Hi there, I believe you are looking for this https://stripe.com/identity

hey Jack!

Thank you for sharing!

That's not exactly that. As far as i see this is a way to validate customers using documents. But i want to try to validate them using their banking card

Is it possible to use stripe for user verification? e.g. I want to verify if user is unique by checking his card using stripe? Do you have such a service?
Unique in what context? Your Stripe account?

I want to know if I can somehow see if a username is unique. To validate user's name and check if it's real or no. Or visa/master card do not share this info and user can use anything there?
Not sure I understand

Stripe account or unique bank card

i checked visa and mastercard api and looks like it's impossible so there is no question anymore, thank you!

You can use the fingerprint field on a card Payment Method object to check if this card is a duplicate of an existing card: https://stripe.com/docs/api/payment_methods/object#payment_method_object-card-fingerprint

We don't automatically prevent card duplication, a customer can add the same card multiple times. It's up to your integration to prevent that if that's a concern
