|Title:||AN INTEGRATED CIRCUIT DEVICE SUITABLE FOR USE IN A FINANCIAL TRANSACTION PROCESSING SYSTEM|
An electronic circuit device preferably having a form factor of a SIM (subscriber's identification module) card and which is embedded with application software programs for use in a financial transaction processing system designed to utilize near-field communication (NFC) is disclosed. The application software programs contain processing procedures executable for performing an NFC-based outgoing transaction using any of an electronic passbook account, an electronic wallet account, and an electronic checkbook account of an account holder. The SIM card also includes an NFC reader arranged to read an NFC-based incoming transaction request. The integrated circuit device is configured to communicate, via a single wire protocol connection, with an NFC controller of an NFC-enabled electronic device in which the integrated circuit device can be made operable.
