PINGTAG vs Unravel

The emergency contact QR tags for your car and personal items

A PingTag is a printable tag with a QR code that you attach to your car and your personal items, so that people can scan it to message you in case of an emergency, without revealing your phone numbers to each other.

Each PingTag you create and attach to an object acts like a dedicated phone number that privately relays messages to your phone and/or email, while keeping your actual phone number private.
