Because it is cryptographic authorization that allows to make payment, not just card details. You can read it, but card number is not enough to make payment in card-present mode.
Whole point of EMV is that card cannot be cloned, as is trivially done with magnetic stripe card. You can do relay attacks, but this is so cumbersome, with PIN required at higher amounts, that I doubt anyone actually does it in practice.
- tjoff 6y agoDoesn't matter? I'll just use the details that I got on the internet instead.
- garaetjjte 6y agoCard not present transactions are ridiculously insecure, but that's totally different matter. That is complaining that EMV doesn't protect against transactions not made by EMV.. of course it doesn't. And these can be chargebacked easily anyway.
