This is only for magstripe-emulation contactless, which is very regrettably a thing, thanks United States! The civilised world uses true EMV contactless.
Edit: Huh, even the US will be forced to use EMV contactless soon, apparently. Makes sense that Visa and Mastercard wouldn't want to support that massive fraud risk for long.
- _bxg1 7y agoFrom a quick search, it sounds like "EMV contactless" means the NFC circuit follows the same procedure as "the chip" instead of the same procedure as the magstripe? If so, that would indeed solve the problem
- TazeTSchnitzel 7y agoYes, exactly.
