Nomad released a card for tracking your wallet
This is an ultra-thin card, just 2mm thick, with Locator support, which can be tracked using an iPhone. It is added to your Find Me network so you always know where your wallet is.
Inside, there’s a battery with wireless charging, and a single charge lasts for five months of use. It also has a speaker for sound alerts and water resistance up to the IPX7 standard.
The device costs $40, but the first batch has already sold out.
