The following general rules apply for user tokens:
- The user token pertains to a specific customer and is exclusively intended for processing payments belonging to that same customer
- The customer for which a user token is requested/used MUST hold an account with the merchant
- The merchant MUST be able to recognize the user on a return visit
- An iDEAL user token can only be linked to one iDEAL profile, and therefore only one user token can be registered per merchant account per user
