The Swissdigital Finder Keychain is designed to discourage unwanted tracking. If someone else's SDD Finder / SDD backpack / SDD handbag / SDD luggage finds its way into your personal items, your iPhone will give you a notice that a Finder is traveling with you and send you an alert on your iPhone. After a while the Finder will play a sound. This notification is warning you that there is an SDD Finder near you. This notification does not give you permission to go into someone else's items such as bags, backpacks, handbags, and luggage to disable the SDD Finding system or other illegal actions.
