We use the v1 of the Apple MagSafe Wallet but alas it doesn’t have the FindMyPhone feature like the new wallet. We therefore use the Tile wallet tracker. This Shortcut let’s you find exactly where your card wallet is with the Tile wallet tracker and app. Location will show up on the app’s map.
You lose one card space using this but at least you can rest well knowing where your other card is. Be happy being at peace and remember to AutomateOn!
