With the app QRContactGuard you can easily share the contact of yourself, colleagues, friends or others from your structured address book. In an intuitive and transparent way, a respective QR code is generated that can be scanned by a second device for transferring the contact details. You have the full control on the content of that QR code by selecting the data you like to transfer. On top of that, you can always display the content that will be transferred as text.
