Yes. If you’re in the US, the only current option is the Purewrist conversion
Basically, you buy a Purewrist GO bracelet. The actual payment piece can be removed from the bracelet, and you then send that to Amal (after buying the Conversion Service). He then converts it into a flex device that can be implanted. All of the details are on that page.
However, Purewrist devices only last ~3 years before they expire. They essentially act as a prepaid debit card, you top them off from another account. After it expires, it will be essentially useless.
If you happen to be in the EU, there’s the Walletmor implant, which currently lasts 5 years before expiring.
The VivoKey Apex Flex is coming SOON™. It can in theory do payment implants, it has everything needed technologically, however, either Mastercard or Visa have to authorize it, which hasn’t happened yet. It’s unknown if they ever will, but AFAIK, talks are still ongoing. If they ever do, the “switch” can be flipped, and they can start making payments.
