> EDIT: I see the general problem of origination fraud. But that can be mitigated by imposing limits and requiring extra levels of authentication for bigger payments.

Which are exactly the kinds of things credit cards do, but it can't be perfect so they still suffer losses, so they still have to charge a percentage.

(Of course a lot of the percentage can go to rewards programs, so we're talking about the percentage once those are accounted for.)

In the US you can take money from a credit card by just using the that’s plainly written on it. That’s not what I would call making an effort at origination fraud prevention.

Believe it or not, they make a huge effort at fraud prevention. Because it takes away from their profits.

However there are both historical and convenience reasons at play here. It was a big transition to move to chips, for example.

So your assertion that they're not making an effort at fraud prevention is just completely untrue.

Hell, you can take money from a bank account by just using what's written on a cheque...
