Special gadgets attached to a keychain, bag or wallet flash when one of these items has been forgotten at home. If some object is not accidentally taken by their owner on the road, small round devices blink and make different sounds.
In the case of a smartphone, this device can also help. Just download the special application and install it. Having installed the Trakkies program, the user begins to receive special instructions for the search.
These devices react to movements and interact with each other - when the owner of the phone, keys or wallet leaves, forgetting something, the electronic circles are activated.
“Trakkies communicate with each other regarding location and traffic - the system starts working when you are going. If you forget something, the system feels that the object is not in motion or located far from everyone else,” says the head of the operation service of the Dutch company Trakkies.
