Privacy is a game changer for online transaction security imo. An additional benefit is the ability to subscribe to "try free for a month but oh wait we need your credit card info first so when you forget to cancel we'll keep charging you". Simply create a virtual card with single time spend limit $1 less than the monthly subscription charge, and you can rest assured that your one month trial is a one month trial.
Because then you can get one from transferwise.
In order to use Payment Services, you must be at least 18 years old. You confirm that you are either a legal resident of the United States, a United States citizen or a business entity authorized to conduct business by the state(s) in which you operate and that you are an authorized signatory for the business you represent.
I also use it with sites I don't necessarily trust, like a random auto parts store. If it were a tad easier to use, I'd use it for nearly everything.
With the premium cards on top of other perks there’s also Disposable Cards which creates a virtual card for every transaction you want and as soon as that card gets used, it’ll destroy it and create one brand new.
For separating limits you can create multiple virtual cards each with limits once met will freeze the card.
