Does it though? The people in this thread are like "just use a card". Well I've done that for years and had my card skimmed, lost, and stolen over the years. The cost wasn't trivial either. The credit card company knocked it off my balance but also lost on sales when I didn't have my card while they issued me a new one. It cost the credit card company actual money in both lost sales and in dealing with the fraudulent transactions.

Now if I was allowed to use my rooted Android phone during those years? It would have been locked down tighter than the vast majority of Windows boxes.

People forget that one of the value-adds of credit cards in the first place is that suddenly you didn't have to walk around with a big wad of cash. Credit cards gave you that extra level of security. Even if someone stole it, it's useless to them as soon as you make a phone call to the CC company. We can verify a transaction with a yubikey-like secret store on your device that never shares the private key with the operating system and which generates a virtual credit card on the fly. That's literally how Apple Pay and Google Pay already work. So whether a device is rooted or whatever literally doesn't matter.

I definitely use one of those wallets. They're quite convenient too.
