@tired halo hi! in general fingerprints are the way to go(check the fingerprint of the card the customer is trying to use and then if it matches one on a different customer, you can reject it).
There's no direct API for listing/searching [0] so it comes down to storing locally as you say, or calling https://stripe.com/docs/api/payment_methods/customer_list , for each customer object.
[0] - we do have a Search API in beta(https://stripe.com/docs/search-api) that I think could support this though, so you might try to get access to that.
