I've heard somewhere that Vultr retains your stored credit card indefinitely (even after you close your account). It sounds a bit weird, that's why I avoided their services. Can someone confirm this?
The idea is, if the customer wants to come back and reactivate service they don't have to provide billing details again.
I don't do this though. When customers cancel my startup, I delete the card and cancel the subscription in Stripe but leave the customer.
This is why I am baffled as to why the CC companies eliminated the transient number technology, which was pefect for e-commerce vendors like this. At least with those, after 3-6-12 months the number expires and no damage done when the vendor is hacked. I assume it was dropped because this technology complicated data mining.
