Not at all, sounds like you to need a little review yourself [1]. At no point in my comment did I support mag stripe, just simply explain why it's still in widespread use. If you ever have worked in the finance industry you would understand that. Nobody is arguing that it should stay, but it's important to understand WHY they are still around. Just because it's the major standard doesn't make a good one.

Ignorant? Really? I expect more constructive comments here on HN instead of running around and calling people's comments "ignorant". Perhaps you need to review the HN Guidelines [2]. Specifically: 'When disagreeing, please reply to the argument instead of calling names. E.g. "That is idiotic; 1 + 1 is 2, not 3" can be shortened to "1 + 1 is 2, not 3."'

Alas, it will not be happening based on the latest abuse of downvotes on HN.

Being number one out of two means you're the majority. Being number one out of over a hundred does not. You claimed that because the US is number one (with 15.6% of world GDP), the other >100 countries (with 84.4% of world GDP) have "zero weight".

"The rest of the world is irrelevant" doesn't go over well and gets downvoted because it's obviously false.

Is GDP the relevant metric to assess this?

On credit/debit card transaction volume North America represents 40+% of global market.

Right, except it's not in widespread use, it's only in use the USA.

The USA does have a huge economy. However in this matter it does not dictate the standard, and there are more people doing more card transactions outside the US, with non-stripe technologies, than there are in the US doing them with.
