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.

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.

ReceptionRating · Positive reviews · Number of ratings

DejaView holds the better App Store score, 5.0 against 1.0. That said, the two scores are not equally well evidenced: DejaView has 5 ratings behind it against 1, so its average is the more settled of the two. Written reviews complicate that: 63% of Qr Code Scan + Generate's written reviews are positive against 0% of DejaView's, so the app with the better star average is not the one people write more warmly about.

UpkeepUpdate frequency

Qr Code Scan + Generate ships an update monthly, DejaView every 3 months. The most recent releases landed on September 23, 2026 and September 27, 2026 respectively.
