I'm planning on seeing if I can decode data from higher density mediums with the same approach, when I can get my hands on some iron nanoparticles.

I can't claim to spend a ton of time in a huge variety of countries, but in the past year I've been to Iceland, England, Wales, Scotland, Italy, France, and New Zealand, and I can't remember anywhere I had to use the EMV chip in my credit cards except places like parking garages that didn't have the physical facility for a mag stripe swipe. Every retailer terminal could read a magstripe. More annoyingly, whether I sw…
You're a US resident with a US card? As a UK resident with a UK card it's been a long time since I swiped or signed. I think you must have the "require signature always" bit set on your cards because someone in the issuing chain doesn't trust EMV.
I don't think I have a single card that supports pin.

Archimedes, Da Vinci, I. Newton are just a few that came to mind.
anyone more recent? You see it seems to be that it was a lot easier to know a lot when there was a lot less to know. Now people tend to specialise in one field and know a lot about that field as opposed to knowing quite a bit about a multitude of fields.

The problem of tricking the reader will be solved in the US the same way the rest of the world solved the problem. You stop using magnetic stripes. For the longest time, chip-and-pin readers in most european countries would let you just swipe the magnetic card if you didn't have a chip.. this allowed americans (and whoever else still uses this technology) to be able to shop when they travel. Unfortunately a dispropor…

Here is the campaign that was ran by the largest payment processor letting everyone know the old system was going away. It was heavily advertised all over the country.

Perhaps there is somehow an exception for foreign cards? But this is news to me, and seems like it defeats the entire purpose.
I was very surprised to learn there's no check for Chip and Pin requirements beyond what the magstripe requests. I naively assumed if the card had that feature the terminal could force it to be used. What would happen with the other fields he mentions, like whether or not you can withdraw cash with the card?
IIRC from some resarch I did, a decent card provider will reject a magstripe transaction from a terminal with EMV capability if a card is known to also be EMV capable... At least, it could in theory.
That's how it works for all countries other than the US. In the US EMV capable terminals are not common so transactions in the US are typically permitted no matter if magstripe or EMV. This is why starting with October this year the US are finally making the switch to EMV and once that roll-out is complete, magstripe transactions could (theoretically) be either disabled or severely limited. For instance you might have to confirm a magstripe transaction with a text message.

I got a replacement Amex card (after some fraudulent charges) 4 or 5 months ago, and it had an all new number, not just a few digits. This card also had the embedded chip, so that may be why it had the new number.
The chip is being rolled out to keep up with VISA/Mastercard's deployment of chip. Note however that chip transactions are far slower than proximity or magstripe uses, making it completely redundant except for a malfunctioning magstripe reader. It would have been as much software update to have implemented PIN and would've brought security to the level of ATM cards. The generation and provisioning of card numbers is…
It's also a great deal more difficult to extract the secret information from the chip; I don't know if anyone has done so yet.

A European-issued card would deny use of the magstripe on an EMV reader. This could possibly by overridden by the cashier, but most won't have the authority to do this. (The merchant takes responsibility for fraud in this case.)
