I had the old tracker card and it was nice. It did exactly what I wanted it tracked my wallet. However, you had to add another app to your phone remember which one it was, navigate its features and hope the battery charged. The new tracker integrates with apples “find my” app which is already used for air tags and other Apple products. Also with the charging cable you know it’s charging and you can monitor the battery life. Another great feature are the magnets in the charger it wont allow you to put it on the wrong way.
