@alice@lgbtqia.space @deviantollam@defcon.social I think the concern I have with the magstripe existing is that a chip reader gas pump can still be hiding a magnetic skimmer.
I live in the third most populous city in North Carolina and many gas stations are still not using chip readers. Including the ones operated by the local grocery monopoly.
I should see of my credit onion supports purchase limits. I can't think of anything that costs $1800 that I would use a card instead of ACH for. Which of course has its own problems...

@wbud@tech.lgbt @alice@lgbtqia.space @deviantollam@defcon.social On the payment processor side, the type of card data capture is part of the transaction. The technical capability exists at the payment network level to say, for example, a typed-numbers transaction is limited to $10, a magstripe transaction is limited to $20 (the stripe has more data than just the card numbers), a tap is limited to $50, a chip-without-PIN is limited to $100, and a chip-with-PIN has no limit. Whether the bank actually does anything with that technical capability or not is up to the bank. Worth asking them, though.
