Abstract
A transaction system comprising a card having a card balance recorded therein, at least one terminal transaction processor operable on the basis of on-line and off-line computer schemes, and a center operatively associated with the terminal transaction processor and having a file for recording thereon data corresponding to the card balance recorded on the card. Not only when the terminal processor is operating on the basis of the on-line computer scheme, but also when the terminal processor is operating on the basis of the off-line computer scheme, withdrawal or deposit of money can be effected within the framework of a maximum purchase amount. Each time such transaction has been made, the card balance is updated to read a new card balance.
