Pindai Kode QR & Barcode

Bagaimana Cara Saya Memindai Kode QR atau Barcode?

Pemindaian sangat sederhana dengan pemindai berbasis web kami. Klik 'Mulai Kamera' untuk mengaktifkan kamera perangkat Anda, lalu pegang dengan stabil di atas kode QR atau barcode. Posisi kode dalam bingkai pemindaian dan tunggu deteksi otomatis - biasanya dalam 1-2 detik. Pemindai bekerja dengan kamera depan atau belakang ponsel Anda, dan Anda dapat beralih di antara keduanya menggunakan tombol pengalih kamera.

If you prefer not to use your camera, select 'Upload Image' mode and choose a saved photo containing a QR code or barcode from your device. Our scanner supports JPG, PNG, and WEBP formats and will automatically detect and decode any codes in the uploaded image. This method is perfect for scanning codes from screenshots, emails, or downloaded images.

Format Apa Saja yang Dapat Dibaca Pemindai Anda?

Apakah Anda sedang memindai produk ritel, label pengiriman, tiket acara, atau materi pemasaran, pemindai kami secara otomatis mengenali semua format ini tanpa memerlukan Anda untuk menentukan jenisnya.

Mengapa Pemindai Saya Tidak Berfungsi?

Jika pemindaian tidak berhasil, coba langkah pemecahan masalah berikut:

• Periksa Izin Kamera: Browser Anda perlu izin untuk mengakses kamera Anda. Jika ditolak, klik ikon kamera di bilah alamat browser Anda dan izinkan akses kamera, lalu segarkan halaman.
• Tingkatkan Pencahayaan: Pindai dalam kondisi pencahayaan yang baik. Hindari bayangan tajam, silau, atau sinar matahari langsung pada kode. Pencahayaan dalam ruangan atau cahaya alami yang terdistribusi bekerja dengan baik.
• Sesuaikan Jarak: Pegang kamera Anda 4-8 inci (10-20 cm) dari kode. Terlalu dekat menyebabkan kabur, terlalu jauh mengurangi resolusi. Kamera ponsel modern bekerja paling baik pada jarak ini.
• Pegang Stabil: Jaga agar kode dan kamera tetap diam selama pemindaian. Bahkan gerakan kecil dapat menghalangi deteksi. Letakkan tangan Anda di permukaan untuk stabilitas.
• Check Code Quality: Damaged, wrinkled, or low-quality printed codes may not scan. Try cleaning the surface or requesting a fresh code if possible.
• Try Another Browser: Some older browsers have limited camera support. Use Chrome, Firefox, Safari, or Edge for best results.
• Use Upload Mode: If camera scanning fails, take a photo with your phone's native camera app and upload it using our 'Upload Image' mode.

Is My Scan Data Private and Secure?

Yes, absolutely! Our scanner is designed with privacy as a top priority. All scanning happens entirely in your browser using JavaScript and the ZXing library - no data is ever sent to our servers or any third-party services. When you scan a QR code or barcode, the image processing and decoding occur locally on your device. The decoded content appears only on your screen and is never transmitted, stored, or logged anywhere.

This means you can scan sensitive information like WiFi passwords, payment codes, personal contact details, or confidential documents with complete confidence. Even your camera feed stays private - we don't record, save, or have access to any images. The scanner works offline once the page loads, so you can even disconnect from the internet and continue scanning. Your privacy is protected, and your data remains yours alone.

For maximum security when scanning codes in public or from untrusted sources, our scanner displays the content before any action is taken. This preview feature lets you review URLs, text, or contact information before clicking links or saving data, protecting you from malicious QR codes that might lead to phishing sites or harmful content.

Can I Scan Codes Without an App?

Yes! That's the beauty of our web-based scanner - no app installation required. Simply visit our website in any modern browser (Chrome, Firefox, Safari, Edge) on your smartphone, tablet, or computer with a webcam. Grant camera permissions when prompted, and you're ready to scan. This eliminates the need to download, install, and maintain separate scanning apps, saving storage space on your device.

Web-based scanning offers several advantages: instant access without downloads, automatic updates with new features and format support, compatibility across all devices and operating systems, and no storage space consumption. Most modern smartphones also have built-in QR code scanning in their native camera apps - just point and shoot. However, our scanner provides more detailed results, supports more barcode formats, and works with uploaded images.

What Happens After Scanning?

When a code is successfully scanned, our scanner displays the decoded content in the results panel. What happens next depends on the type of data:

• URLs & Links: Web addresses are displayed with a clickable link. Review the URL for safety before clicking to open it in a new tab.
• Plain Text: Text content is displayed with a copy button, allowing you to easily copy it to your clipboard for use elsewhere.
• Contact Information: vCard data shows formatted contact details with options to save to your contacts or copy individual fields.
• WiFi Credentials: Network name, password, and security type are displayed, making it easy to connect to the network.
• Product Codes: Retail barcodes show the numeric code with options to search for product information online.

All scan results remain visible in the results panel until you clear them or refresh the page. You can scan multiple codes in sequence, and each result is saved in the history for easy reference during your session.

How Can I Improve Scan Accuracy?

Follow these best practices for faster, more reliable scanning:

• Clean the Code Surface: Wipe away dust, fingerprints, or moisture from the code. Even minor smudges can interfere with scanning.
• Keep It Flat: Scan codes on flat surfaces when possible. Curved, folded, or wrinkled codes are harder to detect and decode.
• Maximize Contrast: Ensure good contrast between the code and its background. Black-on-white works best; faded or low-contrast codes may fail.
• Optimal Code Size: Codes should be at least 2x2 cm (0.8x0.8 inches) for reliable scanning. Very small codes require extremely steady hands and good cameras.
• Wait for Focus: Allow your camera a moment to auto-focus before expecting results. Modern phone cameras focus quickly but need a steady target.
• Minimize Angle: Scan codes straight-on rather than at extreme angles. Perpendicular positioning provides the clearest image.
• Use Good Cameras: Higher resolution cameras (most modern smartphones) scan faster and more reliably than older or low-quality cameras.

Can I Scan Multiple Codes at Once?

Our scanner processes one code at a time to ensure accuracy and provide clear results for each scan. When multiple codes appear in the camera view, the scanner detects and decodes the most prominent or centered code first. After scanning, the result is displayed in the results panel, and you can immediately scan the next code without any additional steps.

This sequential approach prevents confusion and allows you to review each code's content before moving to the next. All scan results remain visible in the results panel throughout your session, creating a scannable history. You can quickly scan dozens of codes one after another - each taking only 1-2 seconds - making it practical for inventory checks, ticket validation, or comparing products.

Does the Scanner Work on All Devices?

Yes! Our scanner is compatible with virtually all modern devices that have cameras and web browsers. This includes iPhones and iPads (iOS 11+), Android smartphones and tablets, Windows and Mac computers with webcams, Chromebooks, and Linux systems. The scanner automatically adapts to your device's screen size and camera capabilities, providing an optimized experience whether you're using a phone, tablet, or desktop computer.

For the best experience, we recommend using updated versions of Chrome, Firefox, Safari, or Edge browsers. Older browsers or devices may have limited camera API support. If you're using a computer without a webcam, you can still use the 'Upload Image' mode to scan codes from saved photos or screenshots. The scanner's responsive design ensures buttons, controls, and results are easily accessible regardless of your device size.
