Project vCard is a global initiative to create a network of linked vCards. Our service is to take the hassle out of managing change in your address books by simplifying the process. Changes to phone numbers, emails and addresses happen all the time. Whether it’s your own contact information or others, you need to get them updated eventually. Most of us often put that task aside for a moment and by the time we remember, our address book is messy, outdated, and we get overwhelmed. Changes to your contact information can happen when: • Changing jobs • Moving to another city/country • Starting a new life • Adding/deleting phone lines or emails • Involving your privacy • Etc. IT’S THAT SIMPLE! Through Project vCard, all you need to do is manage your own vCards. Then decide which vCard to share and link with other users. Our app does the rest. AUTOMATIC UPDATES With Project vCard, your address book is automatically updated over time. And whenever you change your own contact details, you will not need to send any emails or messages to each of your contacts around the world. FEATURES: Conveniently customise each vCard. You can choose to provide different contact details for different purposes or occasions. Easily link with other Project vCard users by using QR codes or by searching for their vCard IDs. Linked vCards show up in your device’s address book and automatically update any changes. As we continue to improve Project vCard, additional new features will be implemented very soon.
