PORTABLE ELECTRONIC DEVICE HAVING A MEMORY CARD MODULE FOR CONDUCTING ELECTRONIC TRANSACTIONS

摘要

A portable electronic device is provided for conducting an electronic transaction with a point-of-sale (POS) terminal, and includes a device processor, and a memory card module. The memory card module includes a transceiver unit to receive transaction data from the POS terminal, a storage unit including a working zone and a hidden zone that stores the transaction data, and a processing unit. The transaction data stored in the hidden zone is accessible only to the processing unit. The processing unit is responsive to control by the device processor that executes a read-only control application stored in the working zone for accessing the transaction data stored in the hidden zone.
