I didn't attempt it, but it should function as expected. Will try next time I use it. This is because without using it, you have to pinpoint the precise sweet spot near the iPhone's camera for it to work; otherwise, it won't function correctly.
As for the wallet, if you're considering placing the card in the card holder, I believe it won't fit with the sleeve. This is because it's approximately 1cm wider than the card, and most card holders are designed to be quite snug, typically accommodating just the cards. Cards with covers or sleeves like this one are often challenging to fit.
In the case of Bisq, I need to double-check, but my computer was at 100% for a considerable period, and the synchronization process already completed. I'll need to attempt it again to be sure.
