text: Statements on the debit card that say "for medical uses only" are invalid for several reasons: (1) The merchant and issuing banks have no way of quickly determining whether the entire purchase qualifies for the customer's type of tax benefit; (2) the customer also has no quick way of knowing; often has mixed purchases by necessity or convenience; and can easily make mistakes; (3) extra contractual clauses between the customer and issuing bank would cross-over into the payment processing standards, creating additional confusion (for example if a customer was penalized for accidentally purchasing a non-qualifying item, it would undercut the potential savings advantages of the account).
