Yea, but those are different services that utilize the history of your transactions. What reason does an online retailer have to access that level of detail? Shouldn't they simply be able to accept the information on the credit card for the sale?

They can reduce their risk by doing this. For online retailer there is always risks in accepting card payments. (Not saying this is a good idea, just trying to find reasons).

Whose risk is reduced? The retailer or the bank? Certainly not the cardholder.

The retailer and only the retailer.

It probably reduces fraud chargebacks to nearly 0.
