Proximity sensor in the shape of a small disk, which is placed on the object whose loss is to be avoided.

Easy to use, this accessory enables synchronization with a free application and lets you always know where you left your bag, keys or other important object.

The App installed on an iPhone or Smartphone allows you to emit a sound on the Chipolo to facilitate the location of the object (distance up to 60m), or by pressing the Chipolo button, ring an alarm on your mobile phone. It also alerts if Chipolo moves away from the cell phone.

The Proximity Sensor Card is so slim it fits in any wallet.

If you lose the object, the App shows its last known location on a map; if you report the object as lost, other Chipolo users can help you find it (1 million active users in 2019).
