What it is

The Nokia Treasure Tag WS-2 is a compact Bluetooth 4.0 proximity sensor designed to attach to keys, wallets or bags. It pairs with a Windows Phone running the Treasure Tag app to alert you when a tagged item moves out of range. Up to four tags can be managed simultaneously from one handset.

Deciding specification

The only wireless link is Bluetooth 4.0 with NFC tagging for the initial pairing handshake. There is no ultra-wideband, GPS or cellular radio inside the tag, so location updates rely entirely on the phone remembering where the Bluetooth connection was last lost.

Installation and pitfalls

Setup requires downloading the Treasure Tag app from the Windows Phone Store and tapping the tag to the phone to trigger NFC pairing. The replaceable coin cell lasts up to 180 days on standby; a dead battery is the most common reason a tag stops responding, and the app cannot locate a tag that has no power.

Questions about this item

What does the 180‑day standby figure mean when the tag is paired to my phone?

It means the tag can stay connected for up to 180 days on one replaceable coin battery before you need to swap it.

How does Bluetooth 4.0 affect the range and pairing process?

Bluetooth 4.0 provides a low‑energy link that lets the tag alert you when the connection drops and supports pairing up to four tags in the app.

What do I need to attach the tag to a key ring or bag?

The tag has a built‑in loop so you can slip it directly onto a key ring, strap or zipper pull without extra hardware.
