Years ago when i ordered from a site they had a system where they would charge you slightly less than the price on the order, but you had to quickly verify the last 2 digits. Ie a $100 item and they would charge you 99.97, and auto cancel the order if you cant provide the actual cost (from your internet banking). Since credit card charges appear instantly this was pretty simple.

I'm surprised I've never seen such a system since, it seems very effective against stolen cards.

I'm not surprised; a system like that increases friction and would turn some non-zero customers away.

My bank doesn't (easily) let me see the transaction amount in the original currency. It always shows the amount after conversion, I'm not even sure if there's a way to see what the original amount actually was.

They do this to authenticate payment methods in for example PayPal
