As others have mentioned use a credit card instead of debit.

But if you need/want to use a debit card, then take a look at services like Revolut or Wise (non-referal links included).

Both provide you with debit cards that you can enable/disable instantly within their app. Revolut gives you "virtual cards" which can be used for online subscription, so you can create a dedicated virtual card for each subscription (minimizing the impact if/when one of your cards is leaked). Revolut also has "one time use cards", so a new debit card number for a single purchase. In practice, more and more vendors are disallowing "one time use cards", but you can create a similar effect with the virtual cards.

Both platforms also allow you to set up dedicated (monthly) spending limits on either the physical or virtual cards. So you can limit your exposure that way too.

Something tells me you’re keylogged if you keep cancelling, ordering new ones and getting pwned within days of the new card arriving. Format your computers. Use more open source tools whose code you can audit. Firefox instead of Chrome, no sketchy extensions like Honey and cash back stuff. If you pirate stuff, try to do it from verified sources.

A shop you both go to has a machine with a fake overlay swiping your info. You can find online how to spot those. I doubt it's happening online.

For one thing, stop using debit cards on the internet. Credit cards do not take the money out of your account first, thus offering you an additional layer of protection, and many like Discover in the USA are known for offering $0 liability for unauthorized purchases. They can be more of a hassle to use like they may call your mobile number to check on a suspicious purchase, but at this point it seems you want that level of paranoia. Don't miss a rent (or any important) payment bc you have nothing left in your debit account to work with! (Even if it is added back quickly, will it be handled quickly enough?)

You said you use your credit card on Facebook and you're not sure why it's getting stolen .....🙄🤔

Most likely a device that you own is infected. Have you completely delete and reset all your devices?

Have you used these cards in public? Your information could have been picked up by card skimmer.

At least where I live, it's very common to hand payment cards over to wait staff at restaurants. I had my card information compromised during a visit to Boston several years ago.

A lot of other good comments here but I would also recommend not swiping your card at ANY machine. I had my debit card # lifted several times before I finally decided to only use something secure like ApplePay (at the gas pump particularly). Apple Pay changes the card number every single time it’s used. So, it can at least pinpoint the exact moment it was stolen if it somehow did give up your info. I’ve never had to worry about my card number getting stolen since I made that change.

I use Privacy for everything. I can easily cancel and dispute cards and not have to go through the new card song and dance.
