Have you tried them for privacy purposes? What are your experiences?
Here is mine. I’ve used the Visa prepaid cards. Where I live (USA) you can buy them “anonymously”. Scare quotes because sure, nothing is 100% anonymous now. But you can buy them with cash and activate them without giving a phone #. Not quite as anonymous as cash, but close. It avoids the heavy data trail of a normal CC. And you can use them sometimes where you can’t use cash.
But there’s the prob. It’s hit and miss if they work. Unfortunately, these are HUGE among scammers, so those scammer fucks poisoned the well. Some stores will flat out deny them. Other times, they work fine.
I’ve had probs at some point of sale terminals, others work OK. Ditto gas pumps. Seems to be no way to know which way it’ll go without trying. Which means you gotta have another way to pay lined up.
I haven’t tried them for online shopping yet.
There are cards called green dot money pak, you can only pay cash for them. Well, the kind I bought. You scratch off the back and tell somebody the number. The one I used only had a one time use. Usually I seen people giving money to people that are in jail. Or people try to scam, usually scamming old people. It is actually a good private way to send people money.
