I had a similar thing recently. As I understand it, AWS uses a digital token for your added a credit card. Contact your card provider to renew/rotate/delete the digital token that is attached to your card. That should stop charges. Doing that obviously might impact other services for which you use that card so you might need to re-add your card to those services.

Generally tokenization is done by some vault or processor. I don't know how Amazon operates internally, due to their scale means it's probably all in house. But Visa does have token representations and they do also have visa account updater (which keeps visa/merchants in sync for saved instruments .. e.g. Netflix). I've never seen the token implemented, generally just some vault (Braintree, Spreedly, etc). And if you are typing in a 15/16 digit number it's likely being vaulted/tokenized but not by the issuer but by the merchant/processor.
