    I think mDL is going to be a pretty big deal in some industries (e.g. banking). Apple announced an ecosystem around this at WWDC25. Very soon we are going to be in a world where you walk into a bank to open/maintain an account and the following occurs:

    1. The bank emails/SMSes the customer a link

    2. The customer takes out their iPhone, opens whatever email/messaging software & taps the link

    3. The link takes the customer to a specially crafted page owned by the bank that triggers a native OS process for opening Apple Wallet and gathering requested ID details with consent.

    <a href="https:&#x2F;&#x2F;developer.apple.com&#x2F;videos&#x2F;play&#x2F;wwdc2025&#x2F;232" rel="nofollow">https:&#x2F;&#x2F;developer.apple.com&#x2F;videos&#x2F;play&#x2F;wwdc2025&#x2F;232 <a href="https:&#x2F;&#x2F;www.w3.org&#x2F;TR&#x2F;digital-credentials" rel="nofollow">https:&#x2F;&#x2F;www.w3.org&#x2F;TR&#x2F;digital-credentials

    This is potentially a superior arrangement because it could eventually establish a strong cryptographic chain of trust all the way to the issuer (e.g. the State of Alabama). Right now there are some gaps in that chain but I see no reason they couldn&#x27;t be closed over time.

      My elderly parents and some of my technology illiterate coworkers are going to hate that with a passion.

        Add in anyone on the opposite end of the tech spectrum too, especially those working in security.
