Abstract
A system and method for authorizing transactions where a terminal determines if the transaction amount is within a low value limit. If so, a card acts within the parameters of offline counters on the card to generate an offline authorization. The transaction amount is deducted from the available funds balance tracked by an additional counter on the card. Merchants clear the transaction during batch processing in the same manner as other debit or credit transactions. The transactions are treated as standard chip offline-authorized transactions and are sent with other transaction details to an issuer.
