@ww @ity ah, the qr codes thing is cool, and something i didn't actually know about. still tethers me to my phone or similar device though.

how i had imagined a theoretical 'crypto card' working was very similar to how payment cards work now
a transaction is generated by the vendor, signed with the card and pin, sent to the authorizer, authorizer/wallet holder transmits the payment, the payment shows up at the vendor, transaction complete
it enables one to be their own payment processor/authorizer, assuming they can program their server details into the card, also allowing for cool stuff like, say, dual authorization, a sort of y/n prompt showing on a device for any transactions over a certain amount

it still doesn't solve so many blocking problems, of note, incompatible currencies, the 51% rule and accessibility to non technical folks... seems like introducing a whole hell of a lot of pain for such tiny benefit
