Final – A credit card built for the 21st century
> Final lets you give a unique credit card number to every merchant, or a disposable one-time use number for one-off purchases.<p>This is something I have been asking for since forever! People on here claimed it was "impossible" because of how credit cards work, I guess not...<p>> Tired of your monthly yoga pants subscription? Or a two-week "free" trial that lasted four months? Just deactivate that card number. It's that easy.<p>They need to be careful what they advise. That advice could (and likely WILL) result in people getting taken to collections.<p>Don't like your ISP? Just cancel the CC number, then 12 months later get a bailiff turn up and seize your stuff...
