The (completely legitimate) anti-tracking measures built into AirTags means that they're not really viable for tracking things that have been stolen. Recent iOS devices will alert you fairly rapidly if you've got an AirTag that isn't registered nearby when the owner of that AirTag also isn't nearby. That means that if someone steals your wallet with an AirTag in it they're going to get alerted to the fact it's trackable within 30 minutes or so, and given instructions on how to disable the tag. Scanning the tag with any NFC capable device will also allow disabling it - I could definitely see professional pickpockets waving a phone over any wallets they take to kill tracking as soon as they can.
