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?

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.

Hook is a system designed to help you start. Place an NFC tag where the action should happen: by the door, in the kitchen, near your desk, or anywhere else in the room. To confirm a task, turn off an alarm, or complete an action, you need to physically walk to the tag and scan it. Why it works Most decisions fail not because of a lack of motivation. The hardest part is getting started. Hook moves action from your thoughts into the real world. Not “getting ready” — taking the first step. Alarm scenario example: The alarm starts You have a few minutes to wake up calmly You need to walk to the tag Scan it You are already out of bed and in motion Hook doesn’t pressure or force you. It helps you stick to your own decisions. Hook is for you if: • It’s hard to wake up in the morning • You constantly procrastinate • Starting work or workouts feels difficult • You are tired of pressing “snooze” • You want to build better habits • You need an external trigger to take action • It’s difficult to maintain routine and discipline Hook can be used in almost any daily scenario: alarms, workouts, studying, work, taking vitamins, nutrition, household routines, sleep schedules, and any situation where starting on time matters. Sometimes all it takes is the first step.
