There are multiple attack vectors. One of them is "why did I just get another charge from that place we visited last June". Another being "oops, we plugged our pin into a skimmer", etc.
Agree that letting Visa/MC/whomever know everything about your transactions is a choice...
Otoh if they pay you 3ish % for it, you might decide you're more than happy to.
- stavros 5y agoI have half a mind to make a debit card that lets you whitelist merchants. You use the same card everywhere, but unless the merchant is in the whitelist, the charge fails. Also, you can set limits and rules. Basically like privacy.com, but why use a new card per merchant?
