    As a sidenote here I have a different issue where handing people your CC info is basically handing out the private keys to your bank account to a third party.

    I’d really like it if a credit card would use a public key system where you can verify that I have the funds and that the payment originates from the payment provider instead of getting my full CC details. I don’t really see why it’s necessary for a business to know who I am instead of just getting a green light from Mastercard or Visa to make the payment.

      That’s why I love virtual card systems like MB NET. You just generate a random virtual card for every purchase (or a recurring one for each subscription vendor, for example) and move on. Your bank still knows what you’re doing, of course, but vendors can’t correlate anything. Preventing your bank from knowing where you’re spending your money is much harder, for very practical reasons: fraud detection. The only real way is to use a secure crypto coin like Monero, but very few places accept it and you still have to deal with volatility.

      Aren’t cellphone NFC payment essentially a long-form version of this? As far as the machine is concerned they’re getting your CC info, but Google/Samsung/Apple Pay are acting as a middleman and your actual credit card information is never actually shared.

        As far as I know, modern cards don’t just send your CC info to terminals, they do some form of a cryptographic handshake (probably a pubkey signature or similar) which gets confirmed by your bank. I believe Caveman was talking more about online shopping, where you have to enter your card number, expiration date, CVC and often your name too.

        Yeah, it has it’s perks but my NFC stops working on a regular basis. Also I don’t like having my payments go through a spyware conglomerate.

    Buy a prepaid visa with cash. Not technically a credit card, but it may be what you’re looking for.

      Most major American sites no longer accept these and they have become finnicky including locking the card so you have to call the call center to reopen the lock. This is due to curb laundering. Walmart in person works. Gas stations work. Used to work everywhere now, not much.

      Probably the closest thing you can get to in terms of a “privacy” credit card. Everything about a credit card is tied to you by their very nature. So it depends on what or who you want privacy from.

      Someone else mentioned privacy.com which I also use - it’s good if you want to hide your transaction from the credit card company, or if you want to hide your identity from the merchant. But Privacy.com is more like a virtual debit card that connects to your bank account. Privacy.com still knows who you are.

        Your identity, most of the time, is not revealed to the merchant. The payments online and through a credit-card machine are processed through a 3rd party. The seller doesn’t get your info, only money on their bank account.

    The whole point is that everything is in an official ledger, that can be argued over in front of a judge.

    Best you can do is say you don’t consent for your data to be sold. Find a smaller bank or a credit union where they have to give a shit about their customers.

      Doesn’t your credit card provider still get all your data?

      E.g. doesn’t visa/mastercard know about every transaction? They charge fees and they have a fraud prevention systems. So, I think, they do, right?

    All the banks here use an inter-banking system that allows for virtual credit cards, they can be use once or periodic, always single-merchant and always capped.

      Me in yurop, using a debit MasterCard, never needed a credit score. Who has my data, what are they doing with it, and how do I burn down their server?

      (The answer, kids, is Stripe. Give it some years, it will be lit)

        mastercard sends your transaction data live to banks. They sell your data to third parties for marketing, profiling and the likes. Credit score is the least of your problems.

        I know because I developed a system, in a major European bank, enriching their transaction data with mastercard data for live, predatory marketing.

    That’s a great question if also been wondering for some time now. Obviously I can pay in cash, and only in XMR, no problems there. But when my cash runs out, how do I get the cash out of my bank account privately? I can’t go to an ATM with XMR or Google/Apple pay. Also then they know information I don’t want them to have. If I use my bank card the bank still knows where I am and how much cash I spent in a specific time frame. Anyone hast ideas on how to withdraw cash private?

      There’s no real way to do it. Unless you know someone who can trade you XMR<->cash and you somehow convince your employer to (break laws and) pay you in those forms, you can’t avoid it. At some point, you’ll have to get money on a real bank account, which requires real information to open.

        Thanks for the answer, best option then is probably to always use the same ATM where I live and at least be a bit less traceable that way. But yeah this system sucks…

          Yeah withdraw cash from an ATM and use it. The system sucks, but it’s not trivial to change for a myriad of reasons.

    I don’t know what you’re referring to exactly, but for me, I like using normal credit cards through Apple Pay because the recipient doesn’t get your actual credit card number and a different number is used each time

      The credit card company and everybody buying that data from them still does though, probably, which for me is the bigger concern.

        Well, so does your credit card company and they sell that info to the same companies Apple does, so nothing is really lost but a little is gained.

        Really, there’s not much private about credit cards at all, so idk what’s with this thread…

      Google Wallet, formally Google Pay, formally GPay, formally Android Pay, formally Google Wallet, formally Android Wallet, does the same thing.

      Switching phones and returning something was such a pain since it generated an entirely new number.
