Bluetooth tracker company Tile has a new product: the $30 Tile Slim, a tracker about as thick as two credit cards that fits easily inside your wallet.

While the original Tile tracker is sticking around, Tile boasts that the Slim is “the world’s thinnest Bluetooth tracker designed specifically for wallets.” Like the original Tile, the Silm was designed to help you keep track of items you often lose (or can’t afford to lose) — like your wallet, blazer, or laptop (via an adhesive).

Fresh off an $18 million round, Tile is also beginning to sell its tracking tech to third-party hardware companies, starting with scooter maker EcoReco, PowerPack maker Nomad, and “smart wallet” maker Zillion.

Every tracker Tile makes is part of a larger user network that enables the company to locate lost items beyond the physical range of Bluetooth — say, if you lost your keys at a cafe, someone else’s Tile could reveal their location in Tile’s app.

“Opening our platform to allow other companies to build Tile’s smart location technology into their products will expand our network quickly,” said Tile CEO Mike Farley, explaining that this “creates value for our community of partners and consumers by finding items even faster.”
