Looks like from my initial reading that credit cards generally cannot be made wearable or implantable, outside of the payment conversion chip that doesn’t work with cards that are EMV and contactless (as they are here in Australia).
One bank here, Bendigo Bank, offers the Halo payment ring but the rest (we have four major banks) offer Google and Apple Pay integration on watches, phones, etc.
I’d love to get credit card payments on a ring for one of the major banks. Less so an implantable because of expiry and cards being rolled.
Anyway, I thought I’d ask this again in case things had changed or my research was wrong.
In the meantime I intend to get a Halo and wire money to it as needed. My phone will be in a super tough case (I obliterate phones) and none of these seem to work with NFC.
