Create QR codes for networking easily - whether it is for your business, social media, or website. Designed with privacy in mind and working completely offline. Have all your business and social cards, right on your phone, always by your side and simply beautiful. VCARD QR CODE - SHARE YOUR CONTACT INFORMATION COMPLETELY OFFLINE Select your contact, choose which fields to include in your card and its QR code - and you’re done. Whenever you make changes to your contact, they are automatically reflected in DejaView as well. So, forget about forgetting to update your business cards.* *Auto-Updating requires permission to access contacts and is optional. You can use DejaView without Auto-Updating and update your card manually instead. URL CARD Create a QR code from any link you like. Whether it is instant messaging, your homepage, profile on a social networking platform or landing page. Just paste the URL and you’re good to go. SUPPORT FOR OVER THIRTY POPULAR PLATFORMS When you’re using a link for one of the supported platforms, the app automatically offers a matching card design with brand color and icon. INDIVIDUALIZE YOUR CARD Create a stunning card easily: select a picture and choose your favorite background color, gradient color, and text color. This only affects your card’s design – the selected picture won't be part of the QR code due to technical limitations. AUTO-COLOR You don’t want to worry about color schemes? No problem - we got you covered. With auto-color DejaView automatically adds a beautiful gradient to your card based on your selected background color and chooses the appropriate text color according to WCAG AA contrast-ratio. WIDGETS Choose from various Home Screen Widget types (just text, picture and/or QR code) and sizes (small, medium, large) or add a widget to your Lock Screen. STANDBY MODE With StandBy you can add QR code, picture or just text widgets to your screen. HOME SCREEN QUICK ACTIONS Directly access up to four cards right from the app icon. PRIVACY BY DESIGN No dependencies, no servers, no internet connection, no registration, no user account, no tracking, no nothing. UNLOCK QR CODES DejaView is try-before-you-buy. You can create various cards, make use of widgets and all other features. This enables you to check, if the app fits your needs, is appealing and working within your personal workflow - no account or registration required. DejaView is for you? Simply get DejaView Pro to unlock QR codes. It’s a one-time purchase and comes with a lifetime license. MORE FEATURES Match your Home Screen by choosing from three different app icons Fine-tune display settings based on your needs Got a lot of cards? Find the card you’re looking for easily with search Support for English, German, Spanish, French, Italian and Portuguese ABOUT DEJAVIEW We think, paper business cards have reached the end of their lives. In most cases you always print way too much and when your job title or phone number changes, you still have left plenty of them. So, what about NFC cards made of plastic or metal? While this solution may be more versatile and easier to update, you still have a physical card, adding bulk to your wallet. And: you are depending on a service, hosted by the provider of your NFC card. Which means no offline functionality and once the company stops offering their service, your plastic/metal card is simply useless. For this reason, DejaView works without any external dependencies or servers involved. When you choose to create a vCard QR code, your contact information is included in the QR code itself – eliminating the need for an internet connection when scanning the code.
