Abstract
A portable terminal device is adapted to effect transaction operation by transmitting and receiving data to and from a central unit. When transaction data is entered, the transactions including the current transaction are accumulated, and when the accumulated transaction exceeds a predetermined limit determined by a preset transaction limiting data, the transaction based on the input data is inhibited.
