Upon scanning, users are instantly redirected to a specific link such as a website, video, social media, registration form, blog post, and more.Advantages of Using Link QR CodesEasy to Use & Access: Users simply open the camera → scan → access the link without typing.Time-Saving: No need to type long URLs — access in just 1–2 seconds.Fast & Effective Marketing: Print QR codes on flyers, packaging, posters to instantly boost traffic.Modern & Professional: Demonstrates your brand's innovation and tech-friendliness.Trackable & Analyzable: Some QR tools allow you to track scans, location, time, etc.Versatile for Sharing: Easily shared via print, email, social media, websites.Comparison Table: With vs. Without QR CodesCriteriaWith QR CodeWithout QR CodeLink AccessQuick scan, no typingMust type manually, prone to errorsUser ExperienceSmooth & convenientLess convenient, especially for seniorsMarketing EffectivenessEye-catching, modernLess impressive, easier to overlookIntegrationEasy to print on packaging, posters, social mediaMainly limited to online useTracking CapabilitiesYes (if dynamic QR)Not trackable2. Common Types of Link QR CodesWhat is a Static QR Code?A static QR code has fixed content encoded into the image. Once generated, it cannot be changed. All scans lead to the same information (e.g., a URL, text, or phone number).Example: You create a QR code for https://abc.com/sale2025 and print it on 10,000 flyers. If the promo changes, you can’t update the link.Key Features:Data is directly embedded in the imageWorks offlineCannot be edited after creationNo scan trackingFree with most QR toolsBest Use Cases:Use CaseWhy It's SuitableStatic info (PDF menus, business cards)No need to update or editOne-time-use materials or filesSimple, quick creation, no need for analyticsShort-term events with fixed infoCost-effective, bulk printing-friendlyNon-sensitive environmentsNo risk from changing or hidden infoWhat is a Dynamic QR Code?A dynamic QR code redirects via an intermediary URL (usually from a QR platform), allowing you to update the destination link anytime without reprinting the QR code.Example: You print a QR code on product packaging.

Frequently Asked Questions About Creating Link QR CodesDo QR Codes for Links Expire?It depends on the type of QR code used:Static QR Codes: Never expire — the link is permanently encoded in the QR. However, if the linked page is deleted or renamed, the code will no longer work.Dynamic QR Codes: Can have an expiration time or be turned on/off manually. Ideal for temporary campaigns.Example: You create a dynamic QR code for a promotion that ends on April 30, 2025. After that date, anyone scanning the code sees a message: "This promotion has ended — Thank you for your interest!"Are QR Codes secure?No, QR codes themselves are not secure — anyone who scans them can see the content. However, you can secure access to the content by:Using dynamic QR codes with passwords, scan limits, or expiration timesLinking to content that requires login or is encryptedExample: You generate a QR code that links to internal documents → use a dynamic QR code + password → only those with the password can access it.How many people can scan a QR Code at the same time?There is no limit to the number of people who can scan a QR code simultaneously. A single QR code can be scanned by hundreds, thousands, or even millions of users without affecting functionality — as long as the link remains active and is not restricted by the hosting server.Example: You print a QR code on a shopping mall poster → 100 people scan it within a minute and all can access the link normally.ConclusionA QR code for links is more than just a sharing tool — it's a “smart bridge” between your brand and your audience in the digital age.

Notes When Creating and Using QR CodesEven when you’ve mastered the process of creating QR codes for products, using them properly and avoiding common mistakes is essential to ensure the code works effectively and doesn’t cause any issues for consumers. Here are some important points to consider when creating QR codes for products:Clearly Define the Purpose of the QR CodeBefore creating the QR code, you need to answer the question: What is this QR code for?Is it leading to product information?Showing usage instructions?Linking to a promotional program?Or for traceability? Knowing the purpose will help you choose the correct encoding format (URL, vCard, text, etc.).Design the QR Code to Fit the BrandWhen creating a QR code for a product, take advantage of the customization options for color, borders, and logos to make the QR code recognizable for your brand.However, ensure good contrast between the background and the code. Avoid choosing very light colors or complicated backgrounds that could make scanning difficult.Choose a High-Resolution Print FormatWhen starting to create the QR code, selecting a high-resolution image format is critical. If the QR code is pixelated when printed, it may not be scannable.Recommendations:Use SVG, PDF, or PNG formats with a resolution of 300 DPI or higher.Avoid using screen captures or low-compression formats.Always Test the QR Code on Multiple Devices Before Mass PrintingBefore printing in bulk, test the QR code on various devices (iPhone, Android, mid-range phones) and using different QR code reader apps (like Zalo or default camera apps).This helps detect display issues, broken links, or scanning problems due to format conflicts.Avoid Overloading the QR Code with Too Much InformationA common mistake when creating QR codes for products is stuffing too much information into the code, making it complex and harder to scan.Solution: Only encode essential information. If you need to provide a lot of details (videos, images, documents), link to a URL that summarizes the content (landing page or detailed product page).Place the QR Code in an Easily Scannable Position and Correct SizeWhen printing the QR code, its placement on the packaging is important. Ensure it’s visible and placed in a location with a clean, clear background (e.g., near the brand logo).Avoid placing it in areas prone to being folded, smudged, or sticky, like the edges of labels.Use a Reliable QR Code Generator and Analytics SupportWhen applying QR codes, choose trusted tools like iCheckQR, Me-QR, which offer:Tracking scan counts and device usage.Ability to update content without changing the code.Ensuring data security and safe links.Avoid Using Untrustworthy Shortened LinksSome users shorten links (e.g., bit.ly) to save characters, but this can make users skeptical about security and cause the links to be blocked by some browsers or networks.Always use verified, secure links with SSL (https), preferably from your brand's domain.ConclusionCreating QR codes for products is not just a trend but an essential part of brand-building and customer engagement in the digital era. Mastering the process of creating QR codes will not only help businesses save costs, optimize the user experience, but also enhance brand credibility and protect products in the market.With the detailed steps and key considerations provided in this article, you can confidently design, implement, and integrate QR codes into your product packaging, documentation, or digital platforms in a professional manner.Start implementing QR codes for your products today so that each product not only sells but is also trusted and remembered by consumers.

Common mistakes to avoid when creating QR Code for documentsThe use of QR codes in document sharing is becoming an essential trend in today’s digital environment. However, to achieve optimal results, not everyone knows how to create QR codes for documents correctly and professionally.Here are important tips to avoid common mistakes and ensure the stability, security, and long-term usability of QR codes.Avoid expired links or oversized filesA common mistake when creating QR codes for documents is using temporary links or sharing excessively large files that take too long to open. This not only interrupts the user experience but also damages your business's credibility.Always use reliable storage platforms like Google Drive, OneDrive, or Dropbox to create fixed links (permalinks) for documents.Limit Smart Access Rights: Only allow "view" permissions, not "edit," unless necessary. This is crucial for any QR code document creation guide to protect the content.Compress Files If Necessary: Especially with large PDF files over 10MB, compress them before creating a QR code for Word or PDF documents.Avoid Using Temporary Platforms Like WeTransfer: Files will expire after a few days, leading to errors like "QR Code not configured for this document type."Design QR Code correctly for print and screenIn addition to knowing how to create QR codes for documents, it’s essential to pay attention to the size, color, and contrast of the QR code when placed in print or digital media. A poorly designed QR code may not scan properly or lose brand recognition.Recommended Size Chart (by usage location):Usage LocationMinimum Size (mm)NotesNamecard (Business Card)20mm x 20mmPrefer a white background, no image overlapBrochure/Flyer30mm x 30mmLeave a quiet zone around the codeBanner/Backdrop50mm x 50mm or largerHigh resolution, test at various distancesExpert Tip: When creating a QR code for a document, always test print versions in both color and black-and-white to check contrast levels and ensure it scans in low-light environments.5.
