Contact Hi gives you complete control over how much or how little of your contact information you want to share publicly.
• Simply select your personal Contact card from your devices "Contacts" list
• Tap the Settings icon to control how much or how little info from your Contacts card you want to share. There might not be a need to share your birthday, or other details you wish to keep private.
• A scannable QR code is then created. Every time you change a contact, or modify your Settings, a new QR code is generated.
* You can always see at a glance the info you have embedded in the QR code by tapping the "Info" icon above it.
• Select a picture from your Photos library to be displayed behind the QR code image. It is best to select a picture that does not contain a face, as this can sometimes confuse the iPhone scanner.
• Save the new combined image (QR Code and your backing image) to your Photos with one click of the camera icon.
• You can now go Settings->Wallpaper and set this new image to be your Lock Screen image. Now anyone can quickly scan your lock screen to add you as a contact!
• Great for conventions, business meetings, or group social events. As long as your Lock screen is visible, you dont need to do anything else to share your contact information with others!
