The Marengo tag is a very versatile tag:

• it allows you to add all sorts of information about your pet, such as its name, age, medication, etc.
• it allows you to add multiple names and phone numbers of emergency contacts
• if your dog is lost and found by a kind person, they can scan the QR code on the back of the tag, which will send a location signal to your phone.

The Marengo tag therefore functions like a regular tag, but it contains more useful information and acts as a passive GPS.
