> Final lets you give a unique credit card number to every merchant, or a disposable one-time use number for one-off purchases. 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... > 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…
I previously worked at a web hosting company where people would pull this kind of thing. Generally we didn't bother with collections because it was often more hassle than it was worth (the biggest part of our cost was the support and anti-fraud process, not the actual service), but nonpayment would get accounts deactivated and blacklisted automatically, so they'd have to call in to us (and get recorded in our tracking system in case of repeat incidents) to pay and get things turned back on.
I had some sympathy for people dealing with accidental credit card expirations, but there was always a weird minority of people who would knowingly and sometimes repeatedly cancel cards or dispute payments and yet get angry at us for the audacity of turning off their websites.
