Zusammenfassung:	The invention provides a method and system for supporting flash card recovery of multiple transactions, and the method comprises the steps: a transaction terminal reads a second card end identifier of an intelligent card, the transaction terminal judges whether a first card end identifier corresponding to the second card end identifier exists in a transaction abnormity list, if yes, the transaction terminal sends a transaction recovery instruction to the intelligent card, and if not, the transaction terminal returns to the intelligent card. The transaction recovery instruction comprises a first terminal random number and a first terminal identifier. And the smart card judges whether a specific log record including a second terminal random number matched with the first terminal random number and a second terminal identifier matched with the first terminal identifier exists in the recovery log file, and if yes, the smart card obtains transaction recovery data from the specific log record and sends the transacti
