Digital wallets and the “only Apple Pay does this” mythology
I hope what you take away from this post is that while Apple Pay is a great way to pay for things and that Apple did a great job mainstreaming digital wallets like this, what they do is not unique in the industry. DPANs are great for making it harder to track one person's purchases across multiple merchants and they make customers less at risk in the event of a data breach of payment card info.

The gist of the article is that all the things Apple claims are unique about Apple Pay are really not unique at all, and quite a few things Apple touts are just flat-out lies, such as merchants being unable to know what you buy or people being unable to track you when you use Apple Pay. Other digital wallets, from Google, Samsung, and others, work in the exact same way Apple Pay does, and even banks and similar companies implement their payment systems the way Apple Pay does.
It's a case study in how Apple's marketing and PR bloggers manage to perpetuate a myth solely because so many people just assume it must be true. Apple wouldn't lie, right?
