The AirCard Pro is a credit-card-shaped Bluetooth tracker that slips into a wallet or attaches to keys. It is the first card tracker with a wirelessly charged battery, and it works with either Apple Find My or Google Find Hub depending on the version. A 20mm buzzer makes it easy to hear in a pocket, and it sends a left-behind alert when you walk away. It suits wallet and bag carriers who want a slim tracker without a coin-cell swap. Against AirTag-style rivals it is thinner and rechargeable, but the left-behind alert only works on the Apple version.

Rated 4.5 out of 5 from 615 ratings. Owners like the slim card shape, the rechargeable battery and the loud beep; complaints center on the network split between versions and the missing left-behind alert on Android.
AirCard Pro is a card-sized Bluetooth tracker that works with either Android or Apple. The white versions use the Android Find Hub network. The black version works only with Apple's network. A low-energy Bluetooth signal detects devices within that network to triangulate and locate keys or a wallet.
A 20 mm (0.8 in) buzzer lets you make the card beep from the Find My app, or by asking Google or Siri. The sound can be heard in nearly any environmental condition and in narrow spaces such as wallet pockets. When the card is left behind, the Apple Find My app sends an immediate notification. This reminder is not yet available in the Google Find Hub app.
The card has an ultra-flat wireless-charging lithium battery that provides 12 months of battery life. To recharge, place it on a wireless charger for around 1 hour 30 minutes. A QR code opens Sherr.it, where you can create a Digital ID with contact info, social media links and a short bio. In QR Lost Mode, you set a custom message and show only the contact info you choose. Anyone who scans the code with the "Scan if found" prompt can contact you.
