So, I'm debating switching to a debit card for daily purchases, since the mental accounting gets confusing with a credit card and it's easier to overspend. The only thing holding me back is the fraud protection that comes with a credit card. Are there any (US) checking accounts/debit cards that match the level of protection you can expect from a credit card? Is such a thing possible?

Ugh. Scammers are everywhere, and I know I'm getting them in my inbox and junkmail, but I need a way to know who I am wasting my time on and who is a real client.

My current client doesn't seem to speak in the usual way (for example saying "you have replied to me perfectly" in response to me asking "Please let me know if this works for you or if you wish to negotiate"). They want to pay me via a cashier's check. I just now told them I only accept PayPal payments (that is what I've always used). Waiting for a response now.

So my question is, which of these would be the most secure method of payment to use over the internet, with strangers, where contact is via email?

PayPal
Wire transfer
Cashier's check
Other (write in comments)

To start: I was taught in the 90s when I first entered the "internet" that "everything online is public. The End."
I still adhere to that. I am perhaps a bit overly cautious and whatnot, as I will forego convenience to have the feeling of privacy (though in some cases I believe it's just a smokescreen).

That being said, the main premise to my question is this: I have three cards with which I pay for things. I have a debit card which I use for most purchases, a credit card I use for large purchases I can't immediately cover with my bank account, and a credit card for two specific payments. Every December my company gifts all employees a $100 Visa gift card. I tend to splurge on things I'd rather not have show up in my bank account or credit card, because I feel my purchase habits are tracked (similar as to when I put in a local brewery into Waze... and yeah, I use Waze.)

And now to my actual question: is there a credit company, or a method of credit/debit card I can utilize that will not track/share/etc my personal or purchase info? I had never thought of this idea, aside from the gift cards which usually come with some form of caveat (you lose money on fees for a prepaid card, or you can lose your balance if not spent in a certain time frame, etc) until just now I guess. I found privacy.com which looks kind of legit, but ... I'm always skeptical to start.

All that being said, if you could offer any advice or thoughts on the matter, I would greatly appreciate it. Thanks!

(Edit: the original reason I ask this is because I was thinking that I use Discord a lot and would like to throw a few bucks their way and customize my profile or something "fun" like that, but I do not want them to have my info.)

Specifically this week I have to choose whether to create an account with paypal, cashapp or venmo but I am also interested in a broader discussion including other apps. Any advice or information would be welcome.

I used to rely on PayPal heavily for eBay purchases and the odd purchase outside of eBay. But it seems now eBay allows you to use a credit card directly on the site, and most other online stores if they accept PayPal payments, they also accept credit cards directly. Maybe its safe to say I can delete my PayPal account and not look back? It seems like an unnecessary middle man.
