Abstract
A value transfer system for transferring value in transactions between electronic purses as electronic cash has a transaction failure recovery procedure whereby a pending log stores transaction messages after they are sent. On detection of an error an interface device (IFD) can issue a payment resume command to re-send the last transaction message and resume the transaction.
