I didn't even feel it happen. Someone took my wallet on the subway during rush hour. I opened my phone, and I could see my wallet moving down the street on the map. I called the police with the exact location. I had my wallet back within two hours. Nothing was touched.

My husband is a good man but he loses his wallet almost every single week. I'd watch him tear the house apart every morning before work — the same panic, every time. I set this up for him in minutes. First time he lost it, he found it in just few seconds. He looked at me like I was magic.

I'd left my passport holder in the back seat of a taxi before even reaching the hotel. I didn't know — until my phone beeped in the lobby. The map showed the taxi was still three streets away. I called the driver. He turned around. Few minutes later, trip saved. I didn't miss a single flight.
