This accessory works if you live someplace where everything is digital and you don’t really need any physical cards with you. I don’t live in such a magical place. I need my license (like most states we don’t have digital IDs), medical ID (I have a digital one but it’s not accessible from the Lock Screen - what would an EMT do then?), transit card (we don’t have device-based transit payments), credit card (lots of places do NOT have Apple Pay), debit card (when you need cash), plus a little cash. Oops, that‘s 6 things right there, but the Apple Wallet can only hold 3.
And having to remove the wallet + remove all the cards in it to get to the one you need is ridiculous. A conventional wallet doesn’t have this limitation.
