In the U.S.A, a FSA debit card only allows medical expenses. It is used by some banks for withdrawals from their FSAs, MSAs, and HSAs as well. They have Visa or MasterCard logos, but cannot be used as "debit cards", only as "credit cards"", and they are not accepted by all merchants that accept debit and credit cards, but only by those that accept FSA debit cards. Merchant codes and product codes are used at the point of sale (required by law by certain merchants by certain dates in the USA) to restrict sales if they do not qualify. Because of the extra checking and documenting that goes on, later, the statement can be used to substantiate these purchases for tax deductions. In the occasional instance that a qualifying purchase is rejected, another form of payment must be used (a check or payment from another account and a claim for reimbursement later). In the more likely case that non-qualifying items are accepted, the consumer is technically still responsible, and the discrepancy could be revealed during an audit.
