As proposed in another mail by Jacob another option is to enforce restrictions in the

The credit card industry has already standardized a system of merchant categories. Perhaps a small addition to the Taler protocol would be needed for merchants to state their category code (or "unspecified" and the user assigns a category to the transaction) or each user could define their own budgetary categories.
