A: QR Code Scan Kit is a QR code scanner and barcode scanner for iPhone and iPad, made by BUILDLANES. It reads QR codes and 16 barcode formats, shows where a link really goes before it opens, joins Wi-Fi in one tap, and makes QR codes and barcodes. Scanning works offline, there is no account, and scans stay on the phone. Q: Who makes QR Code Scan Kit? A: BUILDLANES, a small app studio in India. Support is by email at support@buildlanes.com. Q: Which devices does it work on? A: iPhone and iPad with iOS 17 or later. An Android version is also made by BUILDLANES. Q: Which languages is the app in? A: 13 languages: English, German, Spanish, French, Italian, Portuguese (Brazil), Japanese, Korean, Chinese (Traditional), Arabic, Indonesian, Thai, Turkish. The app follows your phone's language. Q: Do I need an account? A: No. There is no sign-up and no login. Your scans, history and the codes you make stay on your phone. Q: Do I need a QR code scanner app on iPhone? A: For a code you trust, the iPhone Camera app is enough: point it at the code and tap the link. A scanner app is worth it when you want to see the full address before a link opens, read shop barcodes, scan codes from photos or keep a history. QR Code Scan Kit does those things for free, with no account and no third-party ads. Our comparison page shows what each option can and can't do. Q: Which barcodes can QR Code Scan Kit read? A: QR codes and 16 barcode formats: Micro QR, EAN-13, EAN-8, UPC-A, UPC-E, ISBN, Code 128, Code 39, Code 93, ITF, ITF-14, Codabar, GS1 DataBar, Data Matrix, PDF417, Aztec. Q: Can it scan a QR code from a screenshot or a photo? A: Yes. Tap Photos in the scanner and pick the picture. It finds every QR code and barcode in it, so codes sent in a chat or saved from a website work too. Q: Does it work without internet? A: Yes. Codes are read on the phone, so scanning works offline. Only extras need a connection: product details from Open Food Facts and link previews. Q: Can it scan many barcodes in a row? A: Yes. Batch scan keeps reading code after code, and scanning the same code again counts one more, so you can count stock. Export the list as a CSV file that opens in Excel, Numbers or Google Sheets. Q: Can I type a barcode number by hand? A: Yes. If a label is torn or won't scan, type the digits under the barcode and the app looks it up the same way. Q: How do I connect to Wi-Fi with a QR code? A: Scan the Wi-Fi QR code and tap Join network. The app reads the network name and password from the code and your iPhone joins, so you never type the password. Q: Is it safe to scan a QR code? A: Scanning itself is safe; the risk is the link a code opens. Fake QR codes (quishing) send people to look-alike login or payment pages. QR Code Scan Kit shows the real address before anything opens and warns about common tricks such as look-alike letters, hidden redirects, a bare IP address or an app installer file. It never calls a link "safe": if a code asks you to log in or pay when you didn't expect it, don't. Q: How can I tell if a QR code is fake? A: Look for a sticker placed over another code, a link that doesn't match the business, a short link that hides where it goes, spelling tricks in the site name, and pages that rush you to pay or log in. Our guide on spotting fake QR codes lists every sign and what to do if you were caught. Q: Does the app check links on a server? A: No. The risky-link check runs on your phone. If you leave link previews on, the app loads the scanned website to show a preview, like any visit; links the check marks as dangerous are never loaded. You can turn previews off in Settings. Q: Can I make my own QR code with it? A: Yes. The built-in QR code generator makes codes for links, text, Wi-Fi, contacts, email, phone, SMS, events and places, and you can add your colours, a logo, a frame and a caption. Q: Do the QR codes it makes expire? A: No. They are static QR codes: the information is inside the code itself, so they never expire, need no account to keep working, and still work if you delete the app. The trade-off: you can't change a static code after you print it. Q: Can it make dynamic QR codes or count scans? A: No. QR Code Scan Kit only makes static codes. It has no dynamic codes, no scan tracking and no web dashboard. Q: Can it make barcodes? A: Yes: EAN-13, UPC-A, UPC-E, EAN-8, Code 128, Code 39, Code 93, ITF-14, ITF, Codabar, Data Matrix, PDF417 and Aztec, with the check digit added for you. Export as PNG or SVG, or print. Q: Can it make a WhatsApp or Instagram QR code? A: Yes. Social codes open a WhatsApp chat or an Instagram, YouTube, Facebook, X, LinkedIn or Telegram profile, with that network's logo in the middle. Q: What does the food check show? A: Scan a food barcode to see its health grade (A to E), sugar, fat and salt levels, how processed it is and its additives, from Open Food Facts, a free public database. Coverage varies by country and only listed products show up. It is a guide to compare products, not medical, diet or allergy advice. Q: Does it show allergens, halal status or prices? A: No. The app doesn't check allergens, gluten or halal status and doesn't look up prices. Q: Where does the product information come from? A: From Open Food Facts (and Open Beauty Facts for cosmetics), free public databases anyone can improve. Only the barcode number is sent to look the product up. If a product is missing or wrong, it can be fixed at openfoodfacts.org. Q: Is QR Code Scan Kit free? A: Free to download. Some extra features are part of Scan Kit Pro — you'll see the options and prices in the app. There is no account to create. Q: What is Scan Kit Pro? A: An optional in-app purchase that adds extra features. The app shows what it includes and the price in your own currency before you confirm, and you can keep using the app without it. Q: How do I restore a purchase on a new phone? A: In the app, open Settings and tap Restore, signed in with the same Apple Account (or Google account on Android) you bought with. Q: How do I cancel or get a refund? A: Purchases are handled by Apple and Google. On iPhone open Settings, tap your name, then Subscriptions; on Android open Google Play, then Payments & subscriptions. Refunds are requested from Apple or Google too. The support page has the steps. Q: Does the app have ads? A: No third-party ads and no ad networks. The app may show small cards for our own products. Q: Does QR Code Scan Kit collect my data? A: Your scans, history and the codes you make stay on your phone, and nothing you scan is sent to us. The app sends anonymous usage stats and crash reports (never what you scan) to PostHog on EU servers to fix bugs, and you can turn them off in Settings with "Share usage anonymously". Purchases go through Apple, and RevenueCat keeps your purchase status under a random ID. The privacy policy lists every detail. Q: Does it track me or use my advertising ID? A: No. The app doesn't use the advertising ID (IDFA), shows no tracking prompt and doesn't track you across other companies' apps or websites. Q: What leaves my phone when I scan a product? A: Only the barcode number, sent to Open Food Facts (or Open Beauty Facts) to look the product up. Like any web request, they see your IP address. Photos and scan history are never uploaded. ## Common questions about QR codes and barcodes Q: How do I scan a QR code with my phone? A: Open the camera, point it at the code for a second and tap the link that appears. On iPhone the Camera app does this (also the Code Scanner control in Control Center); on Android use the camera or Google Lens. QR Code Scan Kit also shows the real address and warning signs before anything opens. Guide: https://qrcodescankit.com/blog/how-to-scan-qr-code-iphone/ Q: Can you scan a QR code without an app? A: Yes. The iPhone Camera app and most Android camera apps read QR codes on their own, and Google Lens reads them too. A scanner app adds things like link checks, history and barcode support. Q: Where is the QR code scanner on my phone? A: On iPhone it is built into the Camera app, and there is a Code Scanner control you can add to Control Center. On Android it is in the camera app or Google Lens (in the Google app and the camera). Q: Do I need a QR code scanner app? A: Not for a code you trust: the phone camera is enough. A scanner app helps when you want to check a link before it opens, keep a history, scan product barcodes or scan from a photo. Q: Is a QR code scanner free? A: The scanner built into iPhone and Android cameras is free. QR Code Scan Kit is free to download, with no account. Q: Can I scan a QR code from a picture or screenshot? A: Yes. In QR Code Scan Kit tap Photos and pick the picture; Google Lens can read a code in a photo too. On a computer, the free QR code decoder reads an image in the browser without uploading it: https://qrcodescankit.com/tools/qr-code-decoder/. Guide: https://qrcodescankit.com/blog/scan-qr-code-from-screenshot/ Q: How do I scan a QR code that is on my own phone screen? A: Take a screenshot, then open it in a scanner that reads photos (QR Code Scan Kit's Photos button, or Google Lens). Or open the image on another device and scan it with your camera. Guide: https://qrcodescankit.com/blog/scan-qr-code-from-screenshot/ Q: Can I scan a QR code with Google? A: Yes. Google Lens, in the Google app, Chrome and many Android cameras, reads QR codes from the camera or from a picture. Q: Are QR codes safe to scan? A: Scanning itself is safe; the risk is the link a code opens. Fake QR codes (quishing) send people to look-alike payment or login pages. Check the real address before you open it and never enter a password or card number from a code you didn't expect. Guide: https://qrcodescankit.com/blog/spot-fake-qr-code-quishing/. Free checker: https://qrcodescankit.com/tools/qr-code-scam-checker/ Q: What does QR stand for? A: Quick Response. The QR code was invented in 1994 by Denso Wave in Japan to track car parts. Q: What is a QR code used for? A: To pass information to a phone in one scan: a website link, Wi-Fi details, a contact card, a menu, a ticket or boarding pass, a payment request or a location. Q: Is a QR code AI? A: No. A QR code is a printed pattern of black and white squares that stores text, usually a link. Any camera with a decoder reads it; no AI is involved. Q: How do I make a QR code? A: Use a QR code generator: type the link or text, then save or print the code. QR Code Scan Kit has a built-in generator for links, text, Wi-Fi, contacts, email, phone and social profiles. Codes made in the app are static, so they never expire. Q: Can QR codes be free? A: Yes. A static QR code (the information is inside the code) costs nothing to make and works forever. Only dynamic codes, which point at a redirect service, depend on that service staying active. Q: Where is my own QR code on my phone? A: A phone has no single QR code of its own. Apps show your personal code in their settings (for example WhatsApp), and Wi-Fi can be shared as a code: on iPhone in the Passwords app (iOS 18 or later), on Android in the Wi-Fi settings under Share. Q: Can I copy a QR code? A: Yes. Save or screenshot the image to share the code itself, or scan it and copy the text or link it contains. Codes made in QR Code Scan Kit can be saved and shared. Q: What is the difference between a QR code and a barcode? A: A barcode (like UPC or EAN) is a row of lines that stores a short number, read in one direction. A QR code is a square grid that stores much more, such as a full web address or Wi-Fi details, and can be read from any angle. Guide: https://qrcodescankit.com/blog/upc-vs-ean/ Q: What is a barcode, in simple words? A: A pattern of lines that stands for a number. Scanning it gives the product number, and a shop's or a public database's records turn that number into a name and price. Q: How do I scan a barcode? A: Use a barcode scanner app such as QR Code Scan Kit or Google Lens and point the camera at the lines. On a computer, the free online barcode scanner reads one from a webcam or photo: https://qrcodescankit.com/tools/barcode-scanner-online/ Q: What can a barcode tell you? A: The product number (GTIN). The first digits show which national GS1 office issued the number, not where the product was made. Names, ingredients and nutrition come from databases such as Open Food Facts. Free lookup: https://qrcodescankit.com/tools/barcode-country-lookup/ Q: How do I get a barcode for my product? A: For shops and online marketplaces, get official product numbers (GTINs) from GS1, the standards body, then print them as UPC or EAN barcodes. Free barcode images are fine for your own stock and labels, but retailers usually require GS1 numbers. Q: Can I scan many barcodes into a spreadsheet? A: Yes. QR Code Scan Kit's batch scan reads code after code and counts repeats, then exports a CSV for Excel, Numbers or Google Sheets.

Each feature below has its own short page: what it does, how to use it, and what it doesn't do. - [A QR code reader for iPhone that tells you what a code is](https://qrcodescankit.com/features/qr-code-scanner/): Open QR Code Scan Kit and point the camera at a QR code: it reads it by itself and shows what the code is (a website, Wi-Fi network, contact, event or payment) with one button for the next step. Codes in screenshots and photos work too, and scanning happens on your phone, so it works offline. - [A barcode scanner for every barcode you meet](https://qrcodescankit.com/features/barcode-scanner/): QR Code Scan Kit is also a barcode scanner: it reads product barcodes (EAN-13, EAN-8, UPC-A, UPC-E), ISBN on books, shipping and stock codes (Code 128, ITF-14) and 2D codes such as Data Matrix, PDF417 and Aztec. For product barcodes it checks the check digit and shows the product when it is listed. - [Check where a QR code goes before you open it](https://qrcodescankit.com/features/link-check/): Scanning a QR code is safe; opening the link is where scams happen. QR Code Scan Kit shows the full web address before anything opens and warns you about the common tricks: look-alike letters, hidden redirects, the @ trick, bare IP addresses and links that download an app file. The check runs on your phone. - [Join Wi-Fi from a QR code in one tap](https://qrcodescankit.com/features/wifi-qr-code/): Scan the Wi-Fi QR code on a café wall or a friend's fridge and tap Join network: QR Code Scan Kit reads the network name and password from the code and your iPhone joins, so you never type the password. You can also make a Wi-Fi code for your own guests. - [Batch scan barcodes and export them to a spreadsheet](https://qrcodescankit.com/features/batch-scan/): Batch scan keeps the camera running and adds every new code to a list; scanning the same product again counts one more, so you can count stock on a shelf. Review the list, change counts, save it to a folder and export a CSV file that opens in Excel, Numbers or Google Sheets. - [Make QR codes that never expire](https://qrcodescankit.com/features/qr-code-generator/): The Create tab in QR Code Scan Kit makes QR codes for links, text, Wi-Fi, contacts, email, phone, SMS, events and places, social codes for WhatsApp, Instagram, YouTube, Facebook, X, LinkedIn and Telegram, and shop barcodes. They are static codes: the information is inside the code, so they never expire and keep working even if you delete the app. - [Find any code you scanned, any time](https://qrcodescankit.com/features/history-folders/): The iPhone Camera forgets a QR code as soon as you look away. QR Code Scan Kit saves every scan in a history on your phone, grouped by day, with search, stars and folders, so the Wi-Fi password or the event link is still there next week. - [Scan a food barcode to see what's inside](https://qrcodescankit.com/features/product-lookup/): Scan the barcode on a food product and QR Code Scan Kit shows its name and photo, a health grade from A to E, sugar, fat and salt levels, how processed it is and its additives. The data comes from Open Food Facts, a free public database, and it's a guide to compare products, not medical advice. ## Guides - [How to Scan a QR Code on iPhone: 3 Easy Ways](https://qrcodescankit.com/blog/how-to-scan-qr-code-iphone/): Open the Camera app, point it at the QR code and tap the yellow link that appears. You don't need an app for that. If nothing shows up, turn on Settings › Camera › Scan QR Codes, or use the Scan Code control in Control Center. - [QR Code Not Working on iPhone? 10 Fixes That Work](https://qrcodescankit.com/blog/qr-code-not-working-iphone/): First check Settings › Camera › Scan QR Codes is on. Then wipe the lens, add light, and move the phone further back until the whole code is sharp. If the code is printed too small, damaged or has no blank border, no phone will read it reliably: the code needs fixing, not your iPhone. - [How to Scan Barcodes Into Excel or Google Sheets](https://qrcodescankit.com/blog/scan-barcodes-into-spreadsheet/): A USB or Bluetooth barcode scanner types the number into whichever cell is selected, like a keyboard. A phone app can scan a batch and export a CSV file that opens in Excel, Google Sheets or Numbers. Either way, set the barcode column to Text first, or the spreadsheet drops leading zeros and turns long numbers into 6.15E+12. - [How to Scan a QR Code From a Screenshot or Photo](https://qrcodescankit.com/blog/scan-qr-code-from-screenshot/): On iPhone, open the screenshot in Photos and tap the Live Text button, then the link. On Android, open it in Google Photos and tap Lens. On a computer, drop the image into an online QR scanner.

On Android, open Wi-Fi settings, tap your network and tap Share. Guests point their camera at the code and tap Join. For a sign on the wall, make a Wi-Fi QR code once and print it. - [How to Spot a Fake QR Code (Quishing) Before You Scan](https://qrcodescankit.com/blog/spot-fake-qr-code-quishing/): Scanning a QR code is harmless; opening the link is where the risk is. Be suspicious of stickers on top of codes, codes in unexpected emails or texts, and any code that asks you to log in or pay. Read the full web address before you open it, and when money is involved, type the official address yourself instead. - [UPC vs EAN: What's the Difference Between the Barcodes?](https://qrcodescankit.com/blog/upc-vs-ean/): UPC-A is a 12-digit product barcode used mainly in the US and Canada. EAN-13 is the 13-digit version used almost everywhere else. Both are GTINs from the same GS1 system: put a 0 in front of a UPC-A and you have the matching EAN-13. Shops in North America have scanned EAN-13 since 2005, so either works for retail. ## Free tools (run in the browser, nothing uploaded) - [Barcode country lookup](https://qrcodescankit.com/tools/barcode-country-lookup/): Type a barcode or its first 3 digits to see which GS1 country office issued it, with the full prefix table.
