[00:00:00]Why did the magnetic stripe lose to that tiny gold chip?

[00:00:04]Not because the chip is faster. It isn't.

[00:00:07]A magnetic stripe is essentially a cassette tape. Tiny magnetic particles encode your card number.

[00:00:14]Anyone with a stripe reader can copy it perfectly onto a blank card.

[00:00:18]The chip changed that. The chip is a tiny computer.

[00:00:22]When you insert it, the terminal powers it on and they hold a brief cryptographic conversation. The chip proves it knows a secret without revealing it. Every transaction generates a unique signed code. Even if someone records the entire conversation, they can't reuse it.

[00:00:41]The stripe could be copied. The chip can't. Follow for one curious thing every day.
