If you plan to give or sell a previously registered Eye-Fi Card you will have to delete the card from its associated account before it can be registered and used by another person. For instructions about deleting an Eye-Fi card from an Eye-Fi account refer to How do I add/delete an Eye-Fi Card to/from my account?.

If you plan to purchase a used Eye-Fi Card, it is imperative that you make sure that the previous user has deleted the Eye-Fi account associated with the Eye-Fi Card you plan to purchase. A previously registered Eye-Fi Card cannot be re-registered to a new user until the previous account has been deleted by the original owner/user of the card.

Important: Eye-Fi Customer Care cannot delete customer confidential information associated with an Eye-Fi Card or customer account
