Whenever your contact details are changed, your entry in your recipients' address book is updated.
Contrary to contact QR codes, ScreenTag supports almost every character set reading left-to-right.
If a recipent does not have a QR code reading app in his phone, you may text her/him a link to your contact info file instead.
Your recipents do not need to download apps to manage your contact info. ScreenTags are stored in their primary address book.
Since your ScreenTag is stored in cloud servers hosted by Microsoft, it follows you anywhere you go, 24 hours a day.
Your ScreenTag QR codes are optimised for easy scanning recognition by any QR code reading app.
Unlike with printed business cards, you don't have to update your screen image whenever your contact details are changed.
You only have to re-download your ScreenTag image from your Google Drive, iCloud Drive or OneDrive.
Unlike your printed business cards, your ScreenTag may be used without any limitations of any kind.
