Maybe consider getting one of those zippered folio type wallets that you keep at home or in your car (one stable location) to be the master card storage place and get a wallet case for your phone for the most important common cards you need to keep on your person at all times. Get that AirTag and keep it in the folio, then use the wallet case for your phone as you go about everyday which houses your iphone which you can track in itself because its an iPhone or whatever
