n  <iframe src=\"https:\/\/www.youtube.com\/embed\/PvdyGL1O134\" title=\"How to create a QR code\" frameborder=\"0\" allow=\"accelerometer;autoplay;clipboard-write;encrypted-media;gyroscope;picture-in-picture\" allowfullscreen style=\"position:absolute;top:0;left:0;width:100%;height:100%\"><\/iframe>\n<\/div>\n\n  <!-- ==================== HOW QR CODES WORK ==================== -->\n  <h2 id=\"how-qr-codes-work\">How QR codes actually work<\/h2>\n\n  <p>Understanding the mechanics helps you make better decisions about sizing, customization, and which type to use. Skip this if you just need to make one \u2014 but bookmark it for when a code breaks and you need to diagnose why.<\/p>\n\n  <p>A QR code is a two-dimensional matrix of black and white squares called <strong>modules<\/strong>. Each module represents a single bit of data. A small QR code (Version 1, 21\u00d721 modules) encodes about 17 characters. A large one (Version 40, 177\u00d7177 modules) can hold several thousand characters. There are 40 versions total \u2014 each adds 4 modules per side.<\/p>\n\n  <p>Not every module stores your data. The three large squares in the corners (<strong>finder patterns<\/strong>) tell the scanner where the code is and how it&#8217;s oriented. Alternating black-and-white strips (<strong>timing patterns<\/strong>) help calculate module size. Additional squares in larger codes (<strong>alignment patterns<\/strong>) correct for camera angle distortion. Format information stores the error correction level and masking pattern.<\/p>\n\n  <p>The actual data is encoded in one of four modes: numeric (0-9, most efficient), alphanumeric (0-9, A-Z, some symbols), byte (any ASCII character), or kanji. After encoding, the data goes through a <strong>Reed-Solomon error correction algorithm<\/strong> \u2014 the same math used in CDs, DVDs, and satellite communications \u2014 that generates redundant backup data. Both the original data and the redundancy are interleaved and spread across the code.<\/p>\n\n  <h3>Error correction levels: L, M, Q, H<\/h3>\n\n  <p>This is why QR codes still scan when they&#8217;re scratched, dirty, or have a logo covering the center:<\/p>\n\n  <table class=\"g-tbl\">\n    <thead><tr><th>Level<\/th><th>Recovery<\/th><th>Best for<\/th><th>Tradeoff<\/th><\/tr><\/thead>\n    <tbody>\n      <tr><td><strong>L (Low)<\/strong><\/td><td>~7%<\/td><td>Clean environments, digital displays, maximum data capacity<\/td><td>Smallest code, least damage tolerance<\/td><\/tr>\n      <tr><td><strong>M (Medium)<\/strong><\/td><td>~15%<\/td><td>General purpose \u2014 the most common default<\/td><td>Good balance of size and resilience<\/td><\/tr>\n      <tr><td><strong>Q (Quartile)<\/strong><\/td><td>~25%<\/td><td>Printed materials in moderate-wear environments<\/td><td>Larger code, good damage tolerance<\/td><\/tr>\n      <tr><td><strong>H (High)<\/strong><\/td><td>~30%<\/td><td>Codes with logos, outdoor use, factory floors, packaging<\/td><td>Largest code, maximum resilience<\/td><\/tr>\n    <\/tbody>\n  <\/table>\n\n  <p>When you add a logo to the center of a QR code, you&#8217;re physically covering modules \u2014 making them unreadable. A typical center logo covers 10-20% of the module area. At Level H (30% recovery), the code has enough redundancy to reconstruct the covered data. At Level M (15%), a logo may work in a lab but fail in the real world where scratches and fading pile on. Most generators (including Pageloot) automatically switch to Level H when you upload a logo.<\/p>\n\n  <h3>QR codes vs barcodes<\/h3>\n\n  <p>Traditional barcodes (UPC, EAN) are one-dimensional \u2014 they store data in a single line of varying-width bars, typically encoding 8-13 digits. QR codes are two-dimensional \u2014 they store data in a grid, encoding up to 4,296 alphanumeric characters. Barcodes require a laser scanner; QR codes work with any smartphone camera. For product identification at checkout, barcodes are fine. For anything involving consumer interaction \u2014 marketing, menus, contact sharing, file access \u2014 QR codes are the standard.<\/p>\n\n  <!-- ==================== STATIC VS DYNAMIC ==================== -->\n  <h2 id=\"static-vs-dynamic\">Static vs dynamic: the decision that changes everything<\/h2>\n\n  <p>This is the single most important decision when creating a QR code. Get it wrong and you&#8217;ll either pay for something you don&#8217;t need \u2014 or end up reprinting materials because you can&#8217;t change a baked-in URL.<\/p>\n\n  <div class=\"g-2col\">\n    <div class=\"g-col g-col-free\">\n      <h4>Static QR code \u2014 free, permanent<\/h4>\n      <p>The destination URL is encoded directly into the QR pattern. Once created, it can <strong>never be changed<\/strong>. Doesn&#8217;t need a server, subscription, or intermediary. Works forever, even if the QR provider shuts down.<\/p>\n    <\/div>\n    <div class=\"g-col g-col-paid\">\n      <h4>Dynamic QR code \u2014 editable, trackable<\/h4>\n      <p>Contains a short redirect URL (like <code>qr.pageloot.com\/abc123<\/code>) that points to the provider&#8217;s server. You can <strong>change the destination anytime<\/strong> without reprinting. The provider tracks every scan: location, device, time. Requires an active plan.<\/p>\n    <\/div>\n  <\/div>\n\n  <h3>When to use static<\/h3>\n  <p>Use static when the destination will never change: a business website URL, a Wi-Fi password, a fixed email address, contact details on a vCard, or a one-time event where you won&#8217;t need analytics. Static codes are free and independent \u2014 they work even if the generator disappears tomorrow.<\/p>\n\n  <h3>When to use dynamic<\/h3>\n  <p>Use dynamic when: you might need to change where the code points after printing, you want scan analytics (when, where, what device), you&#8217;re linking to files (PDF, image, audio) that might be updated, you&#8217;re running a time-limited campaign, or you&#8217;re managing codes for clients who need scan reports.<\/p>\n\n  <div class=\"g-callout\">\n    <strong>The trap to watch for:<\/strong> Some generators create dynamic codes by default during &#8220;free&#8221; trials \u2014 then deactivate them after 7-14 days. If you printed materials during the trial, your codes die unless you pay. This is documented across thousands of Trustpilot reviews for platforms like QR.io ($35\/month to reactivate), QRFY (7-day trial), and QR Code Generator Pro (14-day trial, 1.5 stars across 9,220 reviews). Pageloot clearly labels the 14-day trial. If you only need static codes, use our <a href=\"\/qr-code-generator\/\">free QR code generator<\/a> \u2014 no trial, no expiry, no signup.\n  <\/div>\n\n  <h3>The provider lock-in reality<\/h3>\n  <p>Dynamic QR codes have a catch most guides don&#8217;t mention: <strong>your codes are permanently tied to the provider&#8217;s servers<\/strong>. The redirect URL baked into the QR pattern can never be changed \u2014 it&#8217;s physically encoded in the printed code. If you switch providers, every printed material needs a new code. This means billing practices, refund policies, and long-term viability matter more than for most SaaS tools. A <a href=\"\/lifetime-deal\/\" class=\"ext\">lifetime deal<\/a> eliminates this risk by guaranteeing permanent access at a fixed one-time price.<\/p>\n\n  <!-- ==================== METHOD 1 ==================== -->\n  <h2 id=\"method-online\">Method 1: Online QR code generator (most flexible)<\/h2>\n\n  <p>Online generators are the most flexible \u2014 they support multiple QR types, customization, logo uploads, and (for dynamic codes) editing and tracking. <a href=\"\/qr-code-generator\/\" class=\"ext\">Pageloot&#8217;s generator<\/a> works on any device with no install.<\/p>\n\n  <h3>Create a free static QR code<\/h3>\n\n  <div class=\"g-steps\">\n    <div class=\"g-step\"><p><strong>Go to <a href=\"\/qr-code-generator\/\" class=\"ext\">pageloot.com\/qr-code-generator<\/a><\/strong> \u2014 no account needed.<\/p><\/div>\n    <div class=\"g-step\"><p><strong>Select your QR code type.<\/strong> Default is URL \u2014 paste any web address.

For offline use cases (Wi-Fi, contacts), choose the specific type so the phone handles it natively.<\/p>\n\n  <!-- ==================== CUSTOMIZE ==================== -->\n  <h2 id=\"customize\">How to customize your QR code (without breaking it)<\/h2>\n\n  <p>Branded QR codes get <strong>up to 80% more scans<\/strong> than generic black-and-white squares. But every customization affects scannability.<\/p>\n\n  <h3>Contrast is non-negotiable<\/h3>\n  <p>Foreground (dots) must be darker than background. Minimum contrast ratio: <strong>4:1<\/strong>. Dark blue or black on white is safest. Don&#8217;t invert (white on dark) \u2014 fails more often on reflective surfaces and with older phones.<\/p>\n\n  <h3>Logo rules<\/h3>\n  <p>Your logo can cover up to <strong>30% of the center<\/strong> at error correction Level H. Generators switch to Level H automatically when you upload a logo. If scanning fails after adding a logo, it&#8217;s too large.<\/p>\n\n  <h3>What to avoid<\/h3>\n  <p>Gradients on dots. Pastel-on-pastel color pairs. Anything covering the three corner squares (finder patterns). Decorative borders that encroach on the quiet zone. Round shapes that crop the code boundary.<\/p>\n\n  <!-- ==================== PRINT SPECS ==================== -->\n  <h2 id=\"print-specs\">Print specifications: sizes, formats, and materials<\/h2>\n\n  <p>This section prevents expensive reprints. Every QR code that &#8220;doesn&#8217;t work&#8221; in the real world failed because of a sizing, format, or material problem.<\/p>\n\n  <h3>Minimum sizes by material<\/h3>\n  <table class=\"g-tbl\">\n    <thead><tr><th>Material<\/th><th>Minimum<\/th><th>Recommended<\/th><th>Why<\/th><\/tr><\/thead>\n    <tbody>\n      <tr><td>Business card<\/td><td>1.5 \u00d7 1.5 cm<\/td><td>2 \u00d7 2 cm<\/td><td>Close-range, controlled lighting<\/td><\/tr>\n      <tr><td>Flyer \/ A4<\/td><td>2 \u00d7 2 cm<\/td><td>3 \u00d7 3 cm<\/td><td>Hand-held, easy phone positioning<\/td><\/tr>\n      <tr><td>Table tent<\/td><td>3 \u00d7 3 cm<\/td><td>4 \u00d7 4 cm<\/td><td>Angled surface, varying distance<\/td><\/tr>\n      <tr><td>Poster (indoor)<\/td><td>5 \u00d7 5 cm<\/td><td>8 \u00d7 8 cm<\/td><td>Scan distance 30-100 cm<\/td><\/tr>\n      <tr><td>Banner \/ signage<\/td><td>10 \u00d7 10 cm<\/td><td>15+ cm<\/td><td>Scan distance 1-3 meters<\/td><\/tr>\n      <tr><td>Billboard<\/td><td>30 \u00d7 30 cm<\/td><td>50+ cm<\/td><td>Scan distance 3-10+ meters<\/td><\/tr>\n      <tr><td>Product packaging<\/td><td>1.5 \u00d7 1.5 cm<\/td><td>2.5 \u00d7 2.5 cm<\/td><td>Small surface, close scan<\/td><\/tr>\n    <\/tbody>\n  <\/table>\n\n  <p><strong>The 10\u00d7 rule:<\/strong> a QR code scans from roughly <strong>10\u00d7 its width<\/strong>. 3 cm code \u2192 ~30 cm. 10 cm \u2192 ~1 meter. 50 cm billboard \u2192 ~5 meters.<\/p>\n\n  <h3>File formats<\/h3>\n  <p><strong>SVG for print \u2014 always.<\/strong> Vector, scales infinitely.

But real-world failures happen constantly. Here are the 8 most common failure modes.<\/p>\n\n  <h3>1. Too small for scanning distance<\/h3>\n  <p>The #1 failure. A 2 cm code on a poster 2 meters away can&#8217;t be resolved by a phone camera. Use the 10\u00d7 rule.<\/p>\n\n  <h3>2. Insufficient contrast<\/h3>\n  <p>Light gray on white. Yellow on cream. Scanners need minimum 4:1 contrast ratio.<\/p>\n\n  <h3>3. URL changed or deleted<\/h3>\n  <p>Static codes encode URLs permanently. If the URL breaks, the code leads to nothing. Dynamic codes let you redirect anytime.<\/p>\n\n  <h3>4. Subscription expired<\/h3>\n  <p>Dynamic codes route through the provider&#8217;s server. Subscription lapses = <strong>every printed code dies simultaneously<\/strong>. A <a href=\"\/lifetime-deal\/\" class=\"ext\">lifetime deal<\/a> eliminates this risk.<\/p>\n\n  <h3>5. Cropped quiet zone<\/h3>\n  <p>Designer crops the blank border. Scanner can&#8217;t find the boundary. Keep 4 modules of space on all sides.<\/p>\n\n  <h3>6. Too much data in a static code<\/h3>\n  <p>More data = more modules = denser, harder-to-scan code. Use a URL shortener or dynamic code for long URLs.<\/p>\n\n  <h3>7. Low-resolution for print<\/h3>\n  <p>200\u00d7200px PNG stretched to poster size = blurry module edges. Always SVG for print.<\/p>\n\n  <h3>8. Design over finder patterns<\/h3>\n  <p>The three corner squares are essential for scanning. Don&#8217;t place anything over them.<\/p>\n\n  <div class=\"g-tip\">\n    <strong>The one-minute test:<\/strong> Before printing, scan with at least two different phones (iPhone + Android) in the actual lighting conditions. If it takes more than 2 seconds to scan, fix it before printing.\n  <\/div>\n\n  <!-- ==================== SECURITY ==================== -->\n  <h2 id=\"security\">QR code security: quishing and how to stay safe<\/h2>\n\n  <p><strong>&#8220;Quishing&#8221;<\/strong> (QR code phishing) became a mainstream cybersecurity concern in 2025. Attackers place counterfeit QR codes over legitimate ones \u2014 on parking meters, restaurant tables, flyers \u2014 to redirect scanners to malicious websites. The FBI and multiple national agencies issued public warnings in 2024-2025. Only 39% of consumers can reliably identify a malicious QR code.<\/p>\n\n  <h3>If you&#8217;re scanning<\/h3>\n  <p>Check for sticker overlays \u2014 physical overlays are the most common attack. Use your phone&#8217;s built-in camera (shows URL preview before opening). If the preview URL looks suspicious, don&#8217;t tap.<\/p>\n\n  <h3>If you&#8217;re creating<\/h3>\n  <p>Use <strong>branded QR codes<\/strong> with your logo and colors \u2014 harder to replicate convincingly. Include a CTA describing where the code leads (&#8220;Scan for our menu at restaurant-name.com&#8221;). For physical placements, consider tamper-evident materials.<\/p>\n\n  <!-- ==================== BEST PRACTICES ==================== -->\n  <h2 id=\"best-practices\">Best practices for placement and scanning<\/h2>\n\n  <h3>Always include a call to action<\/h3>\n  <p>&#8220;Scan for menu&#8221;, &#8220;Scan for 20% off&#8221;, &#8220;Scan to connect on Wi-Fi&#8221; \u2014 tell people what they get. <a href=\"\/qr-code-generator\/\" class=\"ext\">Pageloot&#8217;s generator<\/a> includes frame templates with customizable CTA text.<\/p>\n\n  <h3>Place at natural phone height<\/h3>\n  <p>Between waist and eye level, angled slightly toward the scanner. Ankle-level and above-head codes get fewer scans.<\/p>\n\n  <h3>One code, one destination<\/h3>\n  <p>Link directly to the specific page, form, or file. Don&#8217;t link to your homepage. Fewer taps after scan = higher completion.<\/p>\n\n  <h3>Mobile-optimize the destination<\/h3>\n  <p>100% of scans happen on mobile. Text readable without zooming, tappable buttons, loads in under 3 seconds.<\/p>\n\n  <h3>Track with dynamic codes<\/h3>\n  <p>Static tells you nothing. Dynamic shows scan counts, time, location, device. For any marketing use, <a href=\"\/pricing\/\" class=\"ext\">dynamic codes are the minimum<\/a>.<\/p>\n\n  <h3>Accessibility<\/h3>\n  <p>Always provide a short URL below the code in readable text. Use colorblind-safe colors (avoid red-green). Blue-on-white and black-on-yellow work for all common forms of color vision deficiency.<\/p>\n\n  <!-- ==================== REAL COST ==================== -->\n  <h2 id=\"real-cost\">What nobody tells you: the real cost of a failed QR code<\/h2>\n\n  <p>Most guides treat failures as minor inconveniences. In practice, a broken QR code on printed materials creates cascading costs.<\/p>\n\n  <p><strong>The reprinting math:<\/strong> 500 business cards at $0.10 = $50. 1,000 brochures at $0.50 = $500. 5,000 product labels at $0.05 = $250. If the QR code fails \u2014 wrong URL, expired trial, cancelled subscription, bad contrast \u2014 the entire run is waste. The code costs $0-7\/month. The materials cost 10-100\u00d7 more.<\/p>\n\n  <p><strong>The trial trap math:<\/strong> QR.io&#8217;s &#8220;free&#8221; trial deactivates codes after 7 days. If you printed 200 business cards ($60) and they die, reactivation is $35\/month ($420\/year). Year-one cost for &#8220;free&#8221;: $480. QRFY works the same with a ~$123 minimum reactivation.<\/p>\n\n  <p><strong>Bottom line:<\/strong> the QR generator is the cheapest component. Materials, design time, and distribution are the expensive parts. Spending $7\/month (or $197 lifetime) on a reliable generator is the cheapest insurance against wasting hundreds in printed materials.<\/p>\n\n  <!-- ==================== CTA ==================== -->\n  <div class=\"g-cta\">\n    <p>Ready to create your QR code?<\/p>\n    <a href=\"\/qr-code-generator\/\" class=\"g-btn\">Free QR code generator \u2192<\/a>\n    <a href=\"\/lifetime-deal\/\" class=\"g-btn g-btn-w\">Lifetime deal from $197 \u2192<\/a>\n  <\/div>\n\n<\/div><!-- end pg-guide -->\n\n<h2 id=\"faq\">Frequently asked questions<\/h2>\n\n\n\n<div class=\"schema-faq wp-block-yoast-faq-block\"><div class=\"schema-faq-section\" id=\"faq-question-1778659211573\"><strong class=\"schema-faq-question\">Is it free to create a QR code?<\/strong> <p class=\"schema-faq-answer\">Static QR codes are free \u2014 Pageloot and several other generators let you create them without signup or payment. Dynamic QR codes (editable, trackable) require a paid plan, typically $7-35\/month. Pageloot offers a lifetime deal from $197 for permanent dynamic code access.<\/p> <\/div> <div class=\"schema-faq-section\" id=\"faq-question-1778659276204\"><strong class=\"schema-faq-question\">Do QR codes expire?<\/strong> <p class=\"schema-faq-answer\">Static QR codes never expire \u2014 the data is baked into the pattern permanently. Dynamic QR codes stay active as long as your subscription is active. If you cancel, the redirect stops working and printed codes go dead. Some generators deactivate dynamic codes after a 7-14 day trial without clear warning.<\/p> <\/div> <div class=\"schema-faq-section\" id=\"faq-question-1778659285006\"><strong class=\"schema-faq-question\">Can I change where my QR code points after printing?<\/strong> <p class=\"schema-faq-answer\">Only if it&#8217;s a dynamic QR code. Static codes encode the destination permanently \u2014 once printed, it can never be changed. Dynamic codes use a redirect through the provider&#8217;s server, so you can update the destination URL, swap a PDF, or redirect to a new page without reprinting anything.<\/p> <\/div> <div class=\"schema-faq-section\" id=\"faq-question-1778659292815\"><strong class=\"schema-faq-question\">What size should a QR code be for printing?<\/strong> <p class=\"schema-faq-answer\">Minimum 2\u00d72 cm for business cards and hand-held materials. Use the 10\u00d7 rule: a QR code can be scanned from roughly 10 times its width. A 3 cm code scans from ~30 cm. A 10 cm code scans from ~1 meter. For billboards, minimum 30\u00d730 cm.<\/p> <\/div> <div class=\"schema-faq-section\" id=\"faq-question-1778659304777\"><strong class=\"schema-faq-question\"><strong>Can I put a logo in my QR code?<\/strong><\/strong> <p class=\"schema-faq-answer\">Yes \u2014 most generators support center logo placement covering up to 30% of the code area. The code&#8217;s error correction (Level H) compensates for the covered modules. If scanning fails after adding a logo, reduce the logo size.<\/p> <\/div> <div class=\"schema-faq-section\" id=\"faq-question-1778659314222\"><strong class=\"schema-faq-question\">What&#8217;s the difference between a QR code and a barcode?<\/strong> <p class=\"schema-faq-answer\">Barcodes are one-dimensional (a line of bars encoding 8-13 digits, read by laser scanners). QR codes are two-dimensional (a grid encoding up to 4,296 characters, read by any smartphone camera). QR codes hold far more data and support URLs, files, contact info, and interactive content.<\/p> <\/div> <div class=\"schema-faq-section\" id=\"faq-question-1778659324031\"><strong class=\"schema-faq-question\">Why is my QR code not scanning?<\/strong> <p class=\"schema-faq-answer\">The most common causes: code is too small for the scanning distance, insufficient contrast between dots and background (minimum 4:1 ratio), the quiet zone (blank border) was cropped, the URL was deleted or changed (static codes), or the subscription expired (dynamic codes). Test with two different phones before printing.<\/p> <\/div> <div class=\"schema-faq-section\" id=\"faq-question-1778659331974\"><strong class=\"schema-faq-question\">What file format should I use for printing QR codes?<\/strong> <p class=\"schema-faq-answer\">SVG (vector format) \u2014 always. SVG scales to any size without pixelation. A QR code downloaded as SVG prints perfectly from a business card to a billboard. Use PNG only for digital (web, email, social). If you must use PNG for print, download at minimum 1000\u00d71000px.<\/p> <\/div> <div class=\"schema-faq-section\" id=\"faq-question-1778659340398\"><strong class=\"schema-faq-question\">Are QR codes safe to scan?<\/strong> <p class=\"schema-faq-answer\">Generally yes, but QR phishing (&#8220;quishing&#8221;) is a growing concern. Attackers place fake QR stickers over legitimate ones to redirect to malicious sites. Use your phone&#8217;s built-in camera (it shows a URL preview before opening). Check for physical sticker overlays. Avoid scanning codes on parking meters and unsolicited mail without verifying.<\/p> <\/div> <div class=\"schema-faq-section\" id=\"faq-question-1778659349292\"><strong class=\"schema-faq-question\"><strong>Can I create QR codes in bulk?<\/strong><\/strong> <p class=\"schema-faq-answer\">Yes.
