That’s the point unfortunately. Wearables are functionally identical to implants as far as design, and they’re allowed. It’s just the implant form factor that they explicitly do not allow because of fear or PR backlash. Mastercard and Visa are global companies though. You can certainly try and negotiate with them, or approach another issuer like American Express or Discover, but ultimately they’re all operating under the EMVCo spec. It’s gatekeeping in the most extreme sense of the word I’ve ever witnessed, because ultimately their decisions are the global economy.
Legitimately is the only way you’re going to get tokenization working, which means the implant “won’t expire”. Otherwise everything illegitimate is a conversion, and all of those expire.
