In terms of business logic, is there any other way to ensure that a card is bound to only one user apart from using the card fingerprinting method?
fiery sluice
Then yes fingerprint is the right way.
fiery sluice
Nope, why do you need another way?

However, the same card has different fingerprints on different stripe accounts.
fiery sluice
Do you have multiple Stripe accounts? Are you using Stripe connect?

Suppose we have multiple projects, but we need to ensure that the cards are unique on different projects
fiery sluice
The fingerprint is unique for a given account. This means that if I add the same card to two different Stripe accounts, they will have a different fingerprint.
peak crater
I know this
fiery sluice
So yes it's not possible, unless you use Stripe Connect.

In addition to fingerprints, are there any other fields that can be identified?
