Make everyday codes easier to use with QRFast. QRFast brings scanning, code creation, and recent activity together in a focused workspace. Point your camera at a code, pick one from a saved image, or create a new QR code from information you want to share. Whether a code is printed on a package, shown on another screen, saved in a screenshot, or shared with you digitally, QRFast helps you quickly turn it into useful information. Scan from Camera or Photos Use your iPhone camera to recognize QR codes and supported barcodes, or choose an existing image from your photo library. QRFast can handle many common types of encoded information, including website addresses, text, contact details, phone numbers, email addresses, messages, Wi-Fi information, locations, and more. Turn Information Into a QR Code QRFast also works in the other direction. Choose the type of information you want to share and turn it into a scannable QR code. Create QR codes for: • Websites • Plain text • Contact details • Phone numbers • Email • SMS messages • Wi-Fi information • Locations • Social profile links Once created, your QR code is ready to save or share when you need it. Keep Recent Scans Within Reach Previously scanned codes can be kept in your local history, making it easier to return to useful information without scanning it again. Review recent results, copy their contents, reopen links, or remove records you no longer need. Built for Simple, Everyday Use QRFast does not require an account for its core features. QR code recognition is primarily performed on your device. Camera frames and photos selected for code recognition are not uploaded to our servers for scanning, and your scan history is stored locally on your device. From checking a code on a poster to creating a QR code for Wi-Fi or contact information, QRFast keeps the process straightforward from start to finish.
