The financial system in the US is so out of date. Not only are the chip-less cards obsolete, cards in general are very dated. But it goes way beyond that. In fact the entire system is full of patchwork legacy nonsense. The starting point is this: imagine you are creating a new digital banking system from scratch. How can you ensure: A) that people can make secure payments in person and online without having to give out secrets such as debit card numbers and B) the integrity of the entire system, such as preventing banks from finding creative ways to add funds to their friends' accounts? Its worth learning about digital signatures and block chains. And compare the current system to that.
